榨菜胞质雄性不育系(简称CMS)群体中,发现有两种类型的雄蕊:无正常花药结构,整个雄蕊呈丝状或瓣状;有花药结构、花药瘦弱、花粉无生活力。雄性器官分别在两个时期败育:孢子体时期和配子体时期,雄性不育率和不育度均达到100%。此外,雄性不育性世代稳定。CMS植株中大约90%具有正常雄蕊,人工授粉后平均每角果结籽146粒,超过其相应保持系12粒;不育系中10%的植株雌蕊部分不育;不育系在自然授粉情况下,CMS单株种子产量可达72g,比保持系高166%。同时CMS具有良好的经济性状,接近其保持系T84-66。可望利用其生产F1种子
Tuber mustard cytoplasmic male sterile line (referred CMS) groups, found that there are two types of stamens: no normal anther structure, the entire stamens filamentous or petal; anther structure, anther emaciated, pollen no viability. Male organs were aborted in two periods respectively: the sporophyte period and gametophyte period, the male sterility rate and the sterility reached 100%. In addition, male sterility is stable from generation to generation. Approximately 90% of the CMS plants had normal stamens. After artificial pollination, the average number of seeds per plant was 14.6, which exceeded the corresponding maintainer line by 1.2%. The pistils of 10% of the male sterile lines were partially sterile. The male sterile lines In the case of natural pollination, CMS seed yield per plant up to 7 2g, 16 6% higher than the maintainer. At the same time CMS has a good economic traits, close to its maintenance department T84-66. It is expected to be used to produce F1 seeds
