13. Interrelationships among yield and yield components in chickpea (Cicer arietinum L.) under irrigated and rainfed conditions
Main Article Content
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.
