【摘要】 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。更多还原

【Abstract】 The problem which is simple and effective technique of producing a lot of F₁seeds 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 F₁hybrid 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 producingF₁ seeds was promoted to a new level and experimetal evidences were posed forfurther studies of hybrid cabbage in our country.更多还原
