A study was conducted to evaluate seed longevity of 15 mung bean [Vigna radiata (L.) Wilczek] genotypes, including IPM-2-3, PDM-139, IPM-2K-14-9, IPM 409-4, IPM 410-3, IPM 312-20, IPM 512-1, IPM 302-2, IPM 16-20-6, IPMD 2-802, IPMD 19-05, IPM-2-14, IPM 205-7, DGGV-2, and IPM 1604-1, which were stored under ambient conditions for six months and categorized as good, medium, and poor storers based on the observed physiological changes in seeds during the storage period. The results showed that as the storage period progressed, there was a noticeable decline in seed quality parameters, with freshly harvested seeds exhibiting higher germination and vigour. After six months of storage, good storers (IPM 205-7, IPM 512-1, IPMD 19-05, and IPM 409-4) maintained higher germination, seedling vigour indices, and lower electrical conductivity of seed leachate compared to poor storers (IPM-2K-14-9, IPM 16-20-6, and IPM 1604-1). Additionally, an increase in seed moisture content and electrical conductivity was observed due to metabolic reserve depletion, contributing to the reduction in seed vigour and viability.
