Salt stress is one of major restrictions for the production of lettuce. In order to identify promising lettuce genotypes having tolerance against salt stress, effect of different sodium chloride (NaCl) concentrations (0, 100, and 200 mM) on electrolyte leakage and growth of thirty-two lettuce landraces from Korea was evaluated. Screening salt tolerant genotypes based on cluster analysis using data of electrolyte leakage discriminated 'IT105183' and 'IT195057' as the most salt tolerant landraces. More importantly, salinity significantly reduced growth of lettuce, but the reduction rates of growth caused by salt stress in salt-tolerant genotypes were much smaller than those in salt-sensitive genotypes. These results indicate that 'IT105183' and 'IT195057' have high potential for being used as parents to improve salt tolerance in other lettuce cultivars.

The rice recombinant inbred lines derived from Milyang23 and Gihobyeo cross were used in genetic mapping and QTL analysis studies. In this study, we developed a new 101 CAPS markers based on the SNPs in the whole genome region between these varieties. As a result, the total genetic distance and average distances were 1,696.97 cM and 3.64 cM, respectively. In comparison to the distance of the previous genetic map constructed based on 365 DNA markers, the new genetic map was found to have a decreased distance. The map was applied for the detection of QTLs on all seven traits relevant to diameter of stem internode, length of culms, length of panicles and the number of panicles including the correlation analysis between each trait. The QTLs results were similar to the report in previous studies, whereas the distance between the markers was narrowed and accuracy increased with the addition of 101 CAPS markers. A total of 9 new QTLs were detected for stem internode traits. Among them, qI1D-6 had higher LOD of 5.1 and phenotype variation of 50.92%. In this experiment, a molecular map was constructed with CAPS markers using next generation sequencing showing high accuracy for markers and QTLs. In the future, developing more accurate QTL information on stem internode diameters with various agriculturally important traits will be possible for further rice breeding.

The amylose contents of rice determine eating quality which is one of the major traits in rice breeding program. To identify the low-amylose gene of the japonica rice cultivar Baegjinju, genetic analysis was conducted using 200 F₂ population derived from a cross between the japonica cultivars, Saeilmi and Baegjinju. Individual F₂ plants were classified as wild type (translucent grain) and mutant type (dull grain) based on the grain appearance of brown rice. Two hundred F₂ plants were segregated into 155 wild type plants and 45 mutant type plants, which fit the 3:1 ratio (x² = 0.667, df = 1, p = 0.414) and this result indicated the low-amylose gene of Baegjinju is a single recessive gene which controls the amylose contents. Linkage analysis was conducted to localize the low-amylose gene of Baegjinju and fine mapped within an 800-kb interval between 17.5 to 18.8Mb on short arm of chromosome 10. Co-segregated SSR marker, RM25648 was developed and it could be useful for marker-assisted selection and determination of the genetic resource related with amylose contents in rice breeding.

The 12 cultivars of the Jeju native Citrus are considered to have originated from China. However, the origin of the cultivar ‘Byungkyool’ (Citrus platymamma Hort. ex Tanaka) is not clearly known. We performed PCR analysis by using three primer sets designed from the internal transcribed spacer (ITS) region of nuclear ribosomal DNA (nrDNA) to analyze the phylogenetic relationship between the traditional citrus cultivars and the Byungkyool cultivar. Sequence length of the nrDNA ITS1 region of JNCPCRI (Jeju Native Citrus platymamma Citrus Research Institute) cultivar was 247 bp, 8the ITS2 region was 228 bp and the total ITS region (ITS1-5.8S-ITS2) was 638 bp. Analysis of the genetic relationship based on the sequence analysis at the ITS region of the JNCPCRI cultivar revealed that the ITS1 region of the cultivar was genetically the same as that of the Byungkyool (JQ990189) cultivar, and the ITS2 region was genetically similar to the Binkyool (JQ990180), Hongkyool (JQ990178), Dangyooja (JQ990179), and Pyunkyool (JQ990181) cultivars. Moreover, the total ITS region in the 5.8S rDNA region was genetically similar to the Hongkyool (JQ990178) cultivar. In addition, the total ITS region of the JNCPCRI cultivar was the most closely related to the Cheongkyool (JQ990183) cultivar and has been reported to originate from the Binkyool (JQ990180) and Pyunkyool (JQ990181) cultivars. Although the JNCPCRI cultivar was morphologically the same as the Byungkyool (JQ990189) cultivar, the ITS region showed genetic heterogeneity. Taken together, we conclude that the genetic variation in the ITS region of JNCPCRI cultivar suggests that it was propagated through fertilization with the surrounding citrus cultivars.

