'Jungmo1045', a multi-resistant japonica rice cultivar developed from a cross between 'Hanggeumnuri' having a good eating-quality and high yield and 'SR30071' having brown planthopper (BPH) resistance, was developed by the rice breeding team of NICS, RDA in 2015. This cultivar has about 121 days growth duration from transplanting to harvesting in west-southern coast, Honam and Youngnam plain of Korea. It has 73cm culm length and 22cm panicle length. In reaction to biotic and abiotic stresses, it shows resistance to bacterial blight pathogen races from K1 to K3, stripe virus and brown planthopper. The milled rice of 'Jungmo1045' exhibits translucent, relatively clear non-glutinous endosperm and medium short grain. It has good palatability of cooked rice compared with 'Nampyeongbyeo'. The milled rice yield performance of this variety is about 5.74 MT/ha in local adaptability test for three years. 'Junngmo1045' would be useful genetic resources for multi-resistance breeding program against disease and insect and eco-friendly cultivation.
