Note that the agronomic traits were evaluated by harvesting 100 plant for each replication plot (n=3), which were planted as three seedlings per plant during transplanting. All numerical values were mean ± standard deviation.

zThe primer sequences were used as the query to localize on Rice Pseudomolecule 6
yWhen both primer sequences successfully recognized their physical locations to be annealed, the expected PCR product size (e-PCR:‘Stop’-‘Start’+1bp, NA=not available) was used to judge PCR products. If any primer failed for e-Landing, the other primer's result was adopted to estimate the corresponding point. The determined physical regions followed by e-Landing were used to match corresponding BAC/PAC clones depend on the ‘Rice Pseudomolcule Information and Gene Search’ (http://rice.plantbiology.msu.edu/)
xThe determined cM positions for each BAC/PAC clones was directly adopted from the ‘Rice Pseudomolcule Information and Gene Search’ which were estimated using the marker sequences obtained from the Cornell Rice Genes Database and the Japanese Rice Genome Program. To take some convenient in comparing the cM positions from various mapping populations having different total lengths, the percentage expressed relative genetic positions, ‘cM%’, was also calculated
wA and B are homozygous for the Namil(SA)-bl5 and Milyang23 allele types, H is for heterozygous progenies at the tested locus, and M indicates the number of missing. Segregation distorted loci are indicated with asterisk; χ2 values for the significant levels are less than 0.05

zOnly significant loci to each trait tested are presented. 58 DNA markers were tested in 94 F2 progenies derived from the cross between Namil(SA)-bl5 and Milyang23.
yBoth cM positions and the percentage expressed relative genetic positions (cM%) are presented.
xF2 progenies were split into three subgroups based on the revealed genotype by SSR markers. A and B are homozygous for the Namil(SA)-bl5 and Milyang23 allele types and H indicates heterozygous progenies at the tested locus.
wThe means of each subpopulation for each locus are calculated.
vFor the F-test, SSR markers having less than significant levels (p) were declared as significant empirically. Explainable phenotypic variation portion at the tested locus (R2) was also calculated. The significant levels are less than 0.05
***significant at P<0.001
**significant at P < 0.01
*significant at P < 0.05.
uAdditive effect (Add), domiant effect (Do) and degree of dominance (DeD) were then estimated at the declared loci: Add=(Bmean-Amean)/2, Do= Hmean-(Bmean+Amean)/2, and DeD=Do/Add. where A and B are homozygous F2 individuals for Namil(SA)-bl5 and Milyang23, H is heterozygous individuals at the tested locus.

The primer sequences were used as the query to localize on Rice Pseudomolecule 6
When both primer sequences successfully recognized their physical locations to be annealed, the expected PCR product size (e-PCR:‘Stop’-‘Start’+1bp, NA=not available) was used to judge PCR products. If any primer failed for e-Landing, the other primer's result was adopted to estimate the corresponding point. The determined physical regions followed by e-Landing were used to match corresponding BAC/PAC clones depend on the ‘Rice Pseudomolcule Information and Gene Search’ (
The determined cM positions for each BAC/PAC clones was directly adopted from the ‘Rice Pseudomolcule Information and Gene Search’ which were estimated using the marker sequences obtained from the Cornell Rice Genes Database and the Japanese Rice Genome Program. To take some convenient in comparing the cM positions from various mapping populations having different total lengths, the percentage expressed relative genetic positions, ‘cM%’, was also calculated
A and B are homozygous for the Namil(SA)-bl5 and Milyang23 allele types, H is for heterozygous progenies at the tested locus, and M indicates the number of missing. Segregation distorted loci are indicated with asterisk; χ2 values for the significant levels are less than 0.05

Only significant loci to each trait tested are presented. 58 DNA markers were tested in 94 F2 progenies derived from the cross between Namil(SA)-bl5 and Milyang23.
Both cM positions and the percentage expressed relative genetic positions (cM%) are presented.
F2 progenies were split into three subgroups based on the revealed genotype by SSR markers. A and B are homozygous for the Namil(SA)-bl5 and Milyang23 allele types and H indicates heterozygous progenies at the tested locus.
The means of each subpopulation for each locus are calculated.
For the F-test, SSR markers having less than significant levels (p) were declared as significant empirically. Explainable phenotypic variation portion at the tested locus (R2) was also calculated. The significant levels are less than 0.05
significant at P<0.001
significant at P < 0.01
significant at P < 0.05.
Additive effect (Add), domiant effect (Do) and degree of dominance (DeD) were then estimated at the declared loci: Add=(Bmean-Amean)/2, Do= Hmean-(Bmean+Amean)/2, and DeD=Do/Add. where A and B are homozygous F2 individuals for Namil(SA)-bl5 and Milyang23, H is heterozygous individuals at the tested locus.
Rice blast isolates were collected from Korean famers’ fields. Resistance degrees of virulent rice blast were classified five levels from 1 (resistance) to 5 (susceptibility). Korean rice cultivars, Junam, Onuri, and Chilbo were included as check varieties

Heading date (HD), Culm length (CL), Panicle length (PL), Tiller number (TN), Spikelet number (SN), Ripened grain percentage (RGP), 1,000-grain weight of hulled grain (TWD), and Yield of brown rice (YDB). Note that the agronomic traits were evaluated by harvesting 100 plant for each replication plot (n=3), which were planted as three seedlings per plant during transplanting. All numerical values were mean ± standard deviation.