The International Union for the Protection of New Varieties of Plants (UPOV) promotes an effective system of plant variety protection and encourages the development of new varieties of plants. This international convention was initiated to standardize the system efforts and strengthen policy. The establishment of cultivar discrimination system is very important to distinguish varieties between domestic and foreign agricultural products. It is necessary for the protection of breeders’rights. In addition, it will help for more efficient and quality management of plant breeding. This study was conducted to identify and group rice varieties based on agro-morphological characteristics such as plant height, panicle length, number of tillers, culm length, leaf length, leaf width, leaf pigments and flag leaf angles. Using these parameters, statistical analysis classified a total of 243 rice varieties bred in Korea into four groups. Most rice varieties did not exhibit anthocyanin pigments on the leaves particularly on the first leaf, leaf blade, leaf sheath and auricle, except for varieties classified as black rice. Results of phylogenetic and principal component analysis (PCA) indicated that these varieties formed three largely distinct clusters according to their ecotype and morphological differentiation. This result would be useful in rice varietal identification for the protection of breeders’variety rights.

Cup arrangement ranking method (CARM) is a method for a rapid and small-sample sensory evaluation of cooked rice in rice breeding program. This study was compared to four different scale ranges (1~11, 1~9, 1~7 and 1~5) for improving the efficiency of CARM using sixteen Japonica and four Tongil-type cultivars. The wide scale ranges were higher of that than narrow scale range on determination coefficient between standard sensory evaluation method (SSEM) and CARM. However, the wide scale ranges were required more time and efforts than those of the narrow scale ranges for eating sensory evaluation of cooked rice. The wide scale ranges of 1~11 and 1~9 were difficult to distinguish the differences between the cultivars in the scale 3 and 4. On the other hand, the narrow scale ranges of 1~7 and 1~5 could distinguish the difference between cultivars in all scales. We suggest that two scale ranges for CARM were 1~7 (7 classes) in including Tongil type cultivars and 1~5 (5 classes) in Japonica cultivars.

Grain size has a great impact on rice grain yield and is controlled by quantitative trait loci (QTL). Daeribbyeo 1 with big grain is widely used for genetic materials to develop varieties with diverse grain size. This study was conducted to identify genes controlling grain size traits of Daeribbyeo 1. An F_2:3 population derived from a cross between two japonica cultivars, Boseogheugchal and Daeribbyeo1, was used to identify QTL controlling grain shape traits. A total of 284 F₂ plants were measured for grain shape traits, grain length (GL), grain width (GW), grain thickness (GT), 1,000 grain weight (TGW), and two morphological traits, pericarp color and waxy endosperm. Sixty F₃ lines were selected based on the grain shape traits and marker genotypes and evaluated for grain shape traits. For marker analysis, SSR markers tightly linked to five known grain size genes and two QTLs were selected and used for genotyping. A total of 11 QTLs detected on chromosomes 2, 3, 4 and 6 explained phenotypic variation from 3.9% to 59.3%. qTGW2, qGW2 and qGT2 were detected in the same region between RM12811-RM12837 that are tightly linked with GW2 gene. qTGW3 and qGL3 were detected near GS3 gene. To know whether Daeribbyeo 1 has the same mutations in GW2 and GS3 as the various grain-size genotypes, GW2 and GS3 of two parents were sequenced. Daeribbyeo 1 had the same one base (A) deletion at a position 316 as ‘WY3’ in GW2 which results in the loss of function of GW2 gene. Boseogheugchal showed a C-to-A nonsense mutation in the second exon of GS3 gene that increased grain length. Interaction between GW2 and GS3 was not significant indicating that two genes controlled grain-size traits in additive pathway. The results from this study indicate that three QTLs GW2, qGT4 and qGL6 are associated with the grain size variation in Daeribbyeo 1 with GW2 as the major QTL.

A new peanut variety ‘Huaseon’ (Arachis hypogaea ssp. hypogaea L.) was developed at the Department of Southern Area Crop Science, National Institute of Crop Science (NICS) in Milyang 2013.

