INHERITANCE OF CRESENT COLOUR ON STANDARD PETAL IN GROUNDNUT (Arachis hypogaea L./

Abstract

The study of F2 plants of intraspecific hybrid between the varieties having purple veins in the standard petal and varieties lacking the purple colour showed a segregation in the ratio of 3:1 for purple colour and for its absence. Hence it is evident that the character is governed by single dominant gene. Since the ratio is identical in both direct and reciprocal crosses, the influence of cytoplasm is tuled out.
