영문 초록

This study was carried out to examine whether the leaf size is likely to be used as a selection criterion for large seed genotype in soybean (Glycine. max (L.) Merr.) breeding program. Two hundred twenty nine soybean germplasms which had collected in Korea, United States, China and Japan were used in this experiment. The area of unifoliate leaf, middle leaflet of first trifoliate and third trifoliate leaf ranged from 3.2 cm2 to 33.8 cm2, 9.2 to 29.5 cm2, and 7.2 to 58.9 cm2, respectively. One hundred seed weight also showed great variation from 2.7 to 39.0 gram. The average leaf area of unifoliate, middle leaflet of first trifoliate and third trifoliate leaf were 15.7 cm2, 18.1 cm2 and 32.7 cm2, respectively, and that of seed average weight was 17.2 gram per one hundred seed. Significantly positive correlations were observed between seed weight and leaf area of unifoliate (r=0.80**), first trifoliate (r=0.75**) and third trifoliate (r=0.67**), respectively. Both the leaf length and leaf width of unifoliate, middle leaflet of first trifoliate and third trifoliate leaf were significantly positively correlated with seed weight and both the correlations of unifoliate were higher than the other leaves. The correlations of leaf width in soybean leaflet were higher than those of leaf length. Leaf length/width (L/W) ratio of upper leaf was higher than that of lower leaf in the leaf size. Both the leaf area and leaf width of unifoliate leaf are the most suitable predictive characteristics of early selection in related to seed weight for soybean breeding program.
