甘肃省小麦品种演替过程及其发展方向

据不完全统计，建国50多年来，甘肃省通过审定（认定）和生产上曾有较大种植面积的小麦品种达369个，其中冬小麦177个、春小麦192个，这些品种大致经历了6次更新换代，单产水平在1949年的基础上翻了约4倍，总产增加了5倍多，蛋白质含量由“六五”的12.9%上升到“九五”的15.1%，赖氨酸含量由0.36%上升到0.48%。目前小麦生产存在的主要问题是：播种面积大幅下滑，单产水平处于新的爬坡阶段，加工品质普遍偏低，供需矛盾加剧。因此，今后小麦育种工作应在加大种质资源信息交流的基础上，朝着选育优质专用、超高产、抗旱节水型等新品种的方向发展，提升小麦综合生产能力。

The Process and Direction of Wheat Variety Revolution in GanSu

According to incompletely statistic, Since The People's Republic of China founded 50 more years, there are 369 wheat varieties that have passed authorized and have biggish planted areas have been achieved in Gansu province.Among them, 177 varieties are winter wheat,192 spring wheat.These varieties approximately undergo 6 renovations. The yield has increased about 4 times based on that of 1949's, and total yield about more than 5 times,The protein proportion has increased from 12.9% in the sixth five-year-plan to 15.1% in the ninth five-year-plan,and lysine from 0.36% to 0.48% during the same time. These wheat varieties have made great contribution for agriculture production of Gansu province.And now,the main problem in wheat production in this region is plant areas being declined, the unit area's production is hard to improve and machining quality is low, supply and requirement conflict is pricking up. So the breeder are facing the task to improve wheat yield, high quality, resistance drought and water-saved based on the intercommunion of germplasm.
