- 摘要:
- 以32份毛酸浆种质资源为试验材料，采用相关性分析、主成分分析、聚类分析等方法对毛酸浆18个农艺性状进行鉴定分析和综合评价，研究了毛酸浆种质资源的遗传多样性，以期为后续遗传育种提供参考依据。结果表明:32份毛酸浆种质资源的农艺表现类型丰富，7个数量性状的变异系数在18.45%~33.83%，遗传多样性指数大小在1.397~2.043，材料的多样性较为丰富，遗传差异较大。相关性分析结果显示，18个农艺性状之间相关性复杂，大部分农艺性状之间表现出显著的相关性。聚类分析和主成分分析表明，当欧式距离为10时，可将材料分为4类。其中第一类材料P32（野生黄菇娘）综合表现优良。
- Abstract:
- Taking 32 germplasm resources of Physalis pubescens as the test materials,correlation analysis,principal component analysis and cluster analysis were used to identify and comprehensively evaluate 18 agronomic traits of Physalis pubescens.The genetic diversity of Physalis pubescens germplasm resources was studied,in order to provide references for subsequent genetic breeding of Physalis pubescens.The results showed that the agronomic performance types of 32 Physalis pubescens germplasm resources were rich,the coefficient of variation of 7 quantitative traits was 18.45%-33.83%,and the genetic diversity index was 1.397-2.043.The diversity of materials was rich and the genetic difference was large.The results of correlation analysis showed that the correlation between 18 agronomic traits was complex,and most of the agronomic traits showed significant correlation.Cluster analysis and principal component analysis showed that when the euclidean distance was 10,the materials could be divided into 4 categories.Among them,the first type of material P32(wild mushroom) had excellent comprehensive performance.
