Abstract: Rational close planting is the important cultivation measure to achieve high yield and reasonable population structure. This article reviewed the influence of plant density on yield of wheat from grain yield, its components and population quality. These studies showed that: the effect of plant density on wheat yield and population quality indexes was significant. Plant density can coordinative the relations of the panicle per unit area, grain number per ear and 1000 grain weight to achieve high yield. It also controlled the changes of population structure effectively, to make it more reasonable.
