摘　　要：为明确鹰嘴豆种质资源在农牧业交错区生态适应性的差异,试验引进129份种质资源,通过对种质资源17个主要农艺性状进行聚类分析、主成分分析以及遗传多样性分析。结果表明:129份材料表现出广泛的遗传多样性,17个主要农艺性状中单荚粒数的遗传多样性指数最高,产量次之;单株粒重的变异系数最大,其次是单株荚数,荚长最小;通过对17个主要农艺性状进行聚类分析得出,129份鹰嘴豆种质划分为5大类群。第1大类可作为选育高产且株高较高的鹰嘴豆种质资源;第2大类能作为选育矮秆及特异粒色;第3大类丰产性较差可作为选育高秆大粒型适宜机械收获的品种;第4大类能够作为选育矮秆小粒型的种质资源;第5大类的鹰嘴豆能够作为选育高产高秆适合机械收获的种质资源。10个主要数量性状的主成分分析结果表明:前6个主成分累计贡献率达87.80%,各主成分的特征值表明主要数量性状的育种方向具有多样性。In order to detemline the ecological adaptability of chickpea germplasm resources in agriculture and animal husbandry, the 17 main agronomic traits of 129 chickpea germplasnl resources were analyzed by cluster analysis, principal component analysis and genetic diversity. The results indicated extensive genetic diversity in the test materials. The highest genetic diversity index was the single pod number, followed by the yield. The coefficient of variation of single grain weight was the largest, tollowed by single pod number and smallest pod length. Through cluster analysis of 17 main agronomic traits the 129 chickpeas were divided into 5 groups. The first group was for breeding of high yield and high plant height varieties; and the second group was tor breeding dwarfing and specific grain color varieties. Although the output of the third group was poor, it could be used as the eultivars with high height and large grain size. The tbmlh group was used as the material of the eultivars with low height and small grain size, while the fifth group can be used as the eultivars of high yield and high lever for mechanical harvest. The resuhs of principal component analysis of 10 quantitative traits showed tha the accumulated contribution rate of the first six principal components was 87.80% , while the characteristic values of the principal components indicated that the breeding direction of the main quantitative traits was diverse.
