Abstract

Pulses occupy an important position in world agriculture because of their high protein content, several
essential amino acids and their capacity for fixing nitrogen. Winged bean (Psophocarpus tetragonolobus
(L.) DC.) is one of the most important pulse crop due to its nutritive value and property of maintaining
restoring soil fertility through biological nitrogen fixation. The nutritional value of the winged bean is
mainly due to the various positive attributes carried by its mature seeds. By keeping this view in mind, the
seeds of winged bean variety II-EC-178313 and 2I-EC-38825 were treated with chemical mutagens like
Ethyl Methane Sulfonate (EMS) and Sodium Azide (SA) separately. Mutagenic treatments resulted in
induction of nine types of viable promising mutants inM2 and M3 generations successively.These nine
mutants are early flowering, late flowering, early maturing, chlorina, linear leaflet, flat pod, long pod,
anthostem and high yielding. These mutants were analyzed for quantitative estimation of seed oil
content.This present research work is beneficial for development of improved varieties of winged bean for
oil yielding.
