Abstract

Phenotypic and genetic variance components for mango (Mangifera indica) traits were estimated. The analyzed population composed of 745 progeny derived from both controlled crosses and open pollination. The average percent of selfing was estimated from the statistical model to be 50%. Both the additive and the dominance (non-additive) genetic variance components were calculated. In all 13 traits analyzed, the additive genetic variance components were not statistically significant while in eight of the traits the dominance genetic variance was significant. In three pairs of traits, significant phenotypic correlation was detected and in one pair of traits, significant genetic correlation was found. Conclusions for mango breeders are discussed with the main recommendation being to widen the genetic background of the breeding population.
