Genetic variability within Phaeoisariopsis griseola from Central America and its implications for resistance breeding of common bean

Autor: Mahuku, George S. Jara, Carlos E. Cuasquer, Juan B. Castellanos, G.

The genetic and virulence variability of 112 isolates of Phaeoisariopsis griseola, collected from various locations in Central America, were studied using seven random amplified polymorphic DNA (RAPD) primers and 12 common-bean differential genotypes. Broad molecular diversity (H = 0·92) among is...

Pathogenic variation in, sources of, and breeding for resistance to Phaeoisariopsis griseola causing angular leaf spot in common bean

Autor: Pastor Corrales, Marcial A. Jara, Carlos E. Singh, Shree P.

If we are to breed common bean (Phaseolus vulgaris L.) for durable resistance to diseases, we must understand pathogenic variation and find sources of resistance. Our first objective was to determine the patterns of pathogenic variation found among isolates of Phaeoisariopsis griseola (PG), the f...

Metodo para obtener alta severidad de la roya del frijol en areas con humedad relativa baja

Autor: Castaño Zapata, Jairo Jara, Carlos E.

A total of 18 bean var. with different degrees of rust resistance in the field were subjected to 4 treatments, to obtain high severity of Uromyces phaseoli under low RH. Treatments were (1) greenhouse inoculation, with optimum temp. and RH for disease development, (2) field inoculation in infecti...
