Abstract:
Background: Yield is polygenically inherited and highly influenced by G x E interaction higher magnitude of G x E interaction among genotypes invalidates the fitness of genotypes across the environments. Hence, quantification G x E interaction and identification of stable genotypes across environments will enhance production and productivity of pigeonpea.
Methods: The stable performance of the thirty three advanced medium duration lines of pigeonpea along with six check varieties across the seasons were examined during kharif-2017, 2018 and 2019 at Zonal Agricultural Research Station, (ZARS) Kalaburagi, Karnataka, India. The advanced medium duration genotypes was contributed by six research stations belongs six states in India. Result: Considering all stability parameters the genotype ICPL 20108 found stable, high yielding and had desirable agronomic traits. The genotype GRG 177 though ranked first for mean yield, it exhibited nonlinear regression indicating highly sensitiveness to different environments. The genotype GRG 152 had second highest mean yield with bi less than 1 (bi= regression) and non significant deviation from regression co-efficient indicating its specific suitability to unfavorable/poor/low input environments. The genotypes BDN-2014-1, ICPL 20098 and AGL-1603-4 had average yield above population mean and exhibited stable performance across environments.
