- 摘要:
- 从1992 年以来, 利用返回式卫星先后5 次共搭载7 份小麦纯系材料种子, 经10 多年工作选育推广了高产抗病品质优良的新品种1 个, 进入省区试的品系2 个, 参加产量鉴定的品系4 个。截至2005 年新品种累积种植面积达4 万hm2 , 获得了较好的经济和社会效益。同时针对航天诱变的特点, 进行了改进育种方法和提高诱变效果的研究。
- Abstract:
- Since 1992 , 7 pure w heat lines have been sent to space for 5 times by returned satelite .By mo re than 10 years of breading w o rk , one new v ariety w ith high yield , di sease resistance andhig h quali ty and 6 new lines have been bred .2 lines have taken part in the regional test of theHeilo ng jiang province .New v ariety has been extended up to 40 000 hm2 , and ve ry goo d social and economic benefit has been made .In acco rdance w ith character of space mutation , impro vement method o f breeding and enhancing eff iciency of breeding have been studied .
