Abstract : Pollen germination capacity and viability of 3-mango cultivars viz., Chaunsa, Dasheri and Langra were investigated up to 48 weeks. Pollen germination was standard by hanging drop technique in different concentration of sucrose solutions (5%-50%) with 1% agar and 0.001% boric acid. The stored conditions were refrigerator (4°C), freezer (-20°C, -30°C), freeze drier (-60°C), in vacuum over silica gel and in organic solvents (acetone, benzene, chloroform). Pollen stored at low temperature showed better germination percentage compared to pollen stored at 4°C and fresh. Among three cultivars variety langra showed better pollen germination at all stored conditions except at -20°C. Variety chaunsa and dasheri also showed good germination of pollen.
