Abstract:Loss of genetic diversity in elite crop breeding pools can severely limit long-term genetic gains, and limits gain for new traits that are becoming important as the climate changes, such as heat tolerance. Introgression of specific traits and pre-breeding germplasm is an alternative to introduce new diversity, however, introgression is typically slow and challenging. Here we use a genetic algorithm (GA) to select sets of parents which between them contain chromosome segments with very high segment breeding val… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research 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 students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
