| 摘 要： | 用稻瘟病(Pyricularia oryzae)的菌株75-49和0206-1(分别代表ZB和ZC群小种)接种抗病品种窄叶青8号、珍龙13与感病品种朝六早、朝阳一号的杂交组合,根据F1、F2、F3和B1F1分析结果,窄叶青8号对菌株75-49和0206-1的抗性由两对抗性基因控制,而珍龙13对菌株0206-1的抗性由单显性抗性基因控制。

| Abstract: | F1.F2.F3 and B1 F1 plants of crosses of resistant parents Zhen-long No.13 and Zhai-Ye-qing No.8 with susceptible parents Zhao-lu-zao and Zhai-yiang No.1 were inoculated with two strains,75-49(ZB1) and 0206-1(ZC13) of Pyricularia oryzae.The results suggest that the resistance of Zhen-long No.13 to fungus strain 0206-1 is controlled by a single dominant gene,Py-1;the resistance of Zhai-ye-qing No.8 to two fungus strains,75-49 and 0206-1,is controlled by two genes,Py-2 and Py-3. |
