So the key is dry, dry, dry.Flue cured tobacco seed var. CTRI Spl and White gold of crop season 1975-76 was stored at
ambient temperature in 500g capacity container with and without desiccant, anhydrous calcium chloride.
Seed stored with 5-6% and lower than 3% initial seed moisture with desiccant (dry storage) maintained
viability and the moisture content was below 4.5% for a period of 24 years (March 2000) whereas seed
stored without desiccant (control) contained seed moisture of 6-7% and lost viability,in 24 months. To
adopt this method for tobacco seed storage in large scale CTRI Spl (MR) of crop season 1982-83 was
stored in 50 kg drums with desiccant (250 and 500g) at ambient temperature. and the seed remained
viable for 17 years (March 2000), Seed stored without desiccant lost viability in 24 months and its seed
moisture was 6-7%. Stored seed was tested in nursery for seedling production and it was at par with
fresh seed. It is concluded that storage of tobacco seed at ambient temperature using desiccant.'is
reliable and inexpensive method as compared to traditional method of cold storage for long term
tobacco seed storage.
