554 Mapping of QTL for Seed Size and Shape Traits in Common Bean

Mapping of QTL for Seed Size and Sliape Traits in Common Bean

Bean seed weight and shape are important traits of different market bean classes. One of the first associations found between a genetic marker and a quantitative trait was reported by Sax ( 1923) for the relationship between seed pigmentation {P gene) and seed weight in common bean. More recently three types of molecular markers have been used to study the genetics of seed weight in common bean...

Bayesian QTL Mapping for Multiple Traits

QTL 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...

Meta-QTL for resistance to white mold in common bean

White mold, caused by the fungus Sclerotinia sclerotiorum (Lib.) de Bary, is a major disease that limits common bean production and quality worldwide. The host-pathogen interaction is complex, with partial resistance in the host inherited as a quantitative trait with low to moderate heritability. Our objective was to identify meta-QTL conditioning partial resistance to white mold from individua...
