Alternativas de consideração da paternidade na avaliação genética de rainhas Apis mellifera L. (Hymenoptera: Apidae) africanizadas

Abstract

This study aimed to estimate genetic parameters for weight Apis mellifera Africanized queens emergency assuming the drone of information in the pedigree as known group of parents ghosts and unknown. The database comes from a selected population for five generations to weight the emergency. Bayesian inference was used for the estimation of genetic parameters, via MTGSAN program. The greater weight of the heritability values were obtained when the emergence was assumed paternity information as ghosts parent groups (0.50), followed by unknown parents (0.38) and known (0,29). The coefficients of variation regarding the additive genetic variance were similar in the different forms of paternity account in the pedigree, but was lower (23,95) when considering the parents information as unknown, followed by ghosts parents (24.79) and known parents (27.77). Thus, the method was considered better then ghosts parent groups, for this alternative the consideration showed a higher proportion of identified additive variance and coefficient of variation similar to the use of unknown parents and lower when compared to use of known parent .
