A note on distribution and potential of Japanese wild adzuki bean [Vigna angularis var. nipponensis (Ohwi) Ohwi and H. Ohashi] in India

The present paper deals with the report on the potential of Vigna angularis var. nipponensis (Ohwi) Ohwi and H. Ohashi assembled from Northeastern hill region (NEH) of India. The total of four exploration missions were conducted in remote and highaltitude areas of Nagaland, Arunachal Pradesh and Mizoram during 2011, 2016, 2017 and 2019 to confirm the occurrence, localities of new distribution and genetic resource study. Preliminary studies on seed germination and morpho-nutritional evaluation of seed of both cultivated and wild forms were also conducted. Conserving precious germplasm of this less represented wild relative of adzuki bean { Vigna angularis (Willd.) Ohwi and Ohashi} assumes great significance for its use in breeding and improvement of Vigna crop group.
