METHOD OF DIRECT GROWING OF SEEDS OF MALE-STERILE SUGAR BEET HYBRIDS

摘要

A method of direct growing of seeds of male-sterile sugar beet hybrids such that seed fields are placed in climatic zones, where the probability of destroying the direct-sown seed fields by frost at the level of a head of the roots is 0-1 times in the course of 10 years, the direct-sowing seed fields are placed after a fallow, sowing of crossing components is carried out by alternating bands with narrowed joint interrows, a distance between which is of 45-70 cm, for the final density expressed as 5-6 plants per 1 m of a row, and a width of an interrow of a male-sterile component is of 45 cm, a pollinator 70 cm, an additional pollination in the flowering period for the seeds of the pollinator is carried out three times: first while flowering of 20-30%, second of 40-50%, and third while flowering of 60-70%.
