| Abstract: | 【Objective】This paper aims to study the correlation between the yield of the main soybean cultivars of earlier - maturing soybean varieties in Xinjiang,and their yield traits so as to provide a reference index for breeding or improving new varieties.【Method】The yield and agronomic characters of 16 soybean varieties were analyzed by using the grey relational grade analysis methods.【Result】The results showed that major agronomic characters related to yield were in following sequence:seed weight per plant > plant height > seed number per plant > pod number per plant > effective branch number > height of lowest pod > main stem node > 100 -seed weight number.【Conclusion】The result has practical significance for setting the goals of breeding or improving soybean varieties. |
