- 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50 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210 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, 取得了丰硕研究成果。
- Abstract:
- The Northeast spring w heat area is the main part of w heat sown in spring .Before 1949 , 13w heat v arieties were released but they are susceptble to stem rust , so wheat production here st rainedby the disease .In the fif ty years since 1949 , w heat improvement w as paid mo re attention by government, and clarified high yield , high quali ty , adapt ive and suit fo r intensive cultiv ation as w ell as diseaseresistance as breeding objective .After that , stem rust was controlled ef fectively and yield w as increased.During past 50 years , 210 w heat varieties w ere released , and cultivars w ere alternated 4 ~ 5times .The alternatio n of cultivars played important role in promoting wheat production.We also didlarge amount of w ork in basic theory study on genetic breeding and go t much progress .
