Varietal dataset of nutritionally important Lablab purpureus (L.) Sweet from Eastern Uttar Pradesh, India

Abstract

Legumes are one of the important crops for food and nutritional security. According to the International Treaty on Plant Genetic Resources for Food and Agriculture, the collection and documentation of promising germplasms are essential for creating the global database and also for facilitating the global exchange for crop improvement and further exploitation. Presented here are varietal dataset of an agriculturally important legume, Lablab purpureus (L.) Sweet, collected from eastern Uttar Pradesh of North India. Extensive field surveys were conducted for studying the occurrence and distribution of L. purpureus in six districts of eastern Uttar Pradesh (Ballia, Ghazipur, Jaunpur, Mirzapur, Sonebhadra and Varanasi) and germplasms of promising varieties were collected, and cultivated for further characterization. Dataset provides the morphological traits such as variation in stem colour, leaf size, flower colour, pod colour, pod size, seed size, seed weight etc. of fourteen different varieties of L. purpureus grown in the field gene bank maintained by authors at Rajgarh block of Mirzapur district, eastern Uttar Pradesh, India. Additionally, national and global distribution maps of L. purpureus was prepared using ArcGIS platform.
