摘要
东北春麦区为我国春种小麦主产区。建国前虽推广 13个抗旱丰产类型品种 ,但均不抗秆锈病 ,致使秆锈病严重 ,威胁小麦生产。建国后 5 0年来各级政府十分重视小麦品种改良工作 ,明确了以抗病为中心的高产、优质、适应性强适于集约化栽培为育种目标 ,控制了秆锈病的为害 ,使单产稳步提高。期间先后共育成审定 2 10个优良品种 ,大面积更换品种 4～ 5次 ,每次更换品种对促进小麦生产发展起到了重要作用。在遗传育种基础理论上做了大量研究工作 。
The Northeast spring wheat area is the main part of wheat sown in spring. Before 1949, 13 wheat varieties were released but they are susceptble to stem rust, so wheat production here strained by the disease. In the fifty years since 1949, wheat improvement was paid more attention by government, and clarified high yield, high quality, adaptive and suit for intensive cultivation as well as disease resistance as breeding objective. After that, stem rust was controlled effectively and yield was increased. During past 50 years, 210 wheat varieties were released, and cultivars were alternated 4～5 times. The alternation of cultivars played important role in promoting wheat production We also did large amount of work in basic theory study on genetic breeding and got much progress.
