Popovsky, I. Paran] Abstract : Classical genetic studies have determined that the yellow fruit color in pepper is recessive to red in the locus y. We studied the relation of the y locus with the gene coding for capsanthin-capsorubin synthase (CCS) that synthesizes the red carotenoid pigments in the mature fruit. Cosegregation of y and CCS in populations derived from crosses between plants bearing red×white and red×yellow fruits indicated the correspondence of the two genes. We obtained indications for the occurrence of a deletion in the CCS gene in plants containing the recessive y allele. This deletion did not contain the distal 220 bp of the 3′ end of the gene. We used the CCS gene to determine the genotype of peppers with different fruit colors at the y locus. In BC1 segregants from a red×white cross, the red and peach-fruited progenies had the wild-type allele at the CCS locus, while the orange, yellow and white-fruited progenies had the mutant allele. Screening orange-fruited cultivars with CCS as well as segregation analysis of CCS in an additional red×white cross indicated two possible genotypes of the orange fruit color in this locus.
