Abstract: Radish is an important root vegetable crop widely cultivated for its tender roots as well as succulent foliage and immature pods (used largely in salad and for culinary purposes). The plant is propagated through seeds. The information on storability as well as on extent of recovery of quality seeds on conservation is inadequate. Seeds of cv Pusa Reshmi were preserved in moisture permeable, semi-impermeable and impermeable containers under different storage conditions for 25 years. Seed longevity significantly improved from 2 to 25 years under controlled storage conditions which helped to maintain high seed quality for 25 years. The percentage of seed germination at 5°C and –20°C was 88 in seeds stored in moisture impervious container. Seeds stored at 5°C in moisture semi-impermeable containers also showed fairly high viability (79%), while seeds succumbed to chilling injury when stored in moisture permeable containers. The extent of recovery of viable seeds was 89 per cent at 5°C and 88 per cent at –20°C storage after 25 years of storage. Seedlings emerged from stored seeds were normal, healthy, vigorous and free from morphological abnormalities. Seed storage in laminated aluminium foil pouches at 5°C was effective as well as cost-effective in maintaining high viability (89%) for a long period (25 years) and useful in germplasm conservation thereby avoiding frequent cultivation of the crop and its genetic erosion.
