Rice bean Vigna umbellata (Thunb.) Ohwi and Ohashi] is an under exploited pulse crop having great potential for improvement as grain and fodder types. It requires more testing throughout the tropics, because of its tolerance to high temperature and humidity, short crop cycle, resistance to diseases and pests, nutritious seeds and multiple uses. Research priorities include development of quick maturing, day neutral, high yielding pulse and fodder type cultivars resistant to nematodes. Lack of awareness on potential nutritionally and economic use value of ricebean, improved varieties, less...

Mutation breeding is one of the innovative methods in plant breeding. Hugo de Vries introduced the term mutation in the late 19th century. Since the induction of artificial transmutation of gene by X-rays on Drosophila by Muller in 1927, the field of mutation breeding has gained improvement. Cowpea is an important food legume of the tropics and subtropics.Improvement of cowpea by conventional breeding techniques is time taking and involves constraints such as small flower, difficult crossing, poor seed setting and less number of seeds per pod. Mutation breeding in recent times as an effective...
