Clustering Anthocyanin Pigmentation Genes in Wheat Group 7 Chromosomes

Two bread wheat crosses were used to genetically map the genes determining anthocyanin pigmentation of the anther (Pan-D1), culm (Pc-B1 and Pc-D1), leaf sheath (Pls-B1), and leaf blade (Plb-B1, Plb-D1). The genes cluster with Rc-1 ( red coleoptile) on chromosome arms 7BS and 7DS. A germplasm panel of 37 wheat cultivars and introgression lines was tested for the presence of anthocyanin pigmentation on various plant organs, and significant correlations were established between pigmentation of the coleoptile and culm, coleoptile and leaf blade, coleoptile and anther, and anther and leaf blade.
