一九八五年一月十一日在广西南宁举行了第三次全国植物辐射遗传机理协作会。会议反映了我国这一领域研究的进展。一、辐射诱发染色体易位的研究和利用基本上建立了水稻易位体选育的程序,并选育了优质高产品种“塘二粘”及一批易位体。采用辐射处理远缘杂交种子,诱发小黑麦染色体易位率很高,已选育了若干6 RL/6 AL 易位系。有九个纯合易位系经过生产鉴定开始示范推广。二、辐射细胞方面提出了一个新的观点,即各种射线可能将得到最大突变率是相同的。
On January 11, 1985, the third national collaboration on plant genetic mechanism of plant radiation was held in Nanning, Guangxi. The meeting reflected the progress of research in this field in our country. First, the radiation-induced chromosomal translocation research and utilization basically established the process of rice translocation breeding and selection of high-quality and high-yielding varieties “Tang two sticky ” and a number of translocations. Treatment of distant hybrid seeds with radiation resulted in a high rate of chromosome translocation in triticale and several 6 RL / 6 AL translocations were bred. Nine homozygous translocations passed demonstration of production and started demonstration and promotion. Second, radiation cells put forward a new point of view, all kinds of rays may be the maximum mutation rate is the same.
