建国以来,由于长期忽视近代遗传学的教学和普及工作。十年浩劫,又使科技人员丧失了重新学习和研究的机会.致使我国农作物良种繁育的理论和技术,一直处于徘徊不前的局面。尤其是在怎样看待品种遗传和变异的问题上,一些片面的认识非但得不到及时纠正,反而长期居于支配地位,这就不能不影响良种繁育事业的发展。为此,本文就农作物品种群体的遗传和变异问题,介绍近代遗传学中有关的 Since the founding of the People’s Republic of China, due to neglect of the teaching and popularization of modern genetics for a long time. Ten years of catastrophe, but also to science and technology lost the opportunity to re-learn and research, resulting in China’s crop breeding theory and technology, has been in a lingering situation. In particular, on the question of how to treat the genetics and variation of breeds, some one-sided understandings have not only failed to correct them in time, but have been dominant for a long time, which can not but affect the development of breeding and breeding. To this end, this article on the genetic varieties and varieties of crop variability, introduced in modern genetics
