【Abstract】 The proceedings on breeding for resistance to Fusarium Oxyzporum and Verticillium dahliae, resistance identification of germplasm resource in cotton are reviewed in this paper. Three kinds of method for antidisease identification and operational regulation are also introduced systematically. Differentiation of pathogenic bacterium physiological type from Fusarium Oxyzporum and Verticillium dahliae, and analysis for intimate relationships between different Verticillium dahliae strains by DNA fingerprinting, are summarized. At the same time, the inheritance types of resistance to Fusarium Oxyzporum and Verticillium dahliae, and molecular marker assisted selection for resistance to Verticillium dahliae in cotton are expounded. The reasons of tardy progress on breeding for resistance to Verticillium dahliae, and developmental countermeasures are set forth. According to the situation of seedling and boll disease occurring increasingly, further development on breeding for resistance to disease in cotton are discussed.更多还原
