Reaction of common bean varieties ( Phaseolus vulgaris L.) to the infection for Uromyces phaseoli (Pers.) Wint var. typica Arth

Abstract

It was evaluated the reaction of twenty-five common bean varieties to Uromyces phaseoli (Pers.)Wintvar. typica Arth infection using the methodology informed by the Colombian International Center of Tropical Agriculture (CIAT). These experiments were developed in the Agricultural Experimental Station belonging to the Agricultural Sciences Faculty of Las Villas Central University, under a design of random blocks with four repetitions in the period between January to April 2011. The evaluations of infection intensity and pustule type were carried out weekly starting from the beginning of disease symptoms in 15 plants for varieties. Results evidenced differences in the response of varieties as well as a different behavior to the infection for this phytopathogen fungus. Guama 23 variety was classified as resistant highly to the infection for U. phaseoli. This work constitutes a fundamental tool for future programs on genetic improvement of common bean cultivation in Cuba.
