玉米大面积制种时人工去雄,需花费大量劳动力,而且还很难保证制种质量。据调查,单交种生产田里的自交苗,一般占10%的比例,影响增产潜力的发挥。不育化制种,正是解决这个问题的好办法。但由于种种原因,国内不育化制种,迄今未普遍实现。在加快实现农业现代化的今天,玉米不育化制种,应当是刻不容缓的重要任务。 Large areas of maize seed artificial breeding, need to spend a lot of labor, but also difficult to ensure the quality of seed production. According to the survey, a single cross-breeding self-production seedlings in the field, the proportion of 10% of the general, affecting the yield potential to play. Sterile seed production, it is a good way to solve this problem. However, due to various reasons, the domestic sterile seed production, so far not universally realized. In accelerating the realization of agricultural modernization today, maize inoculation should be an urgent and important task.
