Linkage mapping of the Phg-1 and Co-1 genes for resistance to angular leaf spot and anthracnose in the common bean cultivar AND 277
The Andean common bean AND 277 has the Co-1 and the Phg-1 alleles that confer resistance to 21 and eight races, respectively, of the anthracnose (ANT) and angular leaf spot (ALS) pathogens. Because of its broad resistance spectrum, Co-1 is one of the main genes used in ANT resistance breeding. Additionally, Phg-1 is used for resistance to ALS. In this study, we elucidate the inheritance of the ...
متن کاملAre duplicated genes responsible for anthracnose resistance in common bean?
The race 65 of Colletotrichum lindemuthianum, etiologic agent of anthracnose in common bean, is distributed worldwide, having great importance in breeding programs for anthracnose resistance. Several resistance alleles have been identified promoting resistance to this race. However, the variability that has been detected within race has made it difficult to obtain cultivars with durable resista...
متن کاملMapping and Genetic Structure Analysis of the Anthracnose Resistance Locus Co-1HY in the Common Bean (Phaseolus vulgaris L.)
Anthracnose is a destructive disease of the common bean (Phaseolus vulgaris L.). The Andean cultivar Hongyundou has been demonstrated to possess strong resistance to anthracnose race 81. To study the genetics of this resistance, the Hongyundou cultivar was crossed with a susceptible genotype Jingdou. Segregation of resistance for race 81 was assessed in the F2 population and F2:3 lines under co...
متن کاملCandidate Gene Identification with SNP Marker-Based Fine Mapping of Anthracnose Resistance Gene Co-4 in Common Bean
Anthracnose, caused by Colletotrichum lindemuthianum, is an important fungal disease of common bean (Phaseolus vulgaris). Alleles at the Co-4 locus confer resistance to a number of races of C. lindemuthianum. A population of 94 F4:5 recombinant inbred lines of a cross between resistant black bean genotype B09197 and susceptible navy bean cultivar Nautica was used to identify markers associated ...
متن کاملNew Insights into the Anthracnose Resistance of Common Bean Landrace
The common bean landrace G 2333 carries a three gene pyramid for anthracnose resistance: Co-4 2 , Co-5 and Co-7. The Co-4 2 gene is well characterized but less information is available on Co-5 and Co-7. The objectives of this study were to determine if a new allele of Co-5 is present in G 2333; to characterize the spectrum of resistance conditioned by the Co-7 gene by deriving lines which only ...
