A new rice variety Manweolbyeo is a japonica type developed by the rice breeding team of Yeongnam Agriculturalivationcondition from the progenies of a single cross of Milyang120/Hwayeongbyeo. The selected line(YR16326-8-3-2) from the prog-enies of it cross was designated Milyang173 in 1998. When the Manweolbyeo was planted on July 10 for the local adaptabilityyield trials, the average yield of Manweolbyeo during last three years was 4.96 ton/ha for milled rice, which was significantlyight,moderately resistant to blast and stripe virus, but susceptible to insect pests. The characteristic of heading times of it was accel-erated in second cropping season at Milyang as a result of exposure to short-day condition during growth, but was delayed in thefirst cropping season of which belongs to long-day condition. And the variety did not show a premature heading on the cultivationshcrop cultivation in the double cropping system at southern part of Korean peninsula.
