高粱杂交组合遗传多样性及农艺性状与品质相关性分析
Genetic Diversity of Sorghum bicolor Hybrid Combinations and Correlation Analysis between Agronomic Traits and Quality Traits
摘要
Abstract
To analyze the genetic diversity characteristics of Sorghum bicolor germplasm resources and the genetic correlations among agronomic traits,67 core Sorghum bicolor germplasm materials were used as the experimental materials.Using SPSS 26.0 software,variance coefficient analysis,system-atic clustering analysis(average linkage method),and principal component analysis were conducted on 8 key agronomic traits such as plant height,panicle length,panicle grain weight and 1000-grain weight.Correlation heat maps were used to analyze the strength of correlations among the traits.The results showed that the agronomic traits of the tested materials had rich variations,with the coeffi-cient of variation ranging from 12.3％to 38.7％.Among them,the coefficient of variation of 1000-grain weight was the largest(38.7％),while that of panicle length was the smallest(12.3％).Cluste-ring analysis divided the 67 germplasms into 4 groups.Group Ⅰ was mainly characterized by short plants and large panicles,and Group Ⅳ had the best performance in related traits of grain yield.Prin-cipal component analysis selected 3 core principal components,with a cumulative contribution rate of 76.2％,covering core information such as yield components,plant morphology and panicle traits.关键词
