1980年开始以农垦58s、双8-14s 为材料,进行光敏感核不育水稻的遗传、光周期诱导、生理生化及利用研究。农垦58s 与农垦58品种杂交,光敏核不育性表现为一对主效基因控制的遗传行为,农垦58s 与不同生态型的早、中、晚粳品种杂交,表现为复杂遗传行为,光敏性与感光性呈独立遗传,但感光性对光敏不育性表达起重要调节作用。阐明了农垦58s育性转换的敏感期、光长、光质、光间断作用和红光远红光效应。开展了激素、多胺、总RNA 和酶系统研究,提出了光敏核不育性的调控模型。成功转育多种类型籼、粳光敏感核不育系,两系杂交稻开始在生产上利用。
Starting from 1980, Nongken 58s and Shuang 8-14s were used as materials to study the inheritance, photoperiod induction, physiological and biochemical characteristics and utilization of photosensitive genic male sterile rice. Nongken 58s was crossed with Nongken 58, and photoperiod sensitivity was controlled by a pair of major genes. Nongken 58s crossed with early, middle and late japonica varieties with different ecotypes, showing complex genetic behavior, Sensitivity was independently inherited, but photosensitivity played an important regulatory role in photositive sterility. The sensitive period, light length, light quality, photointerruptive effect and red far red effect of Nongken 58s fertility transformation were elucidated. The research on hormone, polyamine, total RNA and enzyme system was carried out, and the regulation model of photo-sensitive nuclear sterility was put forward. Successfully transferred many types of indica and japonica-sensitive genic male sterile lines, two-line hybrid rice began to be used in production.
