Bakanae disease is caused by several species of Fusarium and imposes serious limitations to rice production worldwide. The incidence of this disease is increasing in the top rice-growing countries. No rice variety has been found to be completely resistant to this disease. Thus, higher resistance to the disease may be a cost saving solution preferable to the application of fungicides. ‘Anpyeong’ was derived from the cross between ‘YR24982-9-1’ and ‘Saeilmi’ in 2012 and selected as the promising line, ‘YR30389-B-2GH-103’; it was further selected and designated as ‘Milyang 313’ in 2016. The local adaptability test for ‘Milyang 313’ was conducted at five locations from 2016 to 2018 and the cultivar was named ‘Anpyeong’. The heading date for the medium-late maturing cultivar ‘Anpyeong’ was August 13. The ‘Anpyeong’ culm was 77 cm long and had 115 spikelets per panicle. The brown rice 1,000 grain-weight was 22.2 g, which is higher than that of ‘Nampyeong’. This variety is resistant to blast disease and rice stripe virus, but susceptible to bacterial blight and insect pest. The potential ‘Anpyeong’ yield was approximately 562 kg/10 a at ordinary fertilizer level in the local adaptability test and for three years. ‘Anpyeong’ harboring the qBK1 gene derived from a tongil type rice ‘Shingwang’ is moderately resistant to bakanae disease (Registration No. 8135).

Bakanae disease is an important fungal disease caused by Gibberella fujikuroi. Incidence of rice bakanae disease creates serious problems in the foremost rice producing countries, affecting more or less all known rice cultivars. Breeding rice cultivars resistant to bakanae disease will thus be a cost-effective alternative to the application of fungicides. ‘MY299BK’ was derived from a cross between YR24982-9-1 and ‘Ilpum’ in 2008. A promising line, YR28297-1-38-1-1, was selected from among the progeny and designated ‘Milyang299’ in 2013. The local adaptability test of ‘Milyang299’ was carried out at five locations from 2014 to 2016 and named ‘MY299BK’. The heading date of ‘MY299BK’ was Aug. 15, typical for a medium-late maturing cultivar. Its culm was 71 cm long, there were 114 spikelets per panicle, and 1,000 grain-weight of brown rice was 23.4 g; these parameters were similar to those of ‘Nampyeong’. ‘MY299BK’ cultivar was resistant to blast and rice stripe virus, but susceptible to bacterial blight and insect pests. Its yield potential was about 566 kg/10 a at ordinary fertilizer level in a three-year-long local adaptability test. ‘MY299BK’ resistance to bakanae is conferred by the qBK1 gene derived from a tong-il type rice ‘Shingwang’ (Registration No. 7651).

Nunkeunheugchal (registration No. 01-0001-2014-4), a black waxy giant embryo rice cultivar, was developed by the rice breeding team of National Institute of Crop Science (NICS), RDA in 2012. This cultivar was derived from the cross between ge^t and Josaengheugchal in 2004/2005 winter season, and selected by a promising line, YR25277-B-B-314-2, was selected and designated as the line of Milyang263 in 2009. The local adaptability test of Milyang263 was carried out at four locations from 2010 to 2012 and it was named as Nunkeunheugchal. This variety is a early maturity cultivar. It has 65 cm in culm length and 72 spikelets per panicle, and 1,000 grain-weight of brown rice is 17.8 g which is less than that of Josaengheugchal. This variety is resistant to leaf blast, but susceptible to bacterial blight, neck blast, virus disease and insect pest. The yield potential of Nunkeunheugchal was about 3.54 MT/ha as brown rice at ordinary fertilizer level in local adaptability test for three years. Nunkeunheugchal possesses benefits to rice consumers because of high amounts of GABA, anthocyanin, calcium and iron. This variety would be adaptable to the paddy field of middle and southern plain region of Korea.
