BackgroundGrain yield in wheat is a polygenic trait that is influenced by environmental and genetic interactions at all stages of the plant¿s growth. Yield is usually broken down into three components; number of spikes per area, grain number per spike, and grain weight (TGW). In polyploid wheat, studies have identified ...
