摘　　要：为了增加青花菜台绿5号的制种产量,研究了不同父母本行比(父本:母本=1:1、父本:母本=2:1)和母本播期(8月10日、8月20日)对制种产量及相关性状的影响。结果表明:制种时父母本2:1处理的单株有效荚数为735.13荚、每荚粒数为2.04粒、折合667 m2产量为6.42 kg,分别极显著高于父母本1:1处理的362.42荚、1.31粒、2.35 kg;2个母本播期处理对制种产量及相关性状的影响不显著,但从父母本花期的相遇时间来看,母本播期选择8月10日更合适。因此,建议在台绿5号制种时选择父母本行比为2:1,母本播期以8月10日为宜。In order to increase the seed yield of ’Tailü No. 5’ of broccoli, the effects of different parent row ratio(male:female=1:1, male:female=2:1) and sowing dates of female parent(August 10th, August 20th)on seed yield and related traits of ’Tailü No.5’ were studied. The results showed that in the seed production of ’Tailü No.5’, the seed yield of 2:1 treatment(735.13 effective pods per plant, 2.04 seeds per pod, 6.42 kg per 667 m2) was extremely and significantly higher than that of 1:1 treatment(362.42 effective pods per plant, 1.31seeds per pod, 2.35 kg per 667 m2). The effects of two sowing dates of female parent on seed yield and related traits were not significant, but from the perspective of the meeting time of parent flowering, August 10th was more suitable for the sowing date of female parent. Therefore, it was suggested that the ratio of parent(male:female) should be 2:1, and the sowing date of female parent should be August 10th for seed production of ’Tailü No.5’.
