[Genetic analysis for developmental behavior of honeybee colony's royal jelly production traits in western honeybees].

Analyses of genotypic effects for colony's royal jelly (RJ) yields and RJ in each queen cell as well as acceptances of queen cell cups of three lines of Western honeybees (Apis melliffera Lingistica) were conducted by using a genotypic model for analyzing the genetic and non-genetic effects. Analytis approaches of conventional and conditional variance and correlation were employed to evaluate the developmental behavior of honeybee colony's RJ producing ability. The results indicated that significant variance due to genotypic effect was detected for colony's RJ yields and RJ in each queen cell cup at all stages, while the acceptance of queen cell cups was found variance significantly at 10 stages of its total 11. It meant that the three traits were dominated by genotypic effect. Significant conditional variances were found at some stages when no unconditional one being detected. Correlation analysis between same trait at different stages indicated that the significant coefficients always existed due to genotypic effects for RJ yields and RJ in each queen cell cup. Although the significant coefficients of the acceptance of queen cell cup at different stages were found at most of the stages, the coefficients were not found in come of the stages. These results indicated that the genotypic effects dominated in early stages of colony's RJ yield and RJ in each queen cell cup influencing its late stages in the same way, but the acceptance of queen cells cup was not. The analysis of correlation between different pair of traits showed that the coefficients between colony's RJ yields and RJ in each queen cell cup were significant at all stages, and while the coefficients between colony's RJ yields and the acceptance of queen cell cups were not always significant at all stages. It was because the genotypic effects dominated the former pair of traits had harmonious effects, while the later pair of traits were not.
