Abstract:
Two soybean cultivars,‘Jinda 52’，‘Jinda 57’，and their filial generations were selected as tested materials to study genetic relationship of 15 agronomic characters including plant height，branch number，growth stage, yield，etc.Fifteen indicators could be integrated into six new indicators with the cumulative contribution rate of 85.81% by principal component analysis.The regression equation between yield and values of the principal components was acquired by multiple linear regression.The absolute values of error of varieties were below 10% except 6 lines by forecast of yield from regression equation.Fifty-seven lines were classified into three yield groups by cluster analysis.Results suggest that principal component regression could be used for study on the biological characters associated with yield.Indicators including total pod number，total seed number，pods of main stem，branch number and chlorophyll content had great influence on seed yield，and soybean yield potential could be predicted via research on distinct levels between different characters.
