Abstract
Field bean is one of the most important legume crops
of the world. Breeders are constantly occupied with the
improvement of existing varietiP.s as well as the introduction
of new ones. For a field b~~· variety to be successful
in agriculture it must be a high yielding, disease
resistant variety which also possesses high quality seed,
suitable for the different nutritional uses intended for
it..Furthermore it must be adapted to the environment whe:>.’
it is to be grown.
During the last 50 years or so and since .Miller’s
(1927), original paper on the induction of genetic chang-~
through X-irradiation, mutation breeding taken a place
along with traditional breeding methods in many parts of
the world.
There are several instances in the literature of
successful mutation breeding especially in the self-fertilizers.
Moreover, there ar.e nowadays many varieties of
different crops such as wheat, barley, peanut, sunflower.
etc. which are induced directlJ by mutagen treatme11t.
The main objective of this investigation is to ev<J.-
