Abstract:

Twenty-eight soybean mainly cultivated varieties in the central and eastern of Heilongjiang province were used as materials, the analytical methods of the principal component analysis, membership function method, and stepwise regression analysis had been used to evaluate the yield and to select the determination of evaluation indicators. The results showed that ten single yield indexes were being transformed to four independent comprehensive components through principal component analysis representing 79.083% cumulative contribution rate. The membership function method was employed to calculate the comprehensive yield value (Y). After the yield comprehensive evaluation, high-yield soybean varieties Henong 71, Henong 85, Suinong 26, Henong 75, Heinong 61 and Henong 76 were screened out. A mathematical evaluation model for soybean yield was established by stepwise regression analysis, Y=0.122+0.736X1+0.465X2+0.168X3+2.527X4+0.326X5+0.289X6-0.313X8, which mean accuracy was 92.16%. Seven indexes were closely related to the yield, including the nodes on the main stem, pod number per plant, seed number per plant, seed number per pod, seed weight per plant, 100-seed weight, and four-seed pod number. The model can be used as a theoretical basis for yield evaluation of soybean breeding materials and variety yield identification.

Key words: The central and eastern of Heilongjiang province, Soybean mainly cultivated varieties, Yield evaluation, Evaluation indicators
