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.
