The Anthracnose, caused by Colletotrichum lindemuthianum (Sacc. and Magnus) Briosi and Cavara, is one of the most importante fungal disease of common bean. Several strategies have been used for its control, such as the use of pathogen-free seeds, chemical control and crop rotation. However, the most efficient method to control this disease is the use of resistant cultivars. Previous studies conducted by the Laboratory of Common Bean Breeding and Molecular Biology of the Nucleus of Research Applied to Agriculture (Laboratório de Melhoramento de Feijão Comum e de Biologia Molecular do Núcleo de Pesquisa Aplicada à Agricultura-NUPAGRI) revealed that the Andean cultivar Amendoim Cavalo is resistant to races 2, 7, 9, 19, 23, 39, 55, 65, 73, 89, 1545, 2047 and 3481 of C. lindemuthianum. The objective of this work was to characterize the genetic resistance to anthracnose in Amendoim Cavalo using inheritance and allelism tests. The results of inheritance tests in F2 generation of Amendoim Cavalo × PI 207262 cross, inoculated with 2047 race, fitted in a ratio of 3R:1S, proving the action of a single dominant gene in Amendoim Cavalo cultivar. Allelism tests demonstrated that the dominant gene present in Amendoim Cavalo is independent from the genes previously characterized. The authors propose the Co-AC symbol to designate the new resistant gene to C. lindemuthianum. The results show high contribution to breeding programs, once Amendoim Cavalo cultivar can be considered an important Andean source of resistance to C. lindemuthianum.

The anthracnose caused by fungus Colletotrichum lindemuthianum (Sacc. & Magnus) Briosi & Cavara is the most widespread disease and economically important fungal disease of common bean (Phaseolus vulgaris L.). The use of resistant cultivars is considered as one of the most effective methods in controlling this disease. The present study had as aim to characterize the genetic resistance of the Andean common bean cultivar Jalo Pintado 2 to the C. lindemuthianum through inheritance and allelism tests. The experiment was conducted under greenhouse conditions at Laboratório de Melhoramento do Feijão Comum e de Biologia Molecular do Núcleo de Pesquisa Aplicada a Agricultura (Nupagri) at Universidade Estadual de Maringá, Paraná, Brazil. The results of the F2 population from the crossing 'Jalo Pintado 2' (R) × Cornell 49-242 (S), inoculated with race 73 of C. lindemuthianum, adjusted to the ratio of 3R: 1S, demonstrating the action of a dominant gene in the cultivar Jalo Pintado 2. The allelism tests evidenced that the gene in the 'Jalo Pintado 2' is independent from those previously characterized: Co-1, Co-2,Co-3, Co-34, Co-4, Co-42, Co-43, Co-5, Co-6, Co-11, Co-12, Co-13, Co-14, Co-15 and Co-16. This gene is also independent from those genes not yet named present in Paloma, Perla and Amendoim Cavalo cultivars. The authors propose the Co-

The Common

Anthracnose, which is caused by the fungus Colletotrichum lindemuthianum, is one of the most widespread and important diseases of the common bean (Phaseolus vulgaris L.) in the world. The objective of the present study was to characterize the genetic resistance of the Beija Flor cultivar by inheritance and to conduct allelism tests. The inheritance test was conducted in the F2 population derived from the Beija Flor (resistant) x TU (susceptible) cross inoculated with race 2047 of C. lindemuthianum. Furthermore, allelism tests exhibited a fitted segregation ratio of 15R:1S, thereby indicating the independence of the Beija Flor gene from the following previously characterized genes: Co-1, Co-2, Co-4, Co-42, Co-6, Co-12, Co-14, Co-15, and Co-Pe. Based on the aforementioned results, we are proposing the symbol Co-Bf to designate the new anthracnose resistance gene in the Brazilian Andean common bean cultivar Beija Flor. This cultivar is an important source of resistance to C. lindemuthianum that should provide a valuable contribution to the common bean breeding program for anthracnose resistance.

