- Abstract
【Objective】 To understand the genetic diversity and adaptability of introduced soybean germplasm resources from different countries in the hope of providing excellent parents for soybean breeding.【Method】 SPSS 17.0 software and R language software were used for descriptive statistics, correlation analysis, principal component analysis and cluster analysis, and the adaptability and genetic diversity of 417 soybean germplasm resources introduced at home and abroad were analyzed.【Result】 The results showed that 363 of the 417 soybean germplasm resources were able to mature normally in the central Gansu Province, with the highest yield of 3,901.65 kg/hm2 and the highest 100-seed weight of 42.71 g. The genetic diversity index of 16 phenotypic traits ranged from 0.084,2 to 1.916,0, and the coefficient of variation ranged from 18.17% to 35.70%. The phenotypic traits (except for cotyledon color) exhibited varying degrees of correlation. Through cluster analysis, 363 germplasms were divided into 8 groups, and the similarity coefficient of soybean germplasm in Gansu Province was similar to that in Northern China and Huanghuai.【Conclusion】 These soybean resources showed very rich polymorphisms and high genetic diversity, and 26 specific germplasm resources were preliminarily screened.
