以中国花生种质资源数据库中记录的6390份花生资源为材料,以其基本数据、特征数据和评价数据为信息,采用分层分组聚类以及随机取样与必选资源相结合的方法,构建了由576份资源组成的花生核心种质,占基础收集品的9.01%。除出仁率外,核心种质与基础收集品种间的其他14个性状平均值和多样性指数差异均不明显,表明本研究建立的核心种质是有效的。与ICRISAT花生微核心种质的比较,中国花生资源在龙生型和珍珠豆型方面具有优势,叶片长、叶片宽、种子长、种子宽的遗传多样性丰富;而ICRISAT花生资源在多粒型和普通型方面具有优势,且植株高度和总分枝数的遗传多样性比中国花生资源丰富。
Based on the data of 6390 peanut resources recorded in China Peanut Germplasm Resource Database, using the basic data, characteristic data and evaluation data as the information, the method of hierarchical cluster clustering and random sampling combined with the necessary resources was constructed Core peanut germplasm consisting of 576 resources accounted for 9.01% of the total collected. In addition to kernel rate, the average of 14 other traits and the diversity index between the core collection and the basic collection were not significantly different, indicating that the core collection established in this study is effective. Compared with ICRISAT peanut micro-core collection, the peanut resources in China have advantages in both dragon-type and pearl-bean type, and are rich in genetic diversity of long leaves, wide leaves, long seeds and wide seeds; however, And common type, and the genetic diversity of plant height and total number of branches is more abundant than that of Chinese peanut.
