Inheritance studies with flower colour in Cicer showed that pink and white colours were differentiated by a single factor pair which was designated as Pp. This factor pair was inherited independently from seven other factor pairs controlling the expression of Tiny Leaf, Stalked Leaflet, Bushy, Double Flower, Giant, Simple Leaf and Flat Stem mutants. However, Pp locus showed a close linkage with the locus responsible for the Round Pod mutant (Rprp), the cross over frequency between the two loci being 2.6 per cent.
