Seed ageing is influenced by two factors moisture and temperature. The deterioration of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. The present study was carried out in the Department of Seed Science and Technology Section, CCS Haryana Agricultural University, Hisar, India. This study aimed at evaluating efficiency of different pickings of cotton seed vigor potential during storage. Thereby, three American cotton varieties H-1098 (I), H-1117 and H-1236 were taken into account, were picked at different intervals and after ginning and delinting, initial seed vigor evaluation was done and seeds were stored under controlled condition at 200 C with 6 per cent moisture content for fifteen months. Evaluations of germination per cent, seedling length, seedling weight, vigor indices were performed after five, ten and fifteen months of storage (5, 10, 15 months). It was observed that seed samples of second pick stored seed showed higher vigor followed by first pick stored sample whereas minimum was recorded under third pick stored sample.
