Minority Affairs Symposium - Plants and Human Nutrition Winston, Eugenia [1]. Genetic and cultural methods to control reniform nematode in cotton. The reniform nematode, Rotylenchulus reniformis, has emerged as a major problem in cotton production in the southeastern United States during the past 10 years. In Mississippi alone, the nematode was estimated to decrease cotton lint yield by approximately 10% in 2000. This project was initiated to incorporate resistance into upland cotton from related diploid species as well as existing level of resistance in Gossypium hirstum through conventional breeding methods. Improved techniques to separate resistant and susceptible progenies to allow for an efficient and extensive breeding effort will be developed. Because the development of resistant cultivars takes several years, the efficacy of existing cultural practices will be confirmed for the Mid South region, and these cultural practices will be developed into a management system. Expected outcomes include resistant germplasm developed both from related species and from G. hirsutum, improved evaluation techniques to identify resistance progenies, and a system to manage losses to the nematode using production practices.
