以芥菜型油菜（Brassica juncea）胞质雄性不育系欧新A为不育胞质供体，以菜用芥菜中笋子芥（B．juncea var．crassicaulis）、茎瘤芥（B．juncea var．tumida）和大头芥（B．juncea megarrhiza）为受体，通过杂交和连续回交育成了莱用芥菜三个变种的胞质雄性不育系。每世代全部植株的花器结构均具有典型的雄不育特征，表现为雄蕊增长、柱头突出蕾外。不育系蜜腺发育良好，大而浓绿，在蕾期和花期间存在明显的“突柱期”。初花期比保持系推迟3～7天，整个花期延长1～3天。其雌蕊育性正常，人工授粉后平均单荚结籽15．6粒，比保持系多1．2粒。不育系花粉败育，无生活力花粉94％以上，不育株率100％，不育性世代稳定。
The male sterile line of Brassica juncea, Ou Xin A, is a donor of sterile cytoplasm. The B. juncea var. Crassicaulis, B. juncea var. .tumida) and B.juncea megarrhiza were used as recipients. Three lines of Brassica juncea cytoplasmic male sterile lines were crossed and crossed back. The floral structure of all plants in each generation has the typical characteristics of male sterility, showing the growth of stamens, stigma prominent bud outside. Male sterile nectary system developed well, large and dark green, there is a clear “column period” during the bud and flowering period. The initial flowering than the Department of postponed 3 to 7 days, the entire flowering extended 1 to 3 days. The pistil fertility normal, artificial pollination after an average of 15.6 single pod seed, maintaining more than 1.2 lines. Pollen abortion in sterile lines, non-viable pollen more than 94%, infertility plant rate of 100%, sterile generation stable.
