In greenhouse experiments (in soil culture) accumulation of selenium by spring rape plants with application of sodium biselenite (50 and 500 mkg of selenium per 1 kg of soil) was studied. Investigation of fatty acid and element composition of seed of this crop is also included into the programme. In experimental variants the amount of selenium in green mass of rape increased up to 466 and 966, in seed - up to 458 and 599 mkg/kg, that is 2,5-5 and 2-3 times. Application of this fertilizer increased the yield of green mass of rape without reducing the output of seed. Fatty acid composition of seed oil did not change, and there was even tendency for its improvement: small reduction of non-saturation at the expense of the increase in total content of linoletic and oleic acids. The used doses of selenium did not affect the ingress of heavy metals into rape seed
