摘要
用生物间遗传学的方法,在温室苗期根据59个冬小麦品种与6个条锈菌优势小种相互作用所表现的侵染型,推导出了分别在Compair、Heines Ⅶ、14Th43、Lee、CA8333、Vilmorin23、丰抗2号、冬协4号、ABNA、9D27-262、S-13、S-14以及绝大部分高代品系和目前正在推广的品种中可能含有的12个抗条锈性基因(1h1～1h12).用生物间遗传学原理进行遗传学研究,可以不通过杂交在短期内对大量抗病品种的遗传信息进行了解,这为抗病育种和品种合理布局提供依据.本文讨论了应用生物间遗传学分析抗性基因的局限性.
Fifty-nine winter wheat varieties were inoculated respectively with six yellow rust cultures at seedling stage in green house. Genotypes of winter wheat varieties and pathogen were analysed based on infection types expressed by the method of interorganismal genetics. Twelve resistance genes (1h1-1h12) were determined. The results were fundamentally coincident with what observed in field and therefore were useful for disease resistance breeding program and deployment of varieties released. The limitations of application of interorganismal genetics were discussed in this paper.
