Abstract:Introducing variations in inflorescence architecture, such as the 'Miracle-Wheat' (Triticum turgidumconvar.compositum(L.f.) Filat.) with a branching spike, has relevance for enhancing wheat grain yield. However, in the spike-branching genotypes, the increase in spikelet number is generally not translated into grain yield advantage because of reduced spikelet fertility and grain weight. Here, we investigated if such trade-offs might be a function of source-sink strength by using 385 RILs developed by intercross… Show more
scite is a Brooklyn-based startup 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.
