人们在生产斗争和科学实验中,往往根据生物体桔构与功能的辩证关系,促使生物内部结构的变异,反作用于功能,从而有效地控制改造生物。例如,利用理化因素处理农作物的种子或植株,诱发农作物内部结构发生突变,选育新的品种,已成为当前作物育种工作中一条重要的途径。 在毛主席的革命路线指引下,贯彻教学、科研和生产三结合的方针,从一九七○年起,我们组成“三结合”队伍,开展了水稻诱变育种的研究。经过四年多来的实践,初步选育出几个较好的水稻新品种和一批优良的新品系;同时,还探讨了水稻诱变育种工作中几个有关问题。现主要就后面一个问题摘报于后。 In the struggle for production and in scientific experiments, people often promote the transformation of biological internal structure to function in response to the dialectical relationship between the structure and function of the organism, thus effectively controlling the transformation of living organisms. For example, the use of physico-chemical factors in the treatment of crop seeds or plants to induce mutations in the internal structure of crops and to breed new varieties has become an important approach in current crop breeding. Guided by Chairman Mao’s revolutionary line, we have followed the principle of teaching, scientific research and production. Since 1970, we have formed a team of “three combinations” and conducted research on mutation breeding in rice. After more than four years of practice, several good new varieties of rice and a number of excellent new lines have been initially bred; at the same time, several related problems in the breeding of rice by mutation have also been discussed. Now mainly on the back of a problem reported later.
