辽宁省昭乌达盟农牧科学研究所从一九六九年开始探索谷子雄性不育系利用的问题。他们初步认为,通过物理、化学处理,远缘杂交或天然发现都可获得不育株,但都不同程度的表现出遗传的不稳定性,例如,用射线处理“185—3”品种在第二代出现了花药干瘪、不散粉的不育株率近三分之一,但在第三代,不育程度较高的系统大部分恢复了,而且第二代出现可育株,到第三代反而分离出不育株。针对这种情况,寻着谷子雄性不育株应从多方面入手。
Zhaowuda League of Agriculture and Animal Husbandry Science Research Institute of Liaoning Province from 1969 to explore the use of millet male sterile lines. They initially thought that sterile plants could be obtained by physical, chemical treatment, distant hybridization or natural discovery, but all showed genetic instability to some extent. For example, the treatment of “185-3” The second generation appeared anthers shriveled, sterile powder rate of nearly one-third of the plant, but in the third generation, most of the more sterile systems were restored, and the second generation of fertile plants, to the Three generations instead of sterile strains. In view of this situation, the search for millet male sterile plants should start from many aspects.
