摘　　要：为了选育优质、较耐低温冷(冻)的油菜不育系,现以两系隐性核育黄籽双低材料1927A为母本,以含油量较高的两系隐性核不育双低材料237B为父本,采用测交、系统选育的方法,转育而成稳定的黄籽双低高油份不育系1923AB。不育系1923AB具有黄籽、品质双低(芥酸0.32%,硫苷20.3μmol·g-1)、含油量高(平均含油率46.5%)、较耐低温冷(冻)等特点。与恢复系18R选配的组合福油508于2011年11月通过国家上游区试审定。To breeding quality, more resistant to low temperature cold （frozen）, rapeseed CMS, now two-line hidden nuclear fertility yellow seed and double low 1927A as the female parent, two-line higher oil content recessive GMS duallow material of the 237B parent test cross, system selection, turn sterile made stable yellow seed and double low high oil sterile line 1923AB. CMS Line 1923AB with yellow seed quality dual low （erncic acid 0.32%, glucosinolate 20.3μmol·g-l）, high oil content （average oil content of 46.5%）, more resistant to cold cryogenic （frozen）. 18R optional combination of blessing oil and restorer lines 508 in November 2011 through the upstream region of test validation.
