Pollen storage allows more effacient use and handling of germplasm. This study was conducted for 3 yr to determine if longevity differed for pollen stored in screw-cap glass vials or reclosable plastic bags in a conventionaol r a frostless freezer. Viability of pearl millet [Pennisetum glaucum (L.) R. Br.] pollen stored in reclosable plastic bags was maintained for more than 1 yr in a frastless freezer, whereas pollen viability was lost within 1 yr when stored in a conventional frostforming freezer due to buildup of pollen moisture. Viability of pollen stored in screw-cap glass vials was maintained equally wall in both freezer types and lasted for more than 2 yr.
