Rice Bean (Vigna umbellata) – A Potential Legume under Adverse Conditions

Rice bean is an underutilized legume crop that comes up with many benefits i.e., dried pulse, fodder and green manure thus helps in human, animal nutrition environmental health. It a resilient plant resistant to variety of diseases pests especially the Bruchids, it can be grown well less fertile, exhausted, degraded lands drought prone sloping areas; along these, contains genes for biotic abiotic stress tolerance, including drought, soil acidity tolerance Aluminum ions. Waterlogging shows greater negative impact on crops legumes by reducing photosynthesis, growth, grain yield; formation, function survival nodules, biological nitrogen fixation, may even causes death severe waterlogged conditions. An insufficient supply or carbohydrates thought have hampered flowering life recovery. at any stage has detrimental seed output. Depending conditions, flooding range from transient permanent. Based sort regime habitat, different species, genotypes same choose avoidance, escape, quiescence strategies overcome stress, among these coping options follow morphological alterations escape mechanism. As thrive adverse conditions once exact reason behind this explored, feature used breeding programs improvement.
