本试验用5个抗病材料与3个丰产感病品种共配制10个杂交组合。对各组合 F_1、F_2、F_3或 BC_1世代进行了抗性鉴定,结果表明:(1)AGS-9对 S_A 或 S_C 的抗性受单个显性基因控制,不受母本细胞质的影响;(2)广吉、AGS-9、大白麻中,抗 S_A 的基因具等位性,广吉、AGS-9、徐州424、兖黄1号中,抗 S_C 的基因亦具等位性,(3)广吉 AGS-9中,抗 S_A 的基因与抗 S_C 的基因相互连锁,其重组值为15.1±2.651%;(4)AGS-9中,抗 S_A 或 S_C 基因与控制下胚轴颜色、叶形及茸毛色等各基因呈独立贵遗传。
In this experiment, 10 hybrid combinations were prepared with 5 disease-resistant materials and 3 high yield susceptible varieties. The results showed that: (1) AGS-9 resistance to S_A or S_C was controlled by a single dominant gene, regardless of the parental cytoplasm; (2) The gene of anti-S_A in Guangji, AGS-9 and Dahema was allelic. The genes of anti-S_A in Guangji, AGS-9, Xuzhou 424 and Yanhuang 1 were also allelic, In AGG-9, the anti-S_A gene and the anti-S_C gene were linked to each other and the recombination value was 15.1 ± 2.651%. (4) The anti-S_A or S_C gene in AGS- And velvet color and other genes were independent of your genetic.
