本研究从中国高芥酸甘蓝型油菜品种华油8号与加拿大无芥酸品种Altex杂交的后代中,分离和鉴定出了两种不同的纯合中芥酸基因型,它们在一个基因座位上具有纯合的有芥酸基因E.在另一座位上具有纯合的无芥酸基因c,其基因型组成可分别用E_AE_Ae_Ce_C和e_Ae_AE_CE_C表示。二者的芥酸含量均为27%左右,基本上等于双亲的平均值。这两种基因型的杂交后代和回交后代的分离结果表明,其遗传行为与无芥酸和高芥酸杂交后代的结果相同,这再次证实了芥酸的遗传假说,同时也证实了这两种基因型的遗传组成。文后讨论了这两种基因型的可能用途。
In this study, two different homozygous erucic genotypes were isolated and identified from the offspring of Chinese high erucic acid (Brassica napus L.) varieties HuaYu 8 and Canadian erucic acid variety Altex. They were found in one locus Has a homozygous erucic acid E. In another locus has a homozygous erucic acid-free gene c whose genomic composition can be represented by E_AE_Ae_Ce_C and e_Ae_AE_CE_C, respectively. Erucic acid content of both are about 27%, basically equal to the average of the parents. The segregation of the progeny and backcross progeny of the two genotypes showed that the genetic behavior was identical to that of the non-erucic acid and high erucic acid crossed progenies, again confirming the genetic hypothesis of erucic acid and confirming both The genetic composition of the genotypes. The text discusses the possible uses of these two genotypes.
