省农科院粮作所西峰试验组(1955-57年由西科所陇东工作组)与庆阳地区农科所(前身为平凉地区农试站)小麦组合作,自1955-1968年开展陇东地区冬小麦新品种选育工作,经过长期共同努力,育成西峰1号至14号、庆选1号至30号(原为区试号)、以及后来该所育成的庆丰1号,共45个品种(系)。这批品种(系)先后在生产上推广应用,对提高陇东旱地冬小麦产量,收到了显著的效果。据1981年秋播后的不完全统计,庆阳地区种植面积已达到150多万亩,占该区冬小麦播种面积将近一半;平凉地区也有相当面积。回顾育种实践,在育种目标确定之后,正确选配组合是旱地冬小麦杂交育种工作成败的关键。 The provincial Academy of Agricultural Sciences grain work Xifeng experimental group (1955-57 by the West Branch Longdong Working Group) and Qingyang Agricultural Research Institute (formerly Pingliang area agricultural test station) wheat group, since 1955-1968 Longdong new varieties of winter wheat breeding work, after long-term joint efforts, bred Xifeng No. 1 to No. 14, celebrate No. 1 to No. 30 (formerly District No.), and later bred Qingfeng No. 1, a total of 45 varieties (lines). These varieties (lines) have in the production of popularization and application, to improve the winter wheat yield in Longdong dry land, received a significant effect. According to incomplete statistics after the autumn broadcast in 1981, the planting area in Qingyang reached more than 1.5 million mu, accounting for nearly half of the winter wheat sown area in the area; there was also a considerable area in Pingliang. Reviewing the practice of breeding, the key to the success or failure of crossbreeding of winter wheat in dryland is to choose the right combination after the goal of breeding is established.
