Spatial Distribution, Diversity Mapping, and Gap Analysis of Wild Vigna Species Conserved in India’s National Genebank

The genus Vigna has several crop species that could be used to feasibly address nutritional security challenges in the subtropical and tropical regions of world, particularly climate-changing scenarios. Wild taxa are a source economically important traits need studied. Out 34 wild reported India, 928 indigenous accessions belonging 19 conserved India’s National Genebank (INGB) housed at Bureau Plant Genetic Resources, New Delhi. Geospatial mapping identified diversity-rich areas Western Ghats region exhibits highest Shannon diversity values (H = 1.65–3.0). Using complementarity procedure, six hotspots were for Vigna, these require utmost priority exploration germplasm collection. Due meagre amount information available BioClim model was successfully predict Idukki district Kerala as suitable site germplasm-collecting expeditions. Coastal rich twelve taxa, V. bourneae, dalzelliana, marina, sublobata, subramaniana, vexillata, stipulacea, trilobata, trinervia, immediate attention protect well collect from ex situ conservation. A hotspot protected forest Anshi Park Bhagwan Mahavira Wildlife Sanctuary an ideal spot possible conservation konkanensis, V silvestris, sublobata. 15 do not have representation INGB, 11 been endemic India. Priority needs given focussed This paper discusses future focus on explorations carried out collection species.
