解放以来,经过各地农业科学工作者积极努力,深入农村,从事小麦地方品种和推广品种的调查和整理,取得了不少成绩,不但明确了若干因地制宜的良种,并为进一步提高现有的品种,提供了宝贵的材料。随着互助合作运动和水利建设的蓬勃发展,各地原有的小麦品种,日益不能满足生产上的要求,而小麦新品种培育工作又属于农业基本建设性的工作之一,非短期内所能奏效,目前各省农业科学研究所或综合试验站在小麦品种整理的基础上,正在计划先后开展新品种培育工作,因此提出有关小麦有性杂交选种的几个 Since liberation, agricultural scientists from all over the country have made a lot of efforts in their efforts to go deep into the countryside and investigate and sort out varieties of wheat and popularized varieties. Not only has it clarified a number of improved varieties that are suited to local conditions, but also made further efforts to further enhance existing varieties, Provided valuable material. With the vigorous development of mutual aid and cooperation and water conservancy construction, the existing varieties of wheat in various places are unable to meet the production requirements increasingly. However, the cultivation of new varieties of wheat belongs to the basic agricultural construction and can not be implemented in a short period of time At present, the provincial agricultural science research institutes or comprehensive experimental stations are planning to carry out the cultivation of new varieties on the basis of finishing wheat varieties. Therefore, several studies on selective hybridization of wheat are proposed
