一九七五年以来,我们先后收集了500多份国内外水稻良种,对其再生能力进行试验.从这方面的试验研究看,水稻的再生能力,一般与品种、环境、再生能力遗传都有着密切的相关.现将试验结果综合如下:一、再生能力与品种关系:从国内外500多份材料的再生能力测定看,其品种间的再生能力的差异是很大的.其中只有50～60%品种有再生能力,而40～50%品种再生能力都较弱.在有再生能力品种中,矮
Since 1975, we have collected more than 500 varieties of rice at home and abroad to test their ability to regenerate.From this point of view, the regenerative ability of rice, in general and with varieties, environment, and genetic regeneration have Closely related to the test results are summarized as follows: First, the relationship between reproductive capacity and variety: From the domestic and international analysis of the reproducibility of more than 500 materials, the ability to reproduce the difference between varieties is very large, of which only 50 ~ 60 % Of varieties have regeneration ability, and 40 ~ 50% of varieties have weaker regeneration ability. Among varieties with regenerative ability, short
