Genetic resources (GR) are gene and diversity source which has to be preserved or conserved. Seed genebank is an ex situ conservation facilities which may efficiently ensure the availability of the genetic materials of such resources. In order to accomplish this mission, genebank have to monitor periodically the seed quality within the GR collection. Our study aimed to observe the seed viability of mungbean collection in IAARD genebank. A total of 107 mungbean accessions from various years of storage (1999–2013) were randomly chosen to be tested their seed viability. The result showed that 56 accessions had high viability (>80%) and 26 accessions had low viability (<30%). Surprisingly, newer years of seed production (2003–2004) showed lower viability compared to those from older years. Information and analysis resulted from this study may identify the weakness from the existing conservation strategy. Moreover, a better strategy for seed conservation in the future could be developed, thus a good quality of seed could be obtained and prolonged the storaging.
