Abstract:AbstractThe common bean is characterized by high sensitivity to drought and low
productivity. Breeding for drought resistance in this species involves genes of
different genetic groups. In this work, we used a SEA 5 x AND 277 cross to map
quantitative trait loci associated with drought tolerance in order to assess the
factors that determine the magnitude of drought response in common beans. A
total of 438 polymorphic markers were used to genotype the F8 mapping
population. Phenotyping was done in two greenhous…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
