Pseudocercospora Griseola

Common bean (Phaseolus vulgaris L.) is the most important edible legume in the world and is an important source of income for farmers and food for millions of families. Angular Leaf Spot (ALS), caused by the fungus Pseudocercospora griseola (Sacc.) Ferraris, is one of the most important diseases in the production of common bean with the potential to cause significant seed yield losses. An effective and environmentally friendly alternative to control this disease is the use of improved varieties that combine resistance genes of Andean and Mesoamerican origin. In this study, the response of 181 bean genotypes (coming from different breeding programs of several countries including the USA, Puerto Rico, Honduras, Ecuador, Colombia, Tanzania, Malawi, and Angola) to two angular spot isolates (races 61:11 and 63:51, prevalent in Isabela and Juana Díaz, Puerto Rico) were evaluated. Many of these genotypes contained resistant genes to different biotic and to abiotic stress. A total of 16 lines were identified to have resistance to both races. The resistant lines include the Andean breeding lines CAL 143, 277 and the Mesoamerican cultivar ‘Ouro Negro’ that possess the resistance genes Phg-5, Phg-1, Phg-3, respectively. This information can help common bean breeding programs to pyramid genes from the Andean and Mesoamerican gene pools to generate varieties with long-lasting resistance to this disease.

Due to the increased importance of angular leaf spot of common bean (Phaseolus vulgaris) in Brazil, monitoring the pathogenic variability of its causal agent (Phaeoisariopsis griseola) is the best strategy for a breeding program aimed at developing resistant genotypes. Fifty one isolates of P. griseola collected in five Brazilian States were tested on a set of 12 international differential cultivars in the greenhouse. When inoculated plants showed symptoms but no sporulation was observed, they were transferred to a moist chamber for approximately 20-24 h. After this period of time, if no sporulation was observed, the plants were considered resistant; otherwise, they were considered susceptible. From the fifty-one tested isolates, seven different pathotypes were identified. No Andean pathotypes were identified; consequently, all isolates were classified as Middle American pathotypes. Pathotype 63-31 was the most widespread. Pathotype 63-63 overcame resistance genes present in all differential cultivars and also the resistance gene(s) present in the cultivar AND 277. This fact has important implications for breeding angular leaf spot resistance in beans, and suggests that searching for new resistance genes to angular leaf spot must be pursued.

I Gene

Two 24-mer SCAR primers (SW13) were developed from a previously identified 10-mer RAPD primer (OW13690) linked to the I gene, which conditions resistance to bean common mosaic virus (BCMV) in common bean. Linkage between SW13 and the I gene was tested in three F2 populations segregating for both SW13 and the I gene: N84004/Michelite (1.0 ± 0.7 cM), Seafarer/UI-114 (1.3 ± 0.8 cM), and G91201/Alpine (5.0 ± 2.2 cM). SW13 proved to be more specific and reproducible than the OW13690 RAPD marker. Using different heat-stable DNA polymerases, SW13 amplified a single 690-bp fragment linked to the I gene that more consistently permitted the identification of resistant plants. In addition, the presence of the I gene was detected using SW13 in genotypes originating from different gene pools of Phaseolus vulgaris L., indicating a broad utility of this marker for bean breeding programs. Key words : Phaseolus vulgaris, SCAR, RAPD, BCMV.
