영문 초록

The study was carried out to compare the pedigree, bulk and single seed descent(SSD) methods in rice breeding. Three selection methods were applied from F₂ to F₅ generations of the cross between line 3377 and Gayabyeo. Yield and yield components of the F₆ lines bred by the three methods were compared. No differences in numbers of panicles per hill, numbers of florets per panicle and 1,000 grain weight of the lines from pedigree and SSD methods were found, however, the three components were lower in bulk method than in pedigree and SSD methods. There was no difference in percent of filled grains in the three methods. Grain yields from pedigree and SSD methods were higher than that from bulk method, and no difference was found in the lines from pedigree and SSD methods.
