Development and Use of Multiple-pest Resistance to Improve Production Efficiency of Peanut


The goal of UFL 16P was to compare U.S. peanut breeding lines with Bolivian lines for disease and insect resistance. Bolivian germplasm will be evaluated in the U.S. environment and U.S. germplasm in the Bolivian environment, with benefits to both countries.


Initial studies have produced valuable data on cultivars for solving the constraints in the host country, and rust and leaf spot are diseases of major interest. Measures of yield loss are now available, and the benefits of introduced germplasm are now becoming apparent. Farmer field days have been held, extension publications, and grower manuals for farmers were planned. Seed multiplication activities were planned and implemented, and collaboration with ANAPO (AsociaciĆ³n de Productores de Oleaginosas y Trigo), a non-government producer organization has particularly good potential for technology transfer (deployment of superior quality seed and, in time, new cultivars). The development of Tomato Spotted Wilt Virus (TSWV)-resistant genotypes will have very strong applicability for the H.C., as well as in the U.S. and other countries.
