The study was conducted to investigate the effects of storage temperature and storage period on seed viability of a wheat variety, Rawal-87. The seed moisture content and seed viability were determined in control which were 8.0 per cent and 90 per cent respectively. The interaction among storage period and storage temperature was statistically significant. In wheat, the maximum seed viability was observed at -20 and 5 degree centigrade after 12 months storage. A decline in germination percentage was observed at 50 degree centigrade after 4 months. Germination per cent age was higher when petri dishes were used for germination tests. During germplasm storage of wheat, storage temperature and storage period play an important role.
