영문 초록

The selected lines in male sterile facilitated recurrent selection population RSPYB 1 of barley were compared to leading variety and analyzed by statistical method. Heading and maturing dates were later compared to leading variety Olbori, but culm length shorter to the variety. In yield components of selected lines in RSPYB 1 popluation, No. of grains per spike and N. of spikes per m² were higher than Olbori, however, 1000-grain weight lower than this variety. From the analysis of selection parameters, the follgwing method was recommended to select high yield lines in RSPYB 1 population. Selection performed by 1000-grain weight is to be effective ways for high yield lines considering in the high heritability and high positive direct effect for grain yield of that trait.
