摘要: 选择抗赤性较好的太谷核不育小麦复合杂交第一代组合,组成混合选择群体,利用一批抗赤性较好的品种作为父本,通过两者间的自由杂交,使抗赤基因累加和重组,然后通过系谱选择法,进行抗赤霉病小麦新品系的选育。经1989年江苏省农科院植保所针注接种鉴定,结果表明:30个品系中有27个赤霉病抗性达到抗级。此外,还有16个品系同时在江苏农科院植保所针注接种鉴定,结果表明有9个品系赤霉病抗性达到抗级.本文还对选育经验进行了讨论。Abstract: Using F1 of Taigu male-sterile wheat with resistance to Scab as the female parent and the varieties with better resistance to Scab as the male parent, crosses were maded, breeding wheat resistance to Scab were carried out by recurrent selection. The results of field-resistance-appraisal showed that in Nan-ping Institute of Agricultural Science in 1989. the resistance of 27 lines among 30 varieties performanced better than that of Su-M ai No.3. Sixteen lines were identified for disease resistance by injecting inoculation method in Jiangsu Institute of Plant Protection. The results showed the resistance to Scab of 9 lines reached the resistance level. The paper briefly summarize the experimences of the select-breeding.
