Abstract

Twenty chickpea genotypes were tested as independent experiments under rainfed and irrigated conditions during 2013-14 at The University of Agriculture Peshawar. Data was recorded on 16 metric traits viz. number of primary and secondary branches plant-1, pods plant-1, seeds pod-1, seed weight pod-1, 100-grain weight, above ground biomass, seed yield and harvest index. The results of correlation analysis showed that seed yield plant-1 had strong positive genotypic association with pods plant-1, seed weight pod-1, 100 seed weight and biological yield under both production environments and high positive genotypic association with secondary branches plant-1, seeds pod-1, biological yield and harvest index under irrigated condition only. Path coefficient analysis confirmed the true relationship of pods plant-1, seed weight pod-1, under irrigated condition and seed weight pod-1, harvest index and above ground biomass under rainfed condition. Hence, these characters could be used as selection criterion for further improvement in seed yield of chickpea.
