Descriptors list used at NPGRL to characterize yard long bean (Vigna unguiculata ssp. sesquipedalis) accessions. The descriptor list created was based on IPGRI descriptors for mung bean, lima bean, Phaseolus vulgaris, Vigna aconitifolia, cowpea, and GRSU characterization datasheet for adzuki; and the RHS colour chart.
This is the unique identifier for accessions within a genebank, and is assigned when a sample is entered into the genebank collection
