Abstract
The genetic variation,correlation and principal component of 12 agronomic characters of 11 soybean varieties of south group A in Huanghuaihai region were analyzed.The results showed that the variations of No.of branches per plant,lodging scale and pods per plant were the greatest,with a value of 60.93%,34.40% and 27.89%,and variations of growth period were the least,with a value of 4.17%.Correlation analysis indicated that there was a significantly positive correlation between yield per plot and seed weight per plant,and there was also a positive correlation tends among plant height,pods per plant,No.of seeds per plant,seeds per pod and yield per plot.Principal component analysis showed that the first four principal components accounted for 92.16% of total variation.It is very important to select these agronomic traits which have bigger variant coefficient and have high yield.The variety should choose seed weight per plant,pods per plant,No.of seeds per plant and seeds per pod all on high level.
