Abstract
Random inbred lines produced by doubled haploidy and single seed descent have been used to examine the effect of the GP ert locus on quantitatively varying characters in spring barley. In general the mean of the erectoides sub-population is lower than that of the corresponding nutans sub-population for characters such as thousand grain weight, main stem weight and single plant yield. Furthermore, allelic variation at the GP ert locus makes a large contribution to the additive genetic variation for a number of characters. A suitable strategy for the deployment of dwarfing genes in barley breeding programmes is discussed.
