영문 초록

One thousand grain weight were investigated for eight plant types classified by branching habit, capsules per axil, and loculi of a capsule. Two typical cultivars were chosen for plant type among 527 gene pools. The order of 1,000-grain weights were arranged from high to low;lower part, main stem and center capsules appeared heavier than upper part, branch and side capsules. Mono capsule setting and unbranched plant type were heavier for grain weight than tricapsule setting and branched type due to inactive ripenness on branched capsules. NMB type showed the heaviest grain weight and thought that BTB type would be the best possibility in yield capacity due to it’s largest sink capacity despite it’s relatively lighter grain weight. NTQ type appeared poor ripenness because of immaturity of higher part side capsules;however, it was believed that there were still possibilities for improving ripeness by enlarge source in 3 capsule and 4 carpels 8 loculi type by the good ripenness of 1 capsule and 4 carpels 8 loculi type. Relationship between grain filling rate and 1,000-grain weight were positive and high(R=0.977**). The grain filling rate appeared to be the most effective component on grain yield among the growth and yield components by path coefficient analysis.
