In the present investigation, the two chemical mutagens namely Ethyl methanesulfonate (EMS) and Sodium azide (SA) were used to induce mutations in winged bean (Psophocarpus tetragonolobus (L.) DC.). Winged bean is a potential legume crop of the tropics with high protein and oil content in the seeds. For larger scale cultivation however, the major drawbacks possessed by winged bean should be minimized. The drawbacks such as presence of undesirable antinutritional factors, absence of market demands and labour intensive nature of crop.Hence its production and productivity need to be improved from the present level. A mutation breeding programme was undertaken with the objective of developing improved varieties of winged bean so that it can be popularized among the farmers for its cultivation over large areas. Thus in the present studies, attempts have been made to induce mutations in winged bean and to find out the effect of EMS and SA on seed germination percentage in M1 generation.
