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.
