摘　　要：The researches have been carried out in 2011-2012, in the experimental fields of Yuryev Plant Production Institute Kharkiv, Ukraine. The forms of ＂00＂ type （a low content of erucic acid and glucosinolates） and self-pollinated lines--110M-10, 127M-10, 132M-10 were studied; the forms of＂0＋＂ type--selfed lines 124-10, 221-10, 305-10; the forms of＂＋0＂ type--cultivars Victor, Janus, Emerald; forms of ＂＋＋＂ type--cultivars Fyedorovskiy, Marens, Uspikh, as well as, self-incompatible forms 5C, 15C-10, 32C-10 and the original sterile form of mutant origin were used. Viability in stigmas of the pistil lasted 3-7 days, in the forms of ＂＋0＂, ＂＋＋＂ type, 7-15 days in the cultivars and forms of ＂0＋＂, ＂00＂ type, 14-21 days in the self-incompatible and sterile forms. A fast loss of sensitivity to pollen by pistil＇s stigma was observed in the forms of＂＋0＂ and ＂＋＋＂ types. On the contrary, in self-incompatible and sterile forms was observed a gradual increase of sensitivity of pistil＇s stigma to pollination and then its gradual fall. A maximum of sensitivity of a pistil＇s stigma to pollen in ＂00＂ and ＂0＋＂ forms was on the 3rd-6th day after castration.
