Purpose. The aim of our study was to determine the combination ability of the studied pollinators and identify the genetic control of the yield sign in interline diallel hybrids of sugar beet.
Methods. The source material was homozygous as a result self-pollination. The combination ability and genetic control of quantitative traits were determined by the Hayman model.
Results. Genetic analysis revealed that sugar beet pollinator line demonstrated genetic control of yield in diallel sugar beet hybrids by 14 genes and gene groups. Lines (BZ 1 and BZ 4) with high general combination ability demonstrated a significant additive effect of genes were selected. The effects of specific combination ability, which significantly affected the yield of heterosis hybrids, were revealed. Their share of influence was 36.4 and 23.8%, respectively. High-yielding hybrid combinations of parent genotypes were selected. They are transferred to reproduction and testing for ecological plasticity.
Conclusions. Genetic control of the yield sign in diallel hybrids is found based on the Hаyman model. The influence of the combination ability of sugar beet pollinators was determined and the best parent genotype pairs were selected. According to the effects of specific gene interaction, the best combinations have been identified that can be used as sources of economically valuable traits.
