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 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 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.

Host Parasite

Abstract A diverse collection of seven Meloidogyne hapla isolates, all identified as cytological race A, were studied for their host-parasite interactions with several common bean (Phaseolus vulgaris L.) genotypes. The M. hapla isolates showed significant (P < 0.01) differential interactions of ability to reproduce on resistant common bean cultivars. Based on the nematode egg mass production on susceptible cv. Yolano and resistant cv. NemaSnap beans, the isolates formed three groups. Four isolates produced many egg masses on both susceptible and resistant cultivars and were defined as virulent to resistance in cv. NemaSnap. Two isolates produced many egg mass numbers on susceptible cv. Yolano, but very few on resistant cv. NemaSnap, and were defined as avirulent to the resistance in NemaSnap. One isolate, WI, produced fewer egg masses on susceptible cv. Yolano than on resistant cv. Nemasnap and was defined as virulent to resistance in cv. NemaSnap. The three types of host-parasite interaction indicated a transagonal reaction for a gene-for-gene relationship between M. hapla and resistant common bean (cv. NemaSnap). Analysis of an F2 population from crosses between cultivars NemaSnap and Yolano revealed a single dominant gene pattern of segregation for a major form of resistance in cv. NemaSnap. According to an allelism test, the resistance to M. hapla in cv. NemaSnap was not derived from the line PI165426, which is the pedigree source of M. incognita resistance in cv. NemaSnap. However, PI165426 was found to have M. hapla resistance but may not be homozygous for these factors.
