Abstract:
In order to screen and identify of soybean varieties suitable for intercropping with maize in Yunnan province,this study used the grey relational degree and system cluster analysis method, ten agronomic and yield characters of 44 soybean varieties (lines) conducted a comprehensive analysis and evaluation under the conditions of corn and soybean intercropping. The results showed that the coefficient of variation in phenotypic traits was between 7.3%-51.2%，which illustrated that the germplasm from around had a relatively rich morphological diversity. Using grey correlation degree analysis indicated the order of main characters which influenced the yield of intercropping soybean as follows: seeds per plan, Number of nodes on main stem, 100-seed weight, Pods per plant, number of branches, lodging resistance, plant height, Internode length, and seeds per pod. By the system cluster analysis of 44 soybean varieties was classified into three clusters. More pods per plant, more seeds per plant, more branch and moderate 100-seed weight of the first class were suitable for intercropping with corn in Yunnan province.
