Genetic analysis of royal jelly production and behaviour traits of honeybees
Résumé
To improve their honeybee population, the royal jelly producers focus their selection objectives on both production and colony behaviour traits to maintain a sustainable production. To estimate genetic parameters for all these traits, a dataset from the French royal jelly producers group including records collected from 1,347 colonies was analysed using ReML methodology applied to animal models. Heritability estimates for royal jelly production traits were moderate while estimates for colony behaviour traits (gentleness, nonswarming behaviour, spring development, non-sanitary susceptibility and feed autonomy during hollow of honey flow) ranged from low estimates (0.10±0.10 for non-swarming behaviour) to very high estimates (0.68±0.10 for feed autonomy). Unfortunately, the dataset was too small to obtain reliable estimates for the genetic correlations between production and behaviour traits.
