Report on Hybrid Seed Production of Brassica chinensis

采用种子温室育苗和直播两种方法,研究对上海青油白菜杂交制种产量的影响,结果表明种子育苗制种折合产量88.9㎏/667m2,比种子直播制种增产50.9%。建议有育苗条件的地区采用这种方法进行制种。

Greenhouse seedling and direct seeding are adopted for studying the effects of the two methods on the hybrid seed production of Brassica chinensis. The results show that the breeding by seedling goes to a yield of 88.9kg/hm^2 ,50. 9 % more than the yield of breeding by direct seeding. It is suggested that in areas, where seedling condition permits, this method be used for breeding.
