Linkage and mapping of quantitative trait loci associated with angular leaf spot and powdery mildew resistance in common beans
Angular leaf spot (ALS) and powdery mildew (PWM) are two important fungi diseases causing significant yield losses in common beans. In this study, a new genetic linkage map was constructed using single sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs), in a segregating population derived from the AND 277 x SEA 5 cross, with 105 recombinant inbred lines. Phenotypic evaluations w...
متن کاملCommon bean reaction to angular leaf spot comprises transcriptional modulation of genes in the ALS10.1 QTL
Genetic resistance of common bean (Phaseolus vulgaris L.) against angular leaf spot (ALS), caused by the fungus Pseudocercospora griseola, is conferred by quantitative trait loci (QTL). In this study, we determined the gene content of the major QTL ALS10.1 located at the end of chromosome Pv10, and identified those that are responsive to ALS infection in resistant (CAL 143) and susceptible (IAC...
متن کاملQTL mapping for angular leaf spot in common bean using microsatellite markers
Linkage maps allow us to deepen the understanding of the genome of a species and the identification of genes or genomic regions, denominated QTL, which control traits of economical importance. The phenotypic expression of these genes can have a discrete or continuous distribution; in the latter case the trait is generally controlled by more than one gene. Among the markers applied for mapping t...
متن کاملGenome-Wide Association Studies of Anthracnose and Angular Leaf Spot Resistance in Common Bean (Phaseolus vulgaris L.).
The common bean (Phaseolus vulgaris L.) is the world's most important legume for human consumption. Anthracnose (ANT; Colletotrichum lindemuthianum) and angular leaf spot (ALS; Pseudocercospora griseola) are complex diseases that cause major yield losses in common bean. Depending on the cultivar and environmental conditions, anthracnose and angular leaf spot infections can reduce crop yield dra...
متن کاملQuantitative Trait Loci Associated with Drought Tolerance in Common Bean
Drought stress is the major limitation of common bean (Phaseolus vulgaris L.) grown in subsistence farming systems worldwide. The objective of this study was to use single nucleotide polymorphism (SNP) markers from the BARCBean6K_3 Beadchip to identify quantitative trait loci (QTL) associated with traits related to drought tolerance in common bean. An intergene pool recombinant inbred line (RIL...
