INHERITANCE OF CHLOROPHYLL DEFICIENCY IN INTRASPECIFIC CROSSES OF GROUNDNUT

Abstract

                                The study of F2 plants of intraspecific hybrid between sub sp. hypogace and sub sp. fastigiate of groundnut Arachis hypogaea L. showed the varying spectrum of chlorophyll deficient seedlings. The segregation pattern in F2 occurred in the ratio of 15:1 for green versus chlorophyll deficient seedlings, indicating the dihy- brid ratio controlled by duplicate factors. Since the ratio is identical in both direct and reciprocal crosses the influence of cytoplasm is ruled out. The spectrum of chlorophyll deficient seedlings consists of albina, viridis and chlorina.
