Phenotypic stability for fruit yield and its components in rainy season brinjal (Solanum melongena L.)of Chhattisgarh plains

Abstract

Seven open pollinated genotypes of long brinjal were evaluated in three environments under rainy season and irrigated situationsfor Chhattisgarh plains. Data analyzed for stability parameters and highly significant mean squares were observed forgenotypes, genotype x environment interaction and environment (linear). IBWl-2007-1 was the most stable genotype underirrigated condition of Chhattisgarh plains for kharif planting situations as it had high mean, regression coefficient not deviatedfrom unity and non significant deviation from regression. Whereas, a local genotypes was suitable for fruit yield under lowyielding environment.
