Abstract

The North Central Regional Plant Introduction Station (NCRPIS), located at Iowa State University in Ames, is one of the primary sites of the U.S. National Plant Germ plasm System (Roath et al., 1990; White et al., 1989). The NCRPIS specializes in the management of germplasm of agronomic and horticultural crops and their wild relatives that are primarily allogamous (outbreeding). Each year, crop~specific curators at the NCRPIS regenerate seeds of hundreds of germplasm accessions in the field and under glass, controlling pollination to preserve the genetic integrity of the collections. Pollinations for some crops, such as pumpkins, domesticated sunflowers, and corn, are made by hand. A few others, such as amaranths and chenopods, can be regenerated in plastic tents without special pollinators (Williams and Brenner, 1995), provided there is some air movement in the tents. But most crops maintained at the NCRPIS are insect pollinated in nature and their flowers are tedious to pollinate by hand.
