摘　　要：对蚕豆种质资源籽粒表型和营养品质性状的多样性进行评价,为中国蚕豆种质资源创新和品质育种提供参考。对55份蚕豆种质资源的6个籽粒表型性状和6个营养品质性状进行相关性分析、主成分分析和聚类分析。结果显示,籽粒表型性状变异系数为2.44%~32.94%,遗传多样性指数为1.861~2.046;营养品质性状变异系数为3.91%~44.22%,遗传多样性指数为1.174~2.038。相关性分析结果表明,籽粒营养品质性状与表型性状之间存在关联,蛋白质含量与粒宽、籽粒周长、籽粒表面积呈显著正相关,淀粉含量与粒长、粒宽、籽粒周长、籽粒表面积和百粒质量呈极显著负相关。前4个主成分的累计贡献率为78.152%,其中,第1主成分主要由籽粒表面积、粒长、籽粒周长、粒宽、百粒质量等性状决定,第2主成分主要由籽粒长宽比和单宁含量决定,第3主成分主要由淀粉含量和粗纤维含量决定,第4主成分主要由脂肪含量和蛋白质含量决定。通过聚类分析,将55份蚕豆资源分为5个类群,第Ⅰ类群为低淀粉含量、低脂肪含量、低纤维含量的中粒材料;第Ⅱ类群为高蛋白质含量、高脂肪含量的大粒优异材料;第Ⅲ类群为高单宁含量的大粒特异材料;第Ⅳ类群为高淀粉含量、高粗纤维含量、低单宁含量的中粒优异材料;第Ⅴ类群为低水分含量的小粒材料。Genetic diversities of seed phenotypic traits and nutrient quality-related traits of faba bean germplasm resources were evaluated to provide reference for the innovation of faba bean germplasm resources and quality breeding in China.Correlation analysis,principal component analysis and cluster analysis of six seed phenotypic traits and six nutrient quality-related traits of 55 faba bean germplasm resources were conducted.The results demonstrated that,the variable coefficients of seed phenotypic traits were 2.44%-32.94%,and the genetic diversity indices were 1.861-2.046.The variable coefficients of nutrient quality-related traits were 3.91%-44.22%,and the genetic diversity indices were 1.174-2.038.Results of correlation analysis showed that,relevance was observed between seed nutrient quality-related phenotypic traits and phenotypic traits.Seed protein content was in significant positive correlation with seed width,seed perimeter and seed surface area,while starch content was in extremely significant negative correlation with seed length,seed width,seed perimeter,seed surface area and hundred-grain weight.Cumulative contribution rate of the front four main components was 78.152%.The first principal component was mainly determined by traits such as seed surface area,seed length,seed perimeter,seed width and hundred-seed weight.The second principal component was mainly determined by length-width ratio and tannin content of seed.The third principal component was mainly determined by starch content and crude fibre content.The fourth principal component was mainly determined by fat content and protein content.55 faba bean resources were divided into five groups by cluster analysis.Among them,groupⅠbelonged to moderate-sized materials with low contents of starch,fat and crude fibre.GroupⅡbelonged to excellent large-sized materials with high contents of protein and fat.GroupⅢbelonged to special large-sized materials with high tannin content.GroupⅣbelonged to excellent middle-sized materials with high contents of
