| 摘 要： | 为了明确抗源大秋其的衍生品系多抗１号对稻瘿蚊抗性的遗传背景，测定了多抗１号与感稻瘿蚊品种及不同抗稻瘿蚊基因抗源的杂交Ｆ、Ｆ２、Ｆ３和Ｔ１的抗性分析抗性分离比例，研究了多讥号对稻瘿蚊抗性遗传方式及其与一些有代表性抗源抗性基因的等位必关系。结果表明，多抗１号地广东稻瘿蚊的抗性由显性主基因控制。它的抗稻瘿蚊基因Ｃｍ－６、ａｌｅｕａｎｇ１５２、ＢＧ４０４－１、ＯＢ６７７的抗稻瘿蚊基因不等位，民羊山占的抗稻

| Abstract: | The resistance inheritance background of Duokang 1 to rice gall midge ( Orseolia oryzae (Wood-Mason))was explored, the resistance of filial generations F1 , F2, F3 and T1 of Duokang 1 and sensitive/resistant (possessing different resistant genes) varieties was tested, the proportions of resistance segregation were detemined, and the resistance inheritance mode of Duokang 1 as well as the allelisms among Duokang 1 and other representative resistant sources were analyzed. The results showed that the resistance of Duokang 1 to Orseolia oryzae is controlled by a single dominant gene Gm-6, which is nonallelic to those of Leuang 152, BG404-1 and OB677, but linked with that of Yangshanzhan, and different from gm-3 in ARC 5984. The application perspective of Gm-6 was discussed. |
