Induction of male sterility in winged bean [Psophocarpus tetragonolobus (L.) DC.]

Abstract

Utilization of male sterility in exploitation of hybrid vigour and population breeding has been helpful in achieving substantial yield gain in many crop plants. Hence, isolation of male sterile line is of prime importance in breeding programme. Occurrence of natural male sterile mutants is rare and if available these may be deficient in desirable character/so This has necessitated the artificial induction of male sterility by mutation or by use of selective gemetocidal compounds.
