초록
대두 종자크기에 대한 간접적인 선발형질로써 잎크기에 대한 이용 가능성을 알기 위하여 종자크기에 있어서 큰 차이를 보이는 12개의 line을 선발하여 2년간 포장시험을 실시하였다. 종자크기와 잎크기의 차이에 있어서 고도의 유의성을 나타내었고 개화전 종자크기에 대한 간접선발로써 잎크기의 이용성이 가능할 것으로 보였다.
The objective of this research was to determine if leaf size (width and length) is correlated with seed size to the extent that leaf size can be used as a predictor of seed size in a population of soybean plants or lines. Twelve soybean strains, representing three distinct seed size groups, were analyzed. Data on seed size and leaf size of the 12 strains were obtained in 1994 and 1995 field experiments. Strain seed size was positively associated with leaf width (r=0.918) and leaf length (r=0.925). The results of our study indicate that there is a significant correlation between seed size and leaf size in soybean. It is possible that selection for greater seed size either leads to, or results from, greater leaf size.
