Two independent loci are shown to be concerned with the development of certain anthocyanin pigments throughout the plant body of diploid cultivated potatoes. A third locus is epistatic to these in its homozygous recessive phase and suppresses the development of pigment in the tuber only.
One pigment locus, designated
Two alleles of the other pigment locus, designated
An acylated derivative of peonidin occurs in all cultivated diploids, and in consequence no conclusions can be drawn about its inheritance. This anthocyanin is suppressed in the flowers only of genotypes homozygous for
Types of anthocyamdins other than petunidin occur only in cultivated potatoes but are similar in diploids and tetraploids. Presumably, this variability has been established by human selection at the diploid level and the evolution of tetraploidy was a later event in the genetic history of cultivated potatoes.
