项目摘要

Populations of artificial autotetraploids of rice (Oryza sativa L. cvs. Nipponbare and Fukunishiki) were repeatedly irradiated with gamma-rays through several generations. Plants which did not differ in appearance from the original diploid plants occured occasionally in the populations. These plants were designated as diploid-like plants. Nine diploid-like plants were obtained so far, and their generations were advanced without irradiation in order to examine the mode of segregation of characters in their progeny. The results indicated that the diploid-like plants with multiple mutant characters could be obtained and that dominant characters, i.e. awned spikelet and colored apiculus, were included in the mutant characters. The observation of chromosomes revealed that the diploid-like plants had the same number of chromosomes (2n = 24) as diploid rice plants had. We failed in detecting microscopically the structural changes of chromosomes. We have been exploring the application of restriction fragment length polymorphism (RFLP) analysis to the problem.
人工同源四倍体水稻(Oryza sativa L.)栽培变种Nipponbare和Yunnishiki)在几代人中反复接受伽马射线照射。在种群中偶尔出现与原始二倍体植株外观无差异的植株。这些植物被指定为二倍体样植物。到目前为止,获得了9个二倍体样植株,并在没有辐照的情况下将其世代推进,以检查其后代中性状的分离模式。结果表明,获得了具有多个突变性状的类二倍体植株,其中颖花有芒和顶尖有色是显性性状。染色体观察结果表明,拟二倍体植株与二倍体水稻植株的染色体数目相同(2n = 24)。我们未能在显微镜下发现染色体的结构变化。我们一直在探索应用限制性片段长度多态性(RFLP)分析的问题。
