Abstract: 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.
