不同播期对萝卜杂交种种子质量和产量的影响

摘要

为了在云南开发萝卜杂交种子生产基地，以雄不育系和自交不亲和系为萝卜亲本的试材，进行不同播期的生产试验，研究萝卜各处理间的生长期、种子产量和质量等方面的差异。结果表明：播期与生长量呈正比，不同播期对开花期没有明显的影响，但对萝卜种子的产量和质量有显著影响，10月15日播种生产出的萝卜种子的产量和质量最好。%In order to develop production base of radish hybrid seed in Yunnan ,taking radish sterility and self-incompatible lines as materials ,the differences of radish growing period ,seed yield and quality between different treatments were studied .The results showed that sowing date were proportional to the growth .Different so-wing dates had no significant effect on flowering stage .Sowing dates affected radish seed yield and quality ,the yield and quality on October 15 were the best .
