摘要： 研究了河南省龙生型农家品种的农艺性状和蛋白质、脂肪含量等品质性状的变异规律，并进行了聚类分析。结果表明，河南省龙生型花生品种具有遗传多样性。河南省龙生型花生品种蛋白质和脂肪含量均属平均水平，但平均油酸含量高于平均水平。龙生型花生在中、小果型及单株荚果数、油酸含量方面性状表现突出，具有育种利用价值。南阳花生和柘城麻壳在低蛋白品种选育、东明集小花生及郏县三四粒在食用品质及抗病性方面具有利用潜力。

Abstract: The variation of agronomic traits and quality traits in local varieties of Henan dragon peanut were in- vestigated, and the cluster analysis was conducted. The result showed that the genetic diversity existed in local varie- ties of Henan dragon peanut. The protein content and oil content were among the average level,while oleic acid con- tent was above the average. The dragon peanut varieties all belonged to medium or small pod size, and had more ad- vantages in pod numbers per plant and oleic acid content,so they had the utility value in variety improvement. The two varieties of Nanyang and Zhecheng Make had the breeding value for low protein content improvement,while the other two varieties of Dongmingji and Jiaxian Sansili had the potential usage value for the improvement of edible quality and disease resistance.

Key words: Arachis hypogaea var. hirsuta, Agronomic traits, Protein content, Oleic acid content
