In this study, 13 agronomic traits of 160 chickpea germplasm resources induced from ICRISAT were evaluated. The results showed that these chickpea germplasms represented abundant genetic diversity. The variable coefficients of 7 quantitative traits were branches per plant(70.1%)>pods per plant(46.1%) > 100-seed weight(27.5%) > yield(23.7%) > plant height(20.5%) > seeds per pod(18.3%) > growth period(5.8%), and the genetic diversity index of 6 quality traits were seed color(1.385) > plant type(1.119) > flower color(0.905) > seed surface(0.772) > seed shape(0.412) > leaf type(0.000). The cumulative contribution of the top 4 principal factors reached 63.417% in the principal factors analysis, as well as the first principal factor was mainly related to the yield traits and yield; the second principal factor was mainly related to the growth period; the third principal factor was mainly related to the plant height and seed shape. With cluster analysis, 160 chickpea germplasm resources were classified into 3 groups, the group Ⅰ showed the highest plant height, the group Ⅱ showed the highest yield, the group Ⅲ showed the biggest seed. 63 chickpea germplasm resources with elite agronomic traits were screened, which were early maturing, short stem, unbranching, more pods per plant, more seed per pod, large seed and high yield.
