- Abstract
Soybean is an important economic crop in the world, which provides plant protein, oil and a variety of active substances beneficial to human health. In order to comprehensively identify the quality characters of soybean resources abundant in China, 16 kinds of seed quality traits of 520 soybean germplasms in Huang-Huai-Hai ecoregion were evaluated in 6 environments across 2 years with reference to the national standard method. The results showed that the genetic variations of the tested seed quality traits were abundant in the soybean germplasms, and the variation coefficients of isoflavone and tocopherol contents were relative high, while the variation coefficients of protein, oil and fatty acid components were relatively low. Meanwhile, there were significant correlations among the 16 seed quality traits. Principal component analysis showed that the 16 quality traits could be attributed to 5 principal components. Based on the results of principal component analysis, 520 germplasms could be divided into 3 categories by cluster analysis with significant differences. Based on the above results and high stability coefficient analysis, 35 germplasms with multiple or single elite seed quality traits were screened out, which provided important resources for genetic improvement of seed quality traits in soybean.
