Phenotypic Stability for Fruit Yield in Mango (Mangifera Indica L.)
Year: 1985
Type: article
Abstract: Thirty nine varieties of mango (Mangifera indica L.) were evaluated for stability of performance for fruit yield over a period of five years. Genotype-environment interaction was present; a large portion of this interaction could be accounted for the linear regression on the environment. Though non-linear component was also present, its magnitude was considerably smaller than that of the linear component. A simultaneous consideration of the three stability parameters i.e., yi, bi and S2di for individual variety indicated that variety ‘Rumani’ possessed high yield (Yi = 96.95 kg/tree) with a linear response and negligible deviation from regression and was found to be most stable. The highest yielding variety ‘Suvarna Jahangir’ (Yi = 114.60 kg/tree) was highly responsive to the favourable environments (bi = 4.38) and was characterised as most unstable.
