Abstract:An experiment was conducted to study the genetics and nature of gene action of resistance to watermelon bud necrosis orthotospovirus (WBNV) in watermelon. The experimental materials comprised of two resistant (BIL‐53 and IIHR‐19) and one susceptible (IIHR‐140) parents. Each of the resistant parents was crossed with the susceptible parent to develop six generations (P1, P2, F1, F2, BC1 and BC2) to study genetics. The results of segregation in F2 and backcross progenies suggested that resistance is governed by a… 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.
