摘要
通过春小麦与中间偃麦草二体异附加系 Z4 (2 n=4 4 )杂交、回交 ,将条锈病多小种抗病基因导入到春小麦中 ,获得了 4个在成株期高抗条锈病的春小麦新种质 ,其中优良穗系 0 P1343- 1苗期对流行小种条 30、条 32、水源11- 13完全免疫 ,对条 2 9、条 31免疫 ;0 P1341- 2 - 2对流行小种水源 11- 13免疫 ,对条 32高抗 ,对条 2 9、条 30、条 31中感。
Through the transference of gene resistant to stripe rust into spring wheat by hybridization between Thinopyrum intermedium disomic addition line and spring wheat, back crossing, four new strains of spring wheat with high resistance at the adult stage had been got. The strain 0P1343 1 was complete immunity for race 30, 32, Shuiyuan 11 13 at the seedling stage. The another starin 0P1341 2 2 was immunity to Shuiyuan 11 13, and showed high resistance to race 32 and medium susceptible to race 29, 30 and 31.
