The aim of the research was the identification genotypic methods for estimating the value of bee queen improving, by their testing after qualities of descendant. The researches was conducted on the Apis mellifera Carpathian bee families, have been grown at the experimental apiary of the Institute of Zoology of the Academy of Sciences. The apiary is located at stationary in a clearing at the edge of the forest. The main melliferous sources in this area are white acacia, linden and wild flora, inclusive yellow melilot. In these experiments were genotypic tested five bee queens after qualities of descendant. For this, have been formed 5 similar batches of bee families (each10 families in every batch), in which, at one time was changed old queens and implanted queens young - daughters of one of the queens - mothers supposed testing. The value of improvement queens-mothers was assessed by comparison averages method morph- productive characters of daughters bee families with the average for the entire apiary, calculating the absolute and relative difference of the averages for each character (feature) in part. At the daughter’s families were studied following morphs – productive characters: queen prolificacy, family power, resistance to disease, brood viability and honey production. The research results have shown that according of testing 5 queens after qualities descendants, through the method of comparing with average apiary, have been identified 2 queens which improve honey production. After other morph- productive characters studied, the tested queens have a neutral improvement value. At least in the studied population, it was not identified universal - ameliorative queen of all morph - productive characters. Research result have shown, that phenotypic performance of previously selected queens after their qualities and their families-parents, does not guarantee the improvement value without testing them after qualities of descendant.
