Phenotypic Identification and Evaluation of Soybean Germplasm Resources in Sichuan Province
摘要
Abstract
In order to effectively utilize soybean germplasm resources in Sichuan Province in China.216 soybean germplasm were collected.In this research,12 phenotypic characters of this soybean germplasm resources in Sichuan Province were identified and comprehensively evaluated by correlation analysis,principal component analysis and clustering analysis.Our results showed that the genotypes of soybean collected in Sichuan were rich in genetic diversity.The diversity index of 9 quality traitsrangingfrom0.043 to1.596,whichwas the highest in seed color(1.596)and the lowest in cotyledon color(0.043).3 quantitativetraitsrangingfrom2.581 to2.812,which was the highest in100-seed weight(2.812).Principal component analysis showed that the cumulative contribution rate of the six principal component factors was 72.85%.The comprehensive evaluation D value ranging from 0.002 to 0.278.216 soybean germplasm could be classified into 4 categories by cluster analysis,Cluster Ⅰ showed the best performance in 100-seed weight(31 germplasms).The plant height of cluster Ⅱ was the highest(52 germplasms).Cluster Ⅲ showed the shortest growth period(57 germplasms).The 100-seed weight and plant height of cluster Ⅳ was low(76 germplasms).This study can provide a new reference for the utilization of soybean germplasm and breeding.关键词