‘Daanok’, a new maize F₁ hybrid (Zea mays L.), is developed by the maize breeding team at the National Institute of Crop Science (NICS), RDA in 2013. The high-yielding hybrid, named ‘Daanok’ was bred by crossing between two inbred lines, ‘KS174’ and ‘KS175’. It is a yellow semi-flint maize hybrid (Zea mays L.). After preliminary yield trial and advanced yield trial of Daanok in Suwon for two years, regional yield trial of that was subsequently carried out for evaluation of its growth and yield at three different locations from 2011 to 2013. The silking date of Daanok is earlier than that of the check hybrid, ‘Jangdaok’. The plant height of Daanok is 229cm, similar to Jangdaok, and its ear height ratio is similar with that of Jangdaok.It has resistance to lodging. There are much of the No. of ear per 100 plants. The ear length of Daanok is similar with that of Jangdaok. The weight of 100 seeds of Daanok is the same with that of Jangdaok. It has strong resistance to northern leaf blight (Exserohilum turcicum) and southern leaf blight (Bipolaris maydis). It has strong resistance to ear lot. It has moderate resistance to corn borer. The grain yield (7.34 ton/ha) of Daanok was 23% higher than that of Jangdaok. The seed production of Daanok has gone well due to a good synchronization of flowering period during crossing between the seed parent, KS174, and the pollen parent, KS175, in Yeongwol and F1 seed yield was 2.38 ton/ha. Daanok would be a suitable cultivar to all plain area in Korea.

The 'Misomi' is a rice variety derived from a cross between ‘Sobi’ which has adaptability of low fertilizer cultivation and SR21110 (Ilpum/Jinbu19) by the rice breeding team at National Institute of Crop Science, RDA in 2013. The heading date of ‘Misomi’ is August 14 and six days later than check variety, ‘Hwaseong’. It has 83 cm of culm length and 121 spikelets per panicle. It showed weaker cold tolerance than that of ‘Hwaseong’ during exposed to cold stress. ‘Misomi’ showed resistance to blast disease, K1, K2 and K3 race of bacterial blight and stripe virus, but susceptibility to K3a race, other viruses and planthoppers. The milled rice of this variety exhibits translucent, clear non-glutinous endosperm and short grain shape. It has low protein content (6.2%) and similar amylose content (19.4%) to that of ‘Hwaseong’. ‘Misomi’ showed better palatability index of cooked rice than that of ‘Hwaseong’. Particulary, ‘Misomi’ showed excellent processing adaptability than ‘Chucheong’ and ‘Hwaseong’ on palatability index of cold and aseptic cooked rice. Its milled rice recovery rate is similar to those of ‘Hwaseong’. However, whole grain rate of milled rice is higher than that of ‘Hwaseong’. 'Misomi' has 5.68 MT/ha of milled rice productivity in ordinary cultivation, which was 12% higher than that of ‘Hwaseong’. 'Misomi' could be adaptable to the middle plain area and Midwest coast area in Korea (Grant No. 5635).

The wheat-rye translocations are world widely used in wheat breeding. Among the various forms of wheat-rye translocation, the 1RS (short arm of rye chromosome 1) translocations are the most widely used because of the valuable genes (e.g. biotic / abiotic resistance genes) introduced from rye. We have developed a new wheat-rye cultivar ‘TRANS’ which have freezing resistance and high yield in this study. ‘TRANS’ is a new wheat-rye translocation cultivar developed by crossing between common wheat ‘Keumkangmil’ and ‘951188-G3-G1’, a 1AL.1RS translocation derived from ‘Fleming’ with the aim of high yield and resistant genes to various unfavorable environments carried by 1RS. ‘TRNAS’ have clearly different genetic and agronomic traits to the control cultivar ‘Keumkangmil’. The heading date and maturity of ‘TRANS’ are later than that of ‘Keumkangmil’. ‘TRANS’ has 1023 spike number per square meters and grain yield of 541 kg/10a, which are higher than ‘Keumkangmil’ (904 spike number/m² and 504 kg/10a yield). ‘TRANS’ showed winter hardiness and powdery mildew resistance in artificial infection test and field evaluation. ‘TRANS’ gives lower flour yield than ‘Keumkangmil’ but ash and protein content were similar to that of ‘Keumkangmil’. The color of flour and noodle dough of ‘TRANS’ were darker than ‘Keumkangmil’. Quality parameters related to milling, flour quality, noodle dough and end-use quality of ‘TRANS’ indicates that ‘TRANS’ is soft wheat suitable for noodle making. ‘TRANS’ can be cultivated in entire part of Korea.

