Inheritance of pigmentation in leaf axil, petiole, midrib and veins in cowpea

Abstract

Inheritance of four characters namely pigmentation in axil, petiole, midrib and veins in cowpea was studied in a cross Virginia x TVX 2112. An unusual ratio of 39:25 was obtained for axil and 3:13 for petiole, midrib and veins. A basic pleiotropic gene (Px) was detected in these characters. The inheritance pattern on these characters was studied for the first time and the genie symbols were given.
