Inheritance of main axis flowering and seed testa colour in groundnut (Arachis hypogaea L.)

Abstract

Variability in testa colour of groundnut is considerable from white, tan, rose, pink, wine red to deep red. The commercially accepted colours are rose and red both to the consumers as well as millers. On the other hand, main axis flowering in groundnut is one of the important criteria used for classifying the species hypogaea into two sub-species viz., hypogaea and fastigiata [1-2]. Different types of gene actions have been reported for inheritance of testa colour and main axis flowering by different workers [3]. In the present investigation the inheritance of these two traits has been discussed.