A new rapeseed (Brassica napus L.) variety ‘Jungmo 7003’ is with early flowering and disease tolerance, which has white petals. ‘Jungmo 7003’ was developed from the cross between ‘Tower’ as female parent and ‘AB130’ as male parent in 1983. The selection for advanced lines with white flower had been done by the pedigree method. A promising line, ‘83025-B-1-1-2’, was selected and designated as the name of ‘Mokpo113’. It had good results from regional adaptation yield trials at four locations for two years from 2013 to 2014 and was released as the name of ‘Jungmo 7003’. ‘Jungmo 7003’ has light-green and middle parted leaf, light-green stem and black seed coat. Since, the prominent very special trait of ‘Jungmo 7003’is white flower, it can be used for landscaping purposes created farm-art images. The flowering date of ‘Jungmo 7003’ was 16^th April and ripening date was 5^th June. The yield of ‘Jungmo 7003’ was 207 kg/10a, which was 6% lower than ‘Hanlayuchae' in regional adaptation trials. ‘Jungmo 7003’ showed high resistance to screrotium. The oil content of ‘Jungmo 7003’ was 43.8%. In fatty acid composition of ‘Jungmo 7003’, oleic acid content is 68.4%, which is 1.2% higher than ‘Hanlayuchae'. ‘Jungmo 7003’ will be adaptable to southwestern area including Jeonllanam-do, Jeollabuk-do and Gyeongsangnam-do and Jeju island of Korea.

‘Hyesun’, a new cultivar of leaf lettuce (Lactuca sativa L.) with sharply wrinkled oval and red leaf, produced by a cross between 'Nongjeockchima’ (red leaf color) and ‘Jeockchima’ (high yield) has late bolting and high yield in the field. The cross and selection for advanced lines had been done by the pedigree method from 2002 to 2008. The ‘Hyesun’ has gray seed color and medium elliptic leaves. The yield and adaptability of the advanced lines were evaluated at several locations of Korea (Gangwon-do, Gyeonggi-do, Chungcheongbuk-do, Jeollabuk-do, Gyeongnam-do, and Jeju-do) for 3 years (from 2009 to 2012). The type of maturity of ‘Hyesun’ is early-medium. The leaf hardness of ‘Hyesun’ is a 1,237kg/cm², which is not thicker than ‘Yeolpungeokchima’. The anthocyanin content of 'Hyesun' is a 88.32mg/100g, which is lower than that of ‘Yeolpungeockchima’. The BSL (Bitter Sesquiterpene Lactones, latucin + 8-deoxylactucin + lactucopicrin) content of ‘Hyesun’ is a 5.0ug/g of DW, which is lower than that of ‘Yeolpungeockchima’. Compared to ‘Yeolpungeockchima’, marketable yield of ‘Hyesun’ was higher by 7% (at 381g per plant) and the bolting time of ‘Hyesun’ was remarkably delayed under high temperature cultivation in the field. The shelf-life of ‘Hyesun’ was four weeks longer than ‘Yeolpungeockchima’ at 4°C. Furthermore, because ‘Hyesun’ is more crispy and sweeter than ‘Yeolpungeockchima’, ‘Hyesun’ has the better taste. So, we recommend that the new cultivar ‘Hyesun’ can be suitable for cultivation in both spring and fall season.

Kenaf (Hibiscus cannabinus L.) is an annual herbaceous crop of the Malvaceae family. Recently, kenaf is being used in many diversified applications such as pulp, animal feed, bioplastics and cellulosic biofuel etc. A new cultivar 'Jangdae' was developed by mutation breeding using irradiated with 300 Gy gamma-rays. Jangdae has a few distinguishable characteristics such as early flowering, high seed yield and palmate leaf, compared to wild type (Jinju). The fresh matter (FM) and dry matter (DM) yield of Jangdae are similar to those of Jinju, their seed yield (833.3 kg/ha) is approximately 4 times higher than that of Jinju. In addition, the FM and DM yield of Jangdae are 40% higher than those of early-maturing cultivar (C11). We performed the nutritive value of four kenaf cultivars (Jangdae, Jinju, C11 and Hongma300) at 100 day after seeding. The crude protein content of Jangdae, Jinju, C11 and Honma300 were 10.5, 11.0, 9.4 and 10.6%, respectively. The crude fiber, neutral detergent fiber and acid detergent fiber contents were no significant difference among the cultivars. Jangdae, which afforded both a high biomass and seed yield in South Korea, may be useful as potential source of feed and industrial materials.

