|Abstract: ||Poor and delayed seed germination is one of the major problems in papaya cultivation. Rapid loss of viability in storage is thought to be the major cause for poor germination. The effect of seed moisture, packaging materials and storage temperature on seed viability during storage was investigated in three varieties of papaya. The seeds were dried to various moisture levels, packed in polythene cover (700 gauge), aluminium poly pouches and Butter paper bags and stored under controlled conditions (15 0 C and RH 30%) and at ambient condition. The observations on seed germination and seedling vigour were recorded at 3-month intervals for 24 months. The results revealed that the seeds could be stored without any decline in viability and vigour for 24 months at 15 0 C irrespective of variety, packaging materials and seed moisture levels. However, under ambient conditions, the seeds of Surya could maintain high viability unto 15 months of storage, whereas Co-2 and Co-7 could maintain viability (>75%) unto 24 months with little decline in seed vigour. Among the packaging materials, poly lined aluminium pouches were found to be better and the seed moisture (5-10%) had no marked effect on viability.|
