Abstract
Freshly harvested and viable seeds sometimes fail to germinate because of dormancy. Glumes may prevent or delay the germination of viable seeds in several ways. This problem needs considerable attention in genebanks as it seriously interferes with germination test results, besides reducing germination during germplasm regeneration, resulting in preferential selection for less dormant types. Grain sorghum seeds [Sorghum bicolor (L.) Moench] show dormancy at harvest (Wilson 1973; Gaber et al. 1974) when tested for germination. However, seeds of other sorghum species (S. almum, S. intrans, S. halepense, S. stipodium and S. verticilliflorum) show considerably more dormancy than cultivated species. The sorghum germplasm collection (36,774 accessions) at ICRISAT’s genebank, Patancheru, India includes 417 accessions of 22 related wild species. Following International Genebank Standards, accessions with 85% or more viability were eligible for long-term storage (LTS). Hence, an attempt was made to find out the extent of factors affecting seed germination while processing sorghum germplasm for long-term storage.