‘Geonhwangmi’, a new sweetpotato variety, was developed for table use by Bioenergy Crop Research Institute, National Institute of Crop Science (NICS), and RDA in 2013.

The regional yield trials were conducted at five locations from 2011 to 2013, and it was named as ‘Geonhwangmi’. This variety has five-lobed leaf, and its leaves, stems, and petioles are green. Storage root of ‘Geonhwangmi’ has an elliptical shape, red skin, and light orange flesh. ‘Geonhwangmi’ was moderately resistant to fusarium wilt, and resistant to root-knot nematode. Dry matter content was 29.4%, and texture of steamed storage root was intermediate. Sucrose content of steamed storage root of ‘Geonhwangmi’ was higher than that of ‘Yulmi’, and steamed storage root palatability of ‘Geonhwangmi’ was better than that of ‘Yulmi’. β-carotene content of ‘Geonhwangmi’ was 3.4 mg/100g DW, which was 7.8% of ‘Juhwangmi’. Yield of marketable storage root over 50 g of ‘Geonhwangmi’ was 23.0 MT/ha under the early seasonal cultivation, which was 39% higher than that of ‘Yulmi’. The number of marketable storage roots per plant was 2.6 and the average weight of marketable storage root was 151 g under the optimal and late seasonal cultivation. Marketable storage root yield of ‘Geonhwangmi’ was 24.2 MT/ha under the optimum and late seasonal cultivation, which was 45% higher than that of ‘Yulmi’. (Registration No. 5853).

'Cheongpungheukhyangchal' New aromatic, black pericarp and glutinous rice variety was developed by the rice breeding team of Chungbuk Agricultural Research and Extension Services, in 2012. This cultivar was derived from a cross between 'Shindongjin' as a grain quality source and 'Heugseonchal' as a black glutinous and aromatic source. The donor parent, 'Sindongjin' has been backcrossed one time with recurrent parent 'Heugseonchal' and selected by the pedigree breeding method, until F₆ generation. As a result, a promising line, CBR11-2-4-3, was advanced and designated as the name of ‘CBR L3’ in 2009. The maturity period of this cultivar took approximately 168 days from seedling to heading. This cultivar has about 15 tillers per hill and 115 spikelet numbers per panicle. Ripening ratio is about 76.5% and 1000 grain weight is 27.2 g in brown rice. Milled rice of 'Cheongpungheukhyangchal' has trait of glutinous and aromatic endosperm. It has higher anthocyanin content compared to that of black pigmented check cultivar ‘Heugseonchal’. The yield performance of brown rice was 5.39 MT/ha in local adaptability test for three years. ‘Cheongpungheukhyangchal’ is adaptable to central plain and southern mid-mountainous area of Korea.

As the farmers who grow Chinese matrimony vine (Lycium chinense Miller) in rain-shelter greenhouses increase, it is necessary to develop a cultivar with early-flowering. In addition, the new varieties should be continuously selected in order to adapt to climate change and to respond to future demands. The new line, CB07423-104, was selected from the cross between Cheongmyeong (IT232706) and CB04341-286 in 2007 to breed a cultivar with early flowering and high yielding. Its preliminary yield tests were performed from 2009 to 2010 and the selected line was named Cheongyang 17. Its regional yield trial was carried out in Cheongyang, Yesan and Jindo from 2011 to 2013 and Cheongyang 17 was registered as the new variety, ‘Cheonghong’ (Certificate on grant of plant variety rights: Grant number No.5642, Protection period 06/07/2015 ~ 05/07/2035) in 2013. The major characteristics were summarized as follows;

The plant shape was spreading type. Leaf had ellipsoidal small sizes and 3~5 leaves on a node. The fruit was oblong and yellowish red. The flowering time was June 17 and faster about 11 days than the check ‘Cheongmyeong’. The branching was generated less than the check variety. This cultivar has a lot of flowers bloom per a node and many fruits per a plant. The resistances to anthracnose and eriophyidae mite were a little better than that of the check variety. The content of betaine of dried-fruit and brix degree of fresh fruit were higher than those of the check. The dried-fruit yield was 16 percent higher than the check at regional yield trials conducted at Cheongyang, Yesan and Jindo. Applications are customarily available in both medicinal and edible. This variety has self-incompatibility. So, the companion variety, Cheongmyeong, was required as pollinizer and recommended to plant 1 : 1.

