Some male sterile plants were found in a seed field of the carrot variety "Imperator." The male sterile flowers were characterized by shortened stamens and shrivelled anthers adhering to the surface of the pistil. Male-sterile, partially male-sterile and male-fertile plants were obtained from progenies of open-pollinated male sterile plants. Partially male-sterile plants have some flowers in individual, umbel with normally or poorly developed anthers and normal or aborted...

Some male sterile plants were found in a seed field of the carrot variety "Imperator." The male sterile flowers were characterized by shortened stamens and shrivelled anthers adhering to the surface of the pistil. Male-sterile, partially male-sterile and male-fertile plants were obtained from progenies of open-pollinated male sterile plants. Partially male-sterile plants have some flowers in individual, umbel with normally or poorly developed anthers and normal or aborted pollen grains. Preliminary data suggested that male-sterility from this source might be used for breeding male sterile lines, for the ultimate production of hybrid carrot seed.

在胡萝卜种株内检查出雄性不孕植株。雄性不孕花表现雄蕊花丝不伸长,花药萎缩而呈黄褐色。雄性不孕植株自然杂交后代,出现完全雄性不孕、部分雄性不孕与正常孕性植株。初步认为,检查出来的雄性不孕植株,可进一步培育胡萝卜雄性不孕系,生产一代杂种。

A group of Chinese cabbages (B. Pekinensis Rupr.)of male sterile AB line was obtained by selecting male sterile plants from natural population or self-pollinated progeny and by transferring sterility of an undesirable line to a local desirable line. Sterility is controlled by a pair of recessive gene. Sterile genes are different from each other among sterile lines derived from different sources.

A group of Chinese cabbages (B. Pekinensis Rupr.)of male sterile AB line was obtained by selecting male sterile plants from natural population or self-pollinated progeny and by transferring sterility of an undesirable line to a local desirable line. Sterility is controlled by a pair of recessive gene. Sterile genes are different from each other among sterile lines derived from different sources. According to the fact that in each generation of male sterile AB line, 50% sterile plants and 50% heterozygous fertile plants are segregated, stock seeds could be retained by sib-mating of the same line; by establishing every other rows with a ratio of 3 sterile lines to one pollen parent and roguing fertile plants from the rows of female parents during early flowering period F1 hybrid will thus be produced. In practice, it is demonstrated that this method of producing Chinese cabbage F1 hybrid by male sterile AB line has many advantages, e. g. making stock seed propagation easy, ensuring the quality of produced hybrid seeds and their parents being not easy to degenerate.

研究证明,自然界存在的大白菜雄性不育材料的不育性,大都受细胞核内的隐性基因所控制。基因的对数一般很少,多数仅一对。不同雄性不育系的不育基因往往不相同,如“127”系受ms_1控制,72011系受ms_2控制。不同不育系不育花雄蕊的外形也有明显的差异。 利用在大白菜自然群体中或自交后代中寻找天然雄性不育株,和利用人工转育的方法均能有效地选育出雄性不育两用系。大白菜雄性不育两用系原种可在隔离区内靠昆虫授粉繁殖。利用它与父本系3∶1隔行定植,在初花期拔除母本行可育株,即可获得高纯度的一代杂种种子。

The problem which is simple and effective technique of producing a lot of F_1seeds should be solved firstly.It is especially conducive to the utilization and po-pttlarization in a large area of hybrid vigor which exist generally in the chineseeabbage.“Ai jiao Huang”of male sterile AB Line NO.3 and NO.8had been bredout,the system of producing the F_1hybrid seeds by the AB Line was established andthe genetic type of male sterile was determined in our experiment. We have sol-ved the technique of producing the seeds of the better hybridized combination ofchinese cabbage“Dwarf Hybrid NO.1”.It was rapidly popularized in the country-side of Nanjing and other regions.This variety of chinese cabbage meets the re-quirment of short season in summer.At the same time,technique of producingF_1 seeds was promoted to a new level and experimetal evidences were posed forfurther studies of hybrid cabbage in our country.

为使普遍存在于白菜的杂种优势能够大面积利用推广,必须首先解决杂种一代的简易而有效的大量制种技术问题。本试验矮脚黄雄性不育两用系 AB 矮3与 AB 矮8的育成,利用两用系制种技术规程的制订以及核质型雄性不育遗传机制的确定。不但解决了我们育成的火白菜优良杂交组合“矮杂一号”的制种技术,使其在南京市郊区及其他地区得以迅速的大面积推广,并且在“堵伏缺”中发挥了重要的作用。同时,也把我国白菜的一代杂种制种技术提高到一个新的水平,为我国白菜杂优化工作的开展提供实验依据。
