Genotype × Environment Interaction and Stability Analysis for Grain Yield and Yield Related Traits in Little Millet (Panicum sumatrense L.)

The present study was conducted to evaluate Genotype × Environment interaction and stability analysis for grain yield, its components in 50 little millet genotypes under three environments i.e. Waghai, Vanarasi and Navsari locations (Gujarat, India) in year Kharif-2020. Stability analysis revealed that G x E interaction was significantly differed for all the characters except calcium content (mg/100g) and ash content (mg/100g) indicated that different genotypes reacted differently to different environmental conditions. Estimates of environmental indices indicated that Waghai location was favourable for most of the yield contributing characters along with quality parameters followed by Navsari and Vanarasi. The results of present study revealed that none of the genotypes exhibited average stability for all the characters. Among the genotypes, WV 262, WV 258, WV 256, WV 293 and WV 273 were found average stable over environments for grain yield per plant with one or more yield contributing characters and quality parameters. So, these genotypes may be used in further breeding programme in little millet.