A new small red bean cultivar, ‘Arari’, was artificially crossed between ‘SA9411-2B-1-1-2’ and ‘Suweon38’ in 1997, fixed excellent agronomic characters by pedigree breeding method, and selected for the further trials with the name of 'Milyang 8'. It was prominent and showed good result, such as high grain quality, Lodging resistance, and high yielding, from the regional adaptation yield trials (RYT) for three years from 2009 to 2011 and released for the public consumption as the name of ‘Arari’in 2011. ‘Arari’ has a semi-determinate growth habit, yellow flower, green embryonic axis, dark red seed coat, white hilum, and small spherical seed (13.1 grams per 100 seeds). The average yield of ‘Arari’ was 2.05 MT/ha in the regional yield trials (RYT) carried out for three years from 2009 to 2011 which was a little higher than that (1.99 MT/ha) of check variety, ‘Chungju’.

Jungmo1019 early maturing rice variety was developed by the rice breeding team of the Department of Southern Crop, NICS, RDA in 2011. This cultivar was derived from the cross Hwayeongbyeo//Hitomebore/Nampyeongbyeo made in 2005 and the production of doubled haploid rice plant from anther culture in F₁ generation. Testing in the replicated yield trial in 2008, a promising line YR25312Acp62 was selected and it was designated as the Milyang246. The early traus plauting local adaptability test of Milyang246 was carried out at three location in 2011 and it was named as Jungmo1019 showing a high head rice ratio and early–maturity eco-type. Number of spikelet/panicle and 1,000 grain weight of brown rice was slightly lower than those of Jopyeongbyeo. This variety is resistant to bacterial blight, rice stripe virus disease but susceptible to major insect and pests. The milled rice yield of Jungmo1019 is 4.52MT per ha at the early transplanting of the local adaptability test. This line should serve as a useful source for improving head rice ratio at early transplanting cultivation in southern plain area.

'Hyowon 2’, a new medium-late maturing glutinous rice variety with short clum and lodging tolerance was developed by the rice breeding team of Pusan National University in 2013. This cultivar was derived from a cross between 'Junam’ as a short clum source and ‘Donna’ with a good glutinous properties. During selected by the pedigree breeding method, until F8 generation. As a result, a promising line, JS22-3-24-1-6-2-1-1-1, was advanced and designated as the name of ‘SP 105’ in 2012. This variety headed on Aug. 22 is 9 days later than ‘Dongjinchal’ in middle plane. The Culm length and panicle length of this variety was 65.6 cm and 22.5 cm, respectively. This variety has about 14.4 tillers per hill and 113 spikelet numbers per panicle. The ratio of ripened grain is about 93.0% and 1000-grain weight was 18.4 g in brown rice. This variety has higher α-tocotrienol content compared to that of ‘Hwasunchal’. The yield performance of brown rice was 4.81 MT/ha in local adaptability test.

"Hyowon 5’, a new aromatic rice variety with high yield was derived from a cross between 'Dasan’ as a high yield source and ‘IR841-1-1-2’ as a donor for aroma. A general pedigree breeding method was applied to develop Hyowon 5. In F₈ generation, a promising line, JS14-12-36-8-5-3-1-1-1, was selected and designated as the name of ‘SP 102’ in 2012. This variety headed on Aug. 14 , which is 3 days later than ‘Hwayoung’ in middle plane. The brown rice of this aromatic variety ‘Hyowon 5’ exhibited 51 odor-active volatiles including a pop corn-flavoring 2-acetyl-1-pyrroline which is exclusively detected in aroma rice varieties. The Culm length and panicle length of this variety was 83.2 cm and 26.4 cm, respectively. This variety has about 14.9 tillers per hill and 124.5 spikelet numbers per panicle. The 1000-grain weight was 20.9 g in brown rice. The yield performance of brown rice was 6.27 MT/ha in local adaptability test.
