冬小麦新品种“山农辐63”是1974年秋用~(60)Coγ射线3万伦琴处理“蚰包×欧柔”F_4一个株系的干种子经过四代选育而成,比引变原始材料早熟5天;株高降低10cm;并提高了抗病性。该品种具有千粒重高(50g 左右)且稳定、适应产量的幅度大、丰产性好且成熟较早等优点。1978年—1980两年省区域试验的高肥组、中肥组及大区生产试验中,产量均名列第一,被列为山东省冬小麦推广品种。1983年秋播面积山东省为1673万亩,占冬小麦面积的28%,成为第一位的当家品种。同年外省种植126万亩,1980—1983年累计秋播面积合计为1798万亩,成为国内辐射育成的冬小麦品种中推广面积最大的一个。
The new winter wheat cultivar “Shannon-yong 63” was selected in the autumn of 1974 with ~ (60) Co γ-ray irradiation of 30,000 Roentgens to process the seeds of a line “Fongbao × Ouyou” F_4 after four generations. Change the original material premature five days; plant height reduced by 10cm; and improve disease resistance. The variety has a thousand-grain weight (50g or so) and stable, to adapt to large-scale production, high yield and good mature and so on. In the high-fat group, medium-fat group and large-scale production test in the provincial regional experiment of 1978-28080, the output of the two provinces ranked the first and was listed as the winter wheat promotion variety in Shandong Province. Autumn 1983 sown area of 16.7 million mu in Shandong Province, accounting for 28% of the area of winter wheat, becoming the first headed species. In the same year, other provinces planted 126 million mu of land, and the cumulative autumn planting area in 1980-1983 totaled 17.98 million mu and became the largest popularized area of the winter wheat cultivars bred in China.
