A storage experiment was conducted to understand the effect of seed treatments on seed storage of three genotypes of paddy; NDR-359 (V₁), Vishnobhog (V₂) and Sahbhagi (V₃) at Seed Testing Laboratory, SHIATS Allahabad for 18 months during 2012-15. The three genotypes was taken from the seed Processing unit SHIATS, Allahabad and were treated with Neem Oil (T₁), Turmeric powder (T₂) and Carbendazim 12% (T₃) and T₀ was kept as control (untreated). The initial moisture content of paddy seeds was kept 13% which is a standard. The data were recorded on characters Viz: germination percentage, seedling vigour index, seed viability and field emergence after 18 months of storage. The effect of treatments on genotypes was significant on all characters after 18 months of storage. Mean comparison showed that the genotype NDR -359 (V₁) recorded significantly higher germination percentage (66.03%), seedling vigour index (953.89), seed viability (67.69%) and field emergence (59.91%) after 18 months. The treatment Carbendazim 12% (T₃) showed significantly better germination percentage (70.67%), seedling vigour index (1086.08), seed viability (72.83%) and field emergence (65.42%) after 18 months of storage period. The results indicates that the genotype NDR -359 (V1) treated with treatment Carbendazim 12% (T₃) was good in all quality characters.
