Abstract

Groundnut is divided into two subspecies which differ in their branching pattern; sub sp. hypogaea with alternate branching and sub sp. fastigiata with sequential branching. Subspecies hypogaea is divided into two botanical varieties viz., hypogaea (virginia type) and hirsuta (peruvian runner type) and sub sp. fastigiata into var. fastigiata (valencia type) and var. vulgaris (spanish type). In present investigation genotypes of var. vulgaris were used.
