Inheritance study of some morphological traits in castor (Ricinus communis L.)

Abstract

The study revealed that green spike colour epistatic over sulphur white colour and trait being governed by a dominant inhibitory gene and another colour gene (Sulphur white). Monogenic nature of inheritance was observed for the other characters viz. nature of inter nodes, stem colour, and presence of bloom. Joint segregation for different pair of traits suggested independent segregation of all the traits studied and no evidence of linkage was detected.
