西北干旱半干旱区豌豆种质资源农艺性状的遗传多样性分析
Genetic Diversity Analysis of Agronomic Traits in Pea Germplasm Resources in the Arid and Semi-arid Regions of Northwest China
摘要
Abstract
This study aimed to introduce excellent genes from different genetic backgrounds for pea breeding in the arid and semi-arid regions of Northwest China,thereby improving breeding levels and providing varietal support for pea production.To assess the genetic diversity of agronomic traits in 50 pea germplasm resources from different regions,Shannon-Wiener's diversity index and SPSS 21.0 software were used to analyze the genetic diversity index,coefficient of variation,correlation analysis,principal component analysis,and cluster analysis of 19 agronomic traits.Results showed that plant grain weight and hundred-grain weight had the highest genetic diversity index(3.912),while seed color had the highest coefficient of variation(46.70%).Correlation analysis showed that there was a correlation among the 13 quantitative traits with some showing highly significant correlations.Principal component analysis reduced the 13 agronomic quantitative traits of the 50 pea germplasm resources into 4 principal components,with a cumulative contribution rate of 77.873%.At an Euclidean distance of 4,the tested pea germplasm resources were classified into 5 groups,each possessing specific trait advantages.关键词
