摘要: 为探索已收集到的90份山西省地方花生种质资源的利用价值,并从中筛选出优质品种,采用室内测定方法对其进行了蛋白质含量、含油量、油酸、亚油酸含量和油亚比5个品质性状的测定分析,探讨了地方种质资源的品质性状与地理来源、类群间的关系。结果表明,5个品质性状的多样性指数分别为2.04、2.02、2.02、1.99、1.93,表明山西省花生地方种质资源品质性状表现出丰富的遗传多样性,5个品质性状的变异系数分别为0.06、0.09、0.11、0.11、0.23,表明各资源间的品质性状存在着显著的差异,通过聚类分析将90份资源划分为了4个类群。筛选出武乡红花生、临县多粒、永济小蜂腰等优质资源,为山西省地方种质资源合理利用和优质花生新品种选育提供科学理论依据。

Abstract: In order to explore the use values of 90 samples of peanut collected from Shanxi Province and select high-quality varieties, this study measured and analyzed their quality traits in laboratory, including protein content, oil content, content of oleic acid and linoleic acid, and discussed the relationship between the quality traits and geographic origin and different groups. The results showed that the diversity indexes of five quality traits were 2.04, 2.02, 2.02, 1.99, 1.93, indicating that the quality traits of peanut germplasm resources in Shanxi had rich genetic diversity. The coefficient variation of the 5 quality traits were 0.06, 0.09, 0.11, 0.11, 0.23, indicating that there was a significant difference between the quality traits among the resources. The 90 samples were divided into 4 categories by cluster analysis. High-quality resources were screened, for example Wuxiang red peanuts, Linxian multigerm, Yongji small wasp waist. The results provided a scientific theoretical basis for rational utilization of local germplasm resources and breeding of new peanut varieties with high quality in Shanxi Province.
