The Progress on the Breeding of Resistance to Verticillium Wilt in Cotton
This paper concluded the achievements and progress of anti-verticillium breeding in recent 10 years, and indicated that the most effective and feasible method to control verticillium wilt was planting disease-resistant varieties of cotton currently. This paper also analyzed the problems in anti-verticillium breeding, and obtained five main problems as follows:(1) Lack of upland cotton anti-source of high resistance;(2)The cycle of anti-verticillium breeding was long and the breeding method was single;(3) The discipline of genetic resistance was not clear and the basis of genetic resistence was narrow;(4) Molecular marker assisted selection existed a lot of limitations in anti-verticillium breeding; (5) The identification methods of anti-verticillium was defected. This paper discussed the way to deal with the problems as follows:(1) Through the distant hybridization, and combined with many generations of backcross and directional selection to create new species;(2) Using physical chemical and molecular mutagenesis or other means to create new materials;(3) Through the modern biological technology, cultivate new resistance materials; (4) Only importing the resistance gene or using RNAi technology to cultivate resistance plants. At the same time the paper prospected the direction of the future research in anti-verticillium breeding. Researchers had been fostered many new disease-resistance varieties by various breeding ways, but there was lack of varieties which are true and high disease-resistant in cotton production.
