The author reviewed the main achievements of breeding work of cultived rice (O. sativa Subsp. hsien) in China in the past thirty years, which are as follows ?dwarf rice breeding; hybrid rice breeding and research and use of rice variety resources. The main experiences in rice breeding are : establishment of the breeding target from the demand of the production} the correct use of the rice variety resources) the improvement of the main characterss rapid reproduction of the generation, the mass movement in breeding work and coorperation in research practices) good seeds in combinaton with good methods. As for the prospect of the rice breeding, the author regarded that the target of breeding the high yeilding character, high resistance, good quality and early maturity should be put on the first place. The various kinds of breeding approaches based on hybridi zation must be combined together. To develop an integrated research on variety resources of rice and to stengthen the research on the application of the fundamental theories of rice breeding are important too.

作者总结三十年来我国籼稻育种的主要成就有:矮秆水稻育种;杂交水稻育种和水稻品种资源的研究利用。育种主要经验为:从生产需要出发确定育种目标;稻种资源的正确利用;主要性状的改良;加速世代育种的群众运动和协作攻关;良种和良法结合。对水稻育种的前景,作者认为育种目标仍应以高产为主,结合优质、抗性、早熟;以杂交育种为基础各种育种途径相结合;开展各学科对稻种资源的综合研究和加强有关水稻育种的应用基础理论研究。

From March, 1992 to Nov. 1993, we experimented on all types of malesterile rices with many chemical regulators in both Sanya,Hainan province and Changsha.Hunan province the results showed that male-fdertility -restoring regulators made the fertilities of photo-thermo-sensitive genic male-sterile rice (PTGMR)and cytoplasmic male-sterile rice(CMSR)restored to some extent in which the seed set rates were from 0. 1% to10. 0%,additionally, they could increase the seed set rates of PTGMR by 4. 4 % to 18. 4% under...

From March, 1992 to Nov. 1993, we experimented on all types of malesterile rices with many chemical regulators in both Sanya,Hainan province and Changsha.Hunan province the results showed that male-fdertility -restoring regulators made the fertilities of photo-thermo-sensitive genic male-sterile rice (PTGMR)and cytoplasmic male-sterile rice(CMSR)restored to some extent in which the seed set rates were from 0. 1% to10. 0%,additionally, they could increase the seed set rates of PTGMR by 4. 4 % to 18. 4% under fertile condition compared with control;and parthenogenesis-inducing regulators could cause all the sterile lines including ordinary genic male-sterile rice (OGMR),PTGMR,CMSR and streile plants of parthenogenetic F1 (PF1) to produce seeds, especially used with maleFertility -restoring regulators. We think it's necessary to continue deeply studying the mechanism and regulating technique of the restoration of fertility of male-sterile rice,and it's possible to lead to a new way for hybrid rice breeding.

1992年3月至1993年11月,我们先后在海南和长沙两地,使用多种化学调控剂处理了不同种类的不育系.结果表明:化学复雄剂对光温敏不育系及细胞质雄性不育系均有一定程度的恢复效应,结实率可恢复到0.1%~10.0%,且在繁殖季节能显著提高光温敏不育系的结实率,提高幅度达4.4%~18.4%.孤雌生殖诱导剂对所有供试的普通核不育系,细胞质雄性不育系、光温敏核不育系及孤雌生殖后代不育株均能诱导结实,且与化学复雄剂配合施用时,效果更好,继续深入研究不育系育性恢复的机理及调控技术,可望为杂交水稻育种开辟一条崭新的途径.

According to its background and characteristics,the hybrid rice male sterility genetics research in China has undergone three periods. The first period is from the middle of 1960s to the middle of 1970s, in which the hybrid rice research in China was being established.During this period the nuclear sterility and the nucleo-cytoplasm interaction male sterility genetics researches were mainly performed,and the male sterility theory with China’s characteristics was advanced.The second period is from the middle...

According to its background and characteristics,the hybrid rice male sterility genetics research in China has undergone three periods. The first period is from the middle of 1960s to the middle of 1970s, in which the hybrid rice research in China was being established.During this period the nuclear sterility and the nucleo-cytoplasm interaction male sterility genetics researches were mainly performed,and the male sterility theory with China’s characteristics was advanced.The second period is from the middle of 1970s to the middle of 1980s, in which the three-line hybrid rice research in China was carried rapidly forward.During this peri-od the genetics research was especially stimulated.The main characters of this period were that the further re-search Of the pleomorphism cytoplasmic male sterility materials was carried out and that a lot of important achievements in theories were crowned. The third period is from the middle of 1980s to present time, in which the three-line hybrid rice research expanded steadily and the two line hybrid rice research came to be launched. During this period the genetics research is also livening. There are two main characters of this peri-od, for one thing, the photoperiod(thermoperiod) sensitive genic male sterility genetics research is becoming the main goal, for the other, the molecular genetics research of the cytoplasmic male sterility and the photope-riod sensitive genic male sterility is making good progresses. The far-going significance and far-reaching ef-fect of the achievement in theories obtained in this period are unprecedented. But we all know that the main work of those achievements has been set up on the base that the phenotype deducts the genotype. As the fu-ture research direction of the hybrid rice breeding theory science, our research should be based on directly analysing the change of DNA alignment(realizing the transformation from Mendelian genetics to genome ge-netic, not on the phenotype deducting the genotype.

从宏观上根据我国杂交水稻的发展对我国水稻雄性不育性遗传学的研究划分为3个时期,并对每个时期的研究背景、特点和主要成果进行了综合述评。针对目前三系杂交水稻和两系杂交水稻的发展现状和面临的问题,作为指导杂交水稻育种的理论科学及其研究方向,应以表型推论基因型为基础转变为以直接分析DNA序列变化为基础,即实现从孟德尔遗传学到基因组遗传学的转变。
