The association of genes for purple pigment in the coleoptile with the chromosomes of the winter wheat variety Mironovskaya 808 was investigated using monosomic F2 analysis. The segregation ratio for F2 hybrids of Chinese Spring monosomics x Mironovskya 808 seems to indicate that the purple colour of the coleoptile is determined by two dominant genes, Rc3 and Rc4, which are located on the chromosomes 7D and 6B respectively, and which reinforce each other. Apart from these two genes, suppressors found on the chromosomes 2A, 2B, 2D, 4B and 6A also play a role in the intensity of the purple colour. With the aid of a Chinese Spring telocentric chromosome marker it was observed that the Rc3 gene is located on the chromosome arm 7DS, at a distance of 16±4.23 crossover units from the centromere.
