Stability analysis of yield and yield components in chickpea (Cicer arietinum L.) genotypes across three rainfed locations of Pakistan

One approach to improve the chickpea yield is to identify stable genotypes that perform consistently better under diverse environments. fifteen genotypes of chickpea were evaluated for stability of different yield parameters under three diverse environments (bhakkar,chakwal and rawalpindi) in the punjab province of pakistan. variance due to genotypes,environments,genotype x environment and environment (linear) was highly significant for days to flowering,plant height,number of pods per plant,100 grain weight and grain yield per plant across the environments. by using eberhart and russel method of stability analysis genetic differences among diverse cultivars were calculated. the results showed that different genotype depicts significant genotype x environment (linear) response under contrasting conditions. the present study revealed that genotypes 01067,3cc-113 and azc-06 showed stable performance for days to flowering and number of pods per plant. the genotypes cmc211-5 and 3cc-116 depicted stable performance for days to flowering and grain yield per plant. the genotypes bittal-98 was stable for number of pods per plant and grain yield per plant. the genotype ch24100 was stable for days to flowering and 100 grain weight. the genotype dasht with the highest grain yield per plant was found stable for 100 grain weight. the present study concluded that in general the genotypes differed for yield components regarding stability in chickpea.
