Inheritance of light dependent purple pigmentation in chickpea

The inheritance of light dependent purple (LDP) pigmentation is worked out in the marked crosses of chickpea. The simple leaf, non-LDP line ICC - 10301 and Imperipinnate leaf, green line ICC - 32 were crossed by LDP pigmented, Imperipinnate leaf plants. The F₁ produced only LDP pigmented, Imperipinnate leaf plants in the two crosses. The F₂ segregated in two categories of LDP vs non LDP pigmented plants in a ratio of 9: 7, suggesting complimentary interaction of two genes. The simple leaf segregation was found to be 1: 3 with regard to Imperipinnate leaf, which is dominant.
