采用8个我国当前流行的条锈菌生理小种(菌系)对三个易位系进行抗锈性评价,并用CYR30、CYR31、Su-4和单孢菌系CYR32-6对三个易位系与感病品种铭贤169配制的F1、BC1F1和F2代株系以及三个易位系之间双列杂交的F2株系进行遗传分析和等位性分析。结果表明:三个易位系是优秀的小麦抗条锈病资源;V9128-1对CYR30、CYR32-6和Su-4的抗病性由1对显性基因控制,对CYR31的抗病性由1显1隐2对基因独立控制,V9128-3对四个菌系的抗病性均由1对显性基因控制,V3对CYR32-6和Su-4的抗病性均由2对显性基因互补作用控制,对CYR31的抗病性由1显1隐2对基因独立控制或由1对显性基因控制;V9128-1与V9128-3对CYR31、CYR32-6和Su-4有相同或紧密连锁的抗病基因,且对CYR30、CYR32-6和Su-4的抗病基因与V3都不同,但与V3含有相同或紧密连锁的抗CYR31基因。
The rust resistance of three translocations was evaluated using 8 current races of Bacillus subtilis (bacterial strain), and the three translocations were tested using CYR30, CYR31, Su-4 and the monospora strain CYR32-6 The F1 and BC1F1 and F2 lines and the F2 lines between the two translocation lines were analyzed by genetic and allelic analysis. The results showed that the three translocation lines were excellent resistance to stripe rust of wheat. The resistance of V9128-1 to CYR30, CYR32-6 and Su-4 was controlled by one pair of dominant genes and the resistance to CYR31 was from 1 The results showed that the resistance of V9128-3 to four bacterial strains was controlled by one pair of dominant genes. The resistance of V3 to CYR32-6 and Su-4 was controlled by two pairs of dominant genes Complementarity control, disease resistance to CYR31 by 1 significant 1 hidden 2 gene independent control or by a pair of dominant genes; V9128-1 and V9128-3 of CYR31, CYR32-6 and Su-4 are the same or close Linked disease resistance genes, and the CYR30, CYR32-6 and Su-4 resistance genes and V3 are different, but with V3 contain the same or closely linked anti-CYR31 gene.
