Markers: The OPAZ20 950 RAPD marker previously reported linked (7.1cM) to the Co-6 gene (Alzate-Marin et al, 2000), was also reported to be linked (2.2cM) to the co-8 in the cultivar AB 136 (Alzate-Marin et al, 2001b). The data also support the lack of independence of Co-6 and co-8.…”

Resistance to anthracnose in common bean is conditioned primarily by nine major independent genes, Co-1 to Co-10 as the Co-3/Co-9 genes are allelic. With the exception of the recessive co-8 gene, all other nine are dominant genes and multiple alleles exist at the Co-1, Co-3 and Co-4 loci. A reverse of dominance at the Co-1 locus suggests that an order of dominance exists among individual alleles at this locus. The nine resistance genes Co-2 to Co-10 are Middle American in origin and Co-1 is the only locus from the Andean gene pool. Seven resistance loci have been mapped to the integrated bean linkage map and Co-1 resides on linkage group B1; Co-2 on B11, Co-3 on B4; Co-4 on B8; Co-6 on B7; and Co-9 and Co-10 are located on B4 but do not appear to be linked. Three Co-genes map to linkage groups B1, B4 and B11 where clusters with genes for rust resistance are located. In addition, there is co-localization with major resistance genes and QTL that condition partial resistance to anthracnose. Other QTL for resistance may provide putative map locations for the major resistance loci still to be mapped. Molecular markers linked to the majority of major Co-genes have been reported and these provide the opportunity to enhance disease resistance through marker-assisted selection and gene pyramiding. The 10 Co-genes are represented in the anthracnose differential cultivars, but are present as part of a multi-allelic series or in combination with other Co-genes, making the characterization of more complex races difficult. Although the Co-genes behave as major Mendelian factors, they most likely exist as resistance gene clusters as has been demonstrated on the molecular level at the Co-2 locus. Since the genes differ in their effectiveness in controlling the highly variable races of the anthracnose pathogen, the authors discuss the value of individual genes and alleles in resistance breeding and suggest the most effective gene pyramids to ensure long-term durable resistance to anthracnose in common bean.

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.

Pigeonpea Sterility Mosaic Disease (PSMD) is an important foliar disease caused by Pigeonpea sterility mosaic virus (PPSMV) which is transmitted by eriophyid mites (Aceria cajani Channabasavanna). In present study, a F2 mapping population comprising 325 individuals was developed by crossing PSMD susceptible genotype (Gullyal white) and PSMD resistant genotype (BSMR 736). We identified a set of 32 out of 300 short decamer random DNA markers that showed polymorphism between Gullyal white and BSMR 736 parents. Among them, eleven DNA markers showed polymorphism including coupling and repulsion phase type of polymorphism across the parents. Bulked Segregant Analysis (BSA), revealed that the DNA marker, IABTPPN7, produced a single coupling phase marker (IABTPPN7414) and a repulsion phase marker (IABTPPN7983) co-segregating with PSMD reaction. Screening of 325 F2 population using IABTPPN7 revealed that the repulsion phase marker, IABTPPN7983, was co-segregating with the PSMD responsive SV1 at a distance of 23.9 cM for Bidar PPSMV isolate. On the other hand, the coupling phase marker IABTPPN7414 did not show any linkage with PSMD resistance. Additionally, single marker analysis both IABTPPN7983 (P<0.0001) and IABTPPN 7414 (P<0.0001) recorded a significant association with the PSMD resistance and explained a phenotypic variance of 31 and 36% respectively in F2 population. The repulsion phase marker, IABTPPN7983, could be of use in Marker-Assisted Selection (MAS) in the PPSMV resistance breeding programmes of pigeonpea.
