在玉米制种工作中时常遇到这样的问题:有些配制组合,在花期相遇良好的情况下,母本结实率不高,出现“秃尖”、果穗基部“缺籽”现象,制约着制种产量。为此,我们进行了观察,探讨发生的原因、解决的办法。 据观察得知,有些配制组合的 In the seed production of maize, the following problems are often encountered: In some combinations, the seed setting rate is not high at the time of flowering, and the phenomenon of “bald tip” and “lack of seed” at the base of the ear restricts seed production Yield. To this end, we conducted observations, explored the causes and solutions. It is observed that some of the preparation of combination
