汤泽生教授对棉花雄性不育小孢子败育的细胞学研究从1972年开始历经十八年,其成果于1990年8月经四川省教委组织省内外专家进行了鉴定验收。专家们一致认为:该项成果对棉花洞A不育系、阆A不育系、洞A_3不育系、新海不育系、海洞不育系等棉花雄性不育系从小孢子母细胞、减数分裂、以及小孢子的发育过程等的研究,论证了棉花雄性不育系的败育时期及其变化。发现了不同基因控制的棉花雄性不育系的小孢子败育除具有某些共同点外,还各有自己的特点。从而可以根据不同棉花雄性不育系小孢子败育的特点来辅助鉴定不同棉花雄性不育系的基因型。该项研究对棉花雄性不育的机制,从细胞学方面进行了比较系统、全面的研究。立题新颖、目标明确,为棉花雄性不育提供了理论上的依据,为棉花杂种优势利用开辟了 Professor Yu Zesheng on cotton male sterile microspore abortion cytology from 1972 onwards after eighteen years, the results in August 1990 by the Sichuan Provincial Board of Education organized experts inside and outside the province were identified acceptance. The experts agreed that the results of cotton CMS sterile line A, 阆 A CMS, Cave A_3 CMS, Xinhai CMS, CMS and other sterile CMS lines from microspore mother cells, minus Number division, microspore development process and so on, demonstrated the male sterility of cotton abortion period and its changes. It was found that in addition to some commonalities, microspore abortion of cotton male sterile lines with different gene control also had their own characteristics. Thus, the genotypes of different cotton male sterile lines can be identified according to the characteristics of microspore abortion in different male sterile lines of cotton. The research on cotton male sterility mechanism, a more systematic and comprehensive study from the cytology. The novel, the goal is clear, provides a theoretical basis for cotton male sterility, opened up the use of cotton heterosis
