棉花黄萎病菌致病力分化与寄主抗病性遗传研究进展

Review on the Differentiation of V.albo-atrum and V.dahliae and the Resistance Inheritance in Cotton

棉花黄萎病是世界各主要产棉国家和地区普遍发生和危害最重的病害之一，本文综述了棉花黄萎病菌致病力分化与寄主抗病性遗传研究进展。病菌种内存在着明显的致病力分化。寄主抗病性的遗传在种间和种内材料间亦存有差异。为了定向而有效地培育抗病品种、合理进行品种布局，对此类问题仍需进一步研究和探讨。

Verticillium wilt is one of the most severe diseases of cotton and is known to oc-cur in most cotton growing areas of the world.The progresses was reviewed of the re-search of the differentiation of V. albo-atrum and V. dahliae and cotton resistance inheri-tance.It was generally accepted that the pathogenicity differentiation existed among thestrains of the Verticilium species. The type of inheritance of cotton resistance to the fun- gus was different among the materials used for evaluation,especially in Gossypium hirsu- tum. In order to efficiently develop the varieties resistant to various straing of forms of thefungus,such problems need further study,
