| Abstract | Two fractions of seeds (4.5 – 5.5 and 3.5 – 4.5 mm) of three forms of sugar beet (F1 – hybrids, MS – male sterile lines, O- types – sterility fixers) were studied in the breeding nursery Uman experimental breeding station. Three-year studies showed that, with almost equal sowing qualities, plants grown from seed fraction 5.5 – 4.5 mm exceeded smaller fraction respectively by 7.1 and 5.2% by weight of 100 seedlings and resistance to black leg of sugar beet, also by 2.3 – 5.4 and 0.7 t/ha of yield of roots and sugar harvest respectively. In the direction of reduction of the accumulation of mass differences of root, forms ranged in such order: O- types, male sterile lines, and by the productivity, strong dependence was not found. | ||
