玉米杂种优势的利用使玉米产量有了很大的提高，但由于玉米是异花授粉作物，在配制杂交种时需要人工去雄，不仅增加了劳动强度，提高了种子生产成本，而且会因去雄不彻底难以保证杂交种的质量。利用雄性不育系配制玉米杂交种是提高玉米杂交种子质量的关键措施之一。泰安市农科
The utilization of maize heterosis has greatly increased the yield of maize. However, since maize is cross-pollination crop, artificial de-homing is needed in the preparation of hybrids, which not only increases the labor intensity but also increases the cost of seed production, Male does not completely guarantee the quality of hybrids. It is one of the key measures to improve the quality of corn hybrid seed by using male sterile lines to make corn hybrids. Tai’an City Department of Agriculture