The pathogenic variability of the fungus Colletotrichum lindemuthianum represents an obstacle for the creation of resistant common bean (Phaseolus vulgaris L.) varieties. Gene pyramiding is an alternative strategy for the development of varieties with durable resistance. RAPD markers have been proposed as a means to facilitate pyramiding of resistance genes without the need for multiple inoculations of the pathogens. The main aims of this work were to define the inheritance pattern of resistance present in common bean cultivar AB 136 in segregating populations derived from crosses with cultivar Rudá (susceptible to most C. lindemuthianum races) and to identify RAPD markers linked to anthracnose resistance. The two progenitors, populations F1 and F2, F2:3 families and backcross-derived plants were inoculated with race 89 of C. lindemuthianum under environmentally controlled greenhouse conditions. The results indicate that a single dominant gene, Co-6, controls common bean resistance to this race, giving a segregation ratio between resistant and susceptible plants of 3:1 in the F2, 1:0 in the backcrosses to AB 136 and 1:1 in the backcross to Rudá. The segregation ratio of F2:3 families derived from F2 resistant plants was 1:2 (homozygous to heterozygous resistant). Molecular marker analyses in the F2 population identified a DNA band of approximately 940 base pairs (OPAZ20(940)), linked in coupling phase at 7.1 cM of the Co-6 gene. This marker is being used in our backcross breeding program to develop Rudá-derived common bean cultivars resistant to anthracnose and adapted to central Brazil.

Colletotrichum lindemuthianum, the causal pathogen of common bean (Phaseolus vulgaris) anthracnose, is highly variable. Therefore, understanding its race structure and identification of new sources of resistance is necessary for the development of varieties with durable resistance. The objectives of this study were (i) to characterize isolates of C. lindemuthianum collected from three major bean-growing regions in Zambia, and (ii) evaluate the CIAT Phaseolus core collection for resistance to C. lindemuthianum races 37, 73, and 566, and a blend of 20 races. Isolates collected from three major bean-growing districts in Zambia, namely Mporokoso, Mpika, and Mbala, were characterized as race 37, 73, and 566, respectively. A subset of the CIAT core collection comprised of 885 accessions of common bean, 13 accessions of scarlet runner bean (P. coccineus), and 11 accessions of year bean (P. dumosus) were evaluated for resistance to races 37, 73 and 566, and a blend of 20 races in a greenhouse at University of Zambia, Lusaka, Zambia. A total of 72%, 66%, 48% and 9% of P. vulgaris accessions evaluated were highly resistant to races 37, 73, 566 and a blend of 20 races, respectively. Also, accessions of P. coccineus and P. dumosus, highly resistant to races 37, 73 and 566, were identified. Only eight of the 331 P. vulgaris accessions were highly resistant to all three individual races (37, 73, and 566) and to a blend of 20 races. These eight accessions constitute a valuable breeding resource for developing varieties with durable resistance to C. lindemuthianum.

The INIFAP (Instituto Nacional de Investigaciones Forestales y Agropecuarias) herbarium specimens of Phaseolus spp. collected in Mexico during the period from 1978 to 1991 were examined with the aim of increasing our knowledge on the distribution of the insects and diseases that attack those species. A total of 775 specimens, including 24 different Phaseolus species from different regions of Mexico, were studied. Based on visual symptoms of pathogen damage, a wide geographic distribution of diseases and insects was observed in almost all species; most of them are the same pathogens that attack the cultivated common bean (P. vulgaris). It is possible to find genetic resistance to pathogens in the wild Phaseolus spp., resistance that may be useful to improve the cultivated forms in the genus. However, the utilization of germplasm of wild Phaseolus species will depend upon the thorough characterization of those species, their compatibility with the cultivated beans, and the inheritance of the traits involved.

Seed Phenotype

Anthracnose, caused by Colletotrichum lindemuthianum, is one of the most serious diseases of common bean (Phaseolus vulgaris). The pathogenic variability of this fungus in northern Spain and the response of a bean germplasm collection maintained at Servicio Regional de Investigación y Desarrollo Agroalimentario (Villaviciosa, Asturias, Spain) were screened in order to identify potential resistance sources. Races 3, 6, 19, 38, and 102 were identified from 55 isolates collected in this area, race 38 being the most common one. In all, 246 landraces and 42 lines derived from breeding programs were evaluated in search of resistant lines. No local accession showed adequate resistance to the five races. However, three local accessions were resistant to four races and presented intermediate or mixed reactions against the fifth one: accession V225, with a large great northern seed phenotype (R3R6I38R102R19); accession V369, with a great northern seed phenotype (R3R6R38R102R/S19); and accession V309, with a navy seed phenotype (R3R6R38R/S102R19). The results revealed a wide variation in the resistance spectra or resistance combinations, although not all the possible resistance spectra were present in the evaluated accessions. Among the breeding lines, nine materials were resistant to five races and three lines (A252, A321, and A493) were selected as resistance sources to transfer genetic resistance to Andecha bean cultivar. The results indicated that lines A252 and A321 have two dominant and independent genes involved in the resistance to race 38 whereas line A493 has a single locus.
