In: In: Michigan State University. Agricultural Experiment Station. Saginaw Valley bean-beet research farm and related bean- beet research: 1980 Research ReportSummary: Se describen y analizan brevemente los diferentes cruzamientos realizados con frijol blanco, negro y arrinonado para buscar resistencia a las razas alfa, beta, delta y gamma de Colletotrichum lindemuthianum. Estudios recientes con San Fernando (semilla negra) y NEP-2 (semilla blanca) han indicado que estos cv. tienen resistencia a las razas beta, gamma y delta, pero son susceptibles a la raza alfa. La mayoria de los arquetipos actuales que poseen ascendencia de San Fernando o NEP-2 muestran el mismo tipo de reaccion. Una vez se obtienen lineas mejoradas con reacciones deseables a las razas alfa, beta, gamma y delta, se puede identificar la fuente genetica de su resistencia. (CIAT)Summary: The different crosses carried out with navy, black, and kidney beans to search for resistance to the alpha, beta, delta, and gamma races of Colletotrichum lindemuthianum are briefly described and analyzed. Recent testing of San Fernando (black seed) and NEP-2 (white seed) has indicated that these cv. are resistant to beta, gamma, and delta races, but susceptible to the alpha race. Most of the current architypes having San Fernando or NEP-2 in their parentage show the same type of reaction. Once breeding lines with desirable reactions to the alpha, beta, gamma, and delta races are obtained, the genetic source of their resistance could be identified. (CIAT)
