Common bean lines reaction to the anthracnose pathogen

New 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 ...

Are 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...

First Report of Colletotrichum fructicola as the causal agent of Anthracnose on Common Bean and Cowpea

Reaction of common bean lines and aggressiveness of Sclerotinia sclerotiorum isolates.

The aims of this study were to evaluate the reaction of common bean lines to white mold, the aggressiveness of different Sclerotinia sclerotiorum isolates from various common bean production areas in Brazil, and comparison of the diallel and GGE (genotype main effect plus genotype-by-environment interaction) biplot analysis procedures via study of the line-by-isolate interaction. Eleven common ...
