Preliminary breeding report of w heat-resi stance to Scab using Tai gu male-sterile wheat

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.
