Abstract
The present experiment was conducted to analyze G × E interaction and characterization of twelve chickpea genotypes of diverse origin during three consecutive years with three replications under rice fallow land. Plot yield was negatively associated with dry root rot (-0.66*) and stunt disease (-0.53*). Based on mean yield performance, GCP 105 (2771.11 g) produced highest yield over environment followed by JG 14 (2744.44 g) and DCP 92-3 (2716.67 g). Based on ranking using plot yield regression coefficient, Shubhra was found stable genotypes followed by Rajas and JG – 11 however Pant G186 was found more stable in reference to mean square deviation from regression followed by Shubhra and BG 372. The genotypes BG 372, Pant G 186, GCP 105 and DCP 92-3 had regression coefficient (bi) greater than one and mean value more than their population mean for plot yield and minimum incidence of DRR and stunt disease. So, our recommendation would be to promote genotypes, i.e. BG 372, Pant G 186, GCP 105 and DCP 92-3, under rice fallow areas of Bihar state.
