[目的]探究甘蓝自交不亲和系繁殖技术。[方法]采用不同的种株越冬方式、处理方式,观察各处理生长情况,考种后统计各处理结籽率,测定种子活力。[结果]在越冬方式中以将种株整株挖起,带土坨栽于日光温室效果最好,其植株高大、生长健壮、有效分枝多、花蕾饱满、产量高,种子千粒重、发芽势、发芽率均有一定程度提高。在种株处理方式中,以前期自然生长,盛花末期打顶效果最好。[结论]不同越冬方式对春魁甘蓝父本繁殖有着较大影响,成株露地越冬适宜于生产上大面积应用,温室越冬可用于原原种、原种繁殖。春魁甘蓝母本种子产量主要还是集中于主枝和一级分枝,二级分枝有一定产量,生产中去三级分枝能明显提高产量和质量。
[Objective] The research aimed to study the breeding technology of self-incompatible lines in cabbage. [Method] The methods of overwintering and treating different kinds of plants were used to observe the growth of each treatment. After the test seeds were collected, the seed yield of each treatment was calculated and the seed vigor was measured. [Result] In the overwintering way, the whole plant was dug up and the soil was planted in sunlight greenhouse. The plant was tall, strong and robust, with many effective branches, full flower buds, high yield, 1000 seeds weight, germination potential , Germination rate have increased to some extent. In the treatment of seed treatment, the early natural growth, the best end of full-flowering topping. [Conclusion] Different methods of overwintering had a great influence on the parental breeding of Chunkui cabbage. The overwintering of adult plants was suitable for large-area production and the overwintering greenhouses could be used for the original breeding and original breeding. The yield of spring kuwamu mother seed is mainly concentrated in the main branch and the first branch, the second branch has a certain yield, and the third branch in the production can obviously improve the yield and the quality.
