Variability of combinative ability according to the yield of tetraploid pollinators of sugar beet

On basis of analysis of characteristic of effects of main and combinative ability of tetraploid pollinators of breeding of Bila Tserkva.Under the impact of weather and climatic conditions during 2009-2011we have allocate breeding numbers of pollinators and pollen sterile forms namely component of tetraploid hybrids of sugar beet with heightened adaptive capacity.

The best behind adaptive ability appeared MS lines 1433, 1481 and 1482. On basis pollinators 1019 (4х) hybrid combinations are generated stable behind productivity. Tetraploid pollinators 1002 (4х) is a source of lines with high plasticity. It is established, that in structure of variability of productivity for authentic influences to a genotype of fatherly forms and their interactions the greatest part is allocate to conditions of year - 64 %. It speaks that correct use of adaptive hybrids in concrete ecological conditions is necessary.

Key words: combination ability, tetraploid pollinators, adaptive ability, variability.
