Germplasm characterization in indigenous blackgram (Vigna mungo (L.) Hepper)

Three hundred twenty indigenous accessions, collected from diversity zones of Uttar Pradesh, were evaluated for 10 quantitative and 25 visual characters in incomplete block design, augmented with 4 checks. The characters, seed yidd per m², pods per cluster and pods per plant exhibited high variability while the remaining seven traits, plant height, pod length, 100-seed weight, seeds per pod, days to flowering, relative chlorophyll index and days to maturity. showed moderate to low variability. Full range of variability was observed for all the visual characters. About 60 and 10% accessions exhibited resistance reaction to yellow mosaic and leaf crinkle vims diseases, respectively.
