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。
Since 1992 ,7 pure wheat lines have been sent to space for 5 times by returned satelite. By more than 10 years of breading work, one new variety with high yield, disease resistance and high quality and 6 new lines have been bred. 2 lines have taken part in the regional test of the Heilongjiang province. New variety has been extended up to 40 000 hm^2. and very good social and economic benefit has been made. In accordance with character of space mutation, improvement method of breeding and enhancing efficiency of breeding have been studied.
