The content of erucic,eicosenoic,oleic,linoleic and linolenic acidsin seed from a cross of rapeseed (Brassica napus L.) was quantita-tively determined by gas chromotography to study the inheritance andcorrelations of these fatty acids.It has been showed that both erucicand eicosenoic acid content of seed oil were controlled by the genotypeof the embryo,and two gene pairs which acted in additive manner,governed the inheritance of erucic acid content,and that each allelecontributed approximately 12~14% erucic...
