- Abstract:
- All soybean cultivars released in the past 30 years from different ecological regions in Heilongjiang province were analyzed by correlation coefficient and principal component analysis for traits selection.The results showed that it was feasible to select plant height and protein content simultaneously in the first ecological region,100-seed weight,protein content and yield in the second ecological region,plant height and 100-seed weight in the third ecological region,fat content and yield in the fourth,the sixth and the ninth ecological region,100-seed weight and protein content in the eighth ecological region,plant height and fat content in the tenth ecological region,protein content and yield in the eleventh ecological region.Then first three principal components whose accumulative contribution rate varied from 80.12% to 90.77% were selected to evaluate soybean resource in Heilongjiang province.
