Studies on genotypic and phenotypic variability in mango (Mangifera indica L.)
Keywords:Genotype, variability, heritability, genetic advance, mango
Thirty mango genotypes were studied to find out their variability, heritability, and genetic advance. Significant variations were observed in 46 characters. There were also considerable differences between the genotypic and the phenotypic coefficients of variation for almost all the characters which indicated the influence of environment on the expression of these traits. Among the studied characters, GCV and PCV were high for 40 characters. All the characters showed considerably high heritability except leaf width which ranged from 21.32 to 99.85 % and the genetic advance (as % of mean) was high for 44traits. High heritability coupled with high genetic advance was observed in 44 traits except leafwidth and chlorophyll content which indicated that these characters were less influenced by environment confirming predominance of additive gene action and therefore, selection in favour of these 44 characters would be feasible for yield improvement of mango.
