“…The pinto bean cultivars Maverick and Othello and the navy bean cultivar Navigator were susceptible to race 73, confirming the results of del Rio et al (2003b). The cranberry bean Messina was resistant to race 73, which is similar to the reaction reported by del Rio et al (2003b) of the cranberry cultivar Taylor Horticultural.…”

The pinto bean cultivars Maverick and Othello and the navy bean cultivar Navigator were susceptible to race 73, confirming the results of del Rio et al (2003b).

“…Races 23 and 31 were included to distinguish cultivars that carry resistance genes Co-1 and Co-2 either separately or in combination. Race 73 is currently the prevalent race in Manitoba and Ontario (del Rio et al 2003b;Conner, unpublished data) and is virulent on any bean cultivar that carries genes Co-2 and Co-3 either alone or in combination. Race 81 is virulent on cultivars that carry genes Co-1 5 , Co-3 and Co-11 either alone or in combination.…”

L. M. 2008. Identification of anthracnose resistance genes in dry bean cultivars grown in Manitoba. Can. J. Plant Sci. 88: 771Á781. Previously described random amplified polymorphic DNA (RAPD) and sequence characterized amplified region (SCAR) markers were used to identify specific genes for anthracnose resistance in 20 dry bean (Phaseolus vulgaris) cultivars and one breeding line. These included six navy bean, five black bean, three kidney bean, two great northern bean, two pinto bean, one cranberry bean, one pink bean and one small red bean cultivars. The reactions of these bean cultivars to five races (i.e., races 23, 31, 73, 81, 105) of Colletotrichum lindemuthianum were used to verify the results of the molecular marker tests. The combined analysis of genotypes estimated with markers and race reactions showed that navy bean cultivar Envoy carried gene Co-1 2 , possibly in combination with other resistance genes, which conferred resistance to all the races except race 105. The bean cultivars Morden003, Messina and CDC Nordic carried Co-1 5 , which provided resistance to only races 73 and 105. Resistance in AC Mariner appeared to be controlled by gene Co-2 either alone or possibly in combination with Co-11. The kidney bean cultivars Chardonnay and ROG 802 carried resistance gene Co-1. Eight other cultivars were resistant to races 23 and 31, which indicated that they carried resistance gene Co-3 or another unidentified resistance gene. Six dry bean cultivars were susceptible to all five anthracnose races. Genotype estimates were based primarily on the virulence pattern of the races on specific cultivars. The results from the molecular tests sometimes supported the proposed genotypes based on the results from the race inoculations, but false positive results often occurred with molecular markers for genes Co-2 and Co-4. Virulence pattern information allowed the detection of specific resistance genes in certain cultivars, but did not always rule out the presence of other genes. , qui les prote`ge des races 73 et 105. La re´sistance de AC Mariner semble code´e par le ge`ne Co-2, seul ou e´ventuellement avec le ge`ne Co-11. Les cultivars de haricot rognon Chardonnay et ROG 802 portent le ge`ne de re´sistance Co-1. Huit autres cultivars re´sistaient aux races 23 et 31, signe qu'ils portent le ge`ne de re´sistance Co-3 ou un autre, non identifie´. Six cultivars e´taient sensibles aux cinq races d'anthracnose. Les estimations du ge´notype s'appuyaient essentiellement sur la virulence des races pour les cultivars indique´s. L'issue des essais mole´culaires confirme parfois les hypothe`ses sur le ge´notype re´sultant de l'inoculation

“…The extensive virulence diversity of the ALS pathogen suggests that common bean cultivars with single genes for resistance to ALS will likely succumb to new virulent races of the ALS pathogen in the future. This has frequently been observed in bean cultivars harboring single genes for resistance to the rust and anthracnose pathogens (Kelly et al, 1994;del Río et al, 2003;Pastor-Corrales et al, 2010). In addition, there is ample evidence that the virulence diversity of the ALS pathogen is changing.…”

Angular leaf spot (ALS), caused by Pseudocercospora griseola, is one of the most devastating diseases of common bean (Phaseolus vulgaris L.) in tropical and subtropical production areas. Breeding for ALS resistance is difficult due to the extensive virulence diversity of P. griseola and the recurrent appearance of new virulent races. Five major loci, Phg‐1 to Phg‐5, conferring ALS resistance have been named, and markers tightly linked to these loci have been reported. Quantitative trait loci (QTLs) have also been described, but the validation of some QTLs is still pending. The Phg‐1, Phg‐4, and Phg‐5 loci are from common bean cultivars of the Andean gene pool, whereas Phg‐2 and Phg‐3 are from beans of the Mesoamerican gene pool. The reference genome of common bean and high‐throughput sequencing technologies are enabling the development of molecular markers closely linked to the Phg loci, more accurate mapping of the resistance loci, and the comparison of their genomic positions. The objective of this report is to provide a comprehensive review of ALS resistance in common bean. Furthermore, we are reporting three case studies of ALS resistance breeding in Latin America and Africa. This review will serve as a reference for future resistance mapping studies and as a guide for the selection of resistance loci in breeding programs aiming to develop common bean cultivars with durable ALS resistance.

“…Bean cultivars can be resistant to specific races; however, the introduction of new races into a growing region can place existing cultivars at risk (Chase 1987;Conner et al 2006). Currently, Race 73 of anthracnose is the predominant race in Canada, first confirmed in Manitoba in 2001(Del Rio et al 2003 and then Ontario in 2003. The most effective disease-prevention tool is to plant certified disease-free seed and to plant cultivars resistant to anthracnose races common in the locality (Dillard and Cobb 1993), but most navy bean cultivars in Canada are susceptible to Race 73 (Navabi et al 2012).…”

Transmission of anthracnose (Colletotrichum lindemuthianum) in dry bean (Phaseolus vulgaris L.) with artificial and natural inoculum in a wet and dry canopy

LeClair, E., Conner, R., Robinson, D. and Gillard, C. L. 2015. Transmission of anthracnose (Colletotrichum lindemuthianum) in dry bean (Phaseolus vulgaris L.) with artificial and natural inoculum in a wet and dry canopy. Can. J. Plant Sci. 95: 913–921. Anthracnose [Colletotrichum lindemuthianum (Sacc. and Magn.) Lams. – Scrib.] is a serious pathogen of dry bean (Phaseolus vulgaris L.). Disease transmission on artificial materials and clothing has been observed in other crops, where equipment and workers transmit pathogens from infected to clean plants. Initial studies in 2008 and 2009 at Exeter, ON, determined that anthracnose transmission in dry bean as measured by resultant disease severity occurred with denim, leather, metal, and rubber using a 107 spores mL−1 prepared artificial spore inoculum in both wet and dry crop canopies. In 2012 and 2013 at Morden, MB, and Ridgetown, ON, the studies were expanded by adding a 105 spores mL−1 prepared artificial and a natural inoculum source. Inoculum source and canopy moisture had the greatest effect on disease severity, while no differences were observed between materials within an inoculum sources. Transmission in wet canopy conditions resulted in a higher infection rate. Canopy moisture impacted the natural inoculum the most. The 107 spores mL−1 inoculum transmitted the most disease followed by natural incidence and 105 spores mL−1 inoculum in wet conditions. In dry conditions 107 spores mL−1 inoculum transmitted the most disease followed by 105 spores mL−1 inoculum and natural incidence. Producers need to recognize that there is real risk for the anthracnose transmission by common materials in dry bean, and take appropriate precautions to prevent it.
