The Selection Effectiveness of Various Forms of Sugar Beet in Early Ontogenesis
The selection of cold-tolerant forms was carried out during seed germination at a temperature of 90C. Root material was grown in flowerpots, seeds were obtained by self-pollination in individual isolators. After repeated selections, the combining ability of the most valuable forms was studied as the parent components of the cross when creating new hybrids. The offspring of genotypes selected with the help of a cold background exceeded the control on the basis of germination and length of the seedling. The effectiveness of such studies is shown by the example of new hybrids Azimut, Kuban MS-95, and Uspekh.
