It is an important wide-spreading, herbaceous and annual legume pulse crop cultivated mostly by traditional farmers [2]. At present, mung bean cultivation spreads widely in Africa, South America, Australia and in many Asian countries [3]. The world annual production area of mung bean is about 5.5 million hectare with a increase in rate of 2.5% per annum [4].
