Abstract
THE anthocyanins of diploid cultivated potatoes (2n = 24) are controlled by at least two independent loci of which one, P, is epistatic to the other R1. Three closely linked loci, B, I and F, on another chromosome, are concerned with the distribution of pigment on the body of the plant. Locus I in its homozygous recessive phase ii is epistatic to the two colour loci and leads to the absence of pigment in the tuber, to which organ its main action is localized. Locus F governs the contrast between flecked and self-coloured flowers. The former are homozygous recessives, ff; they are mainly white, but show dashes of colour on and around the vascular ‘star’ which is characteristic of the corolla. Loci I and F have shown a recombination value of 1.98 ± 0.62 per cent.
