Development of pre‐variety germplasm of Canadian native grassland species

摘要：

Seed of native Canadian grassland species is being increasingly required for conservation and reclamation plantings in the great plains region of Canada.Cultivars of a few grass species have been available since the 1970s, but for most species,seed has often been from non-adapted sources,or simply not available.To rectify this problem,collaborations were established in the early 1990s between a conservation organization,Ducks Unlimited Canada (DUC),and plant breeders at Agriculture and Agri-Food Canada (AAFC) and the University of Manitoba.The goal of this collaboration was to develop genetically diverse germplasms of native Canadian grassland species that were well adapted to the Canadian great plains.The germplasm developed for each species was called an ecological variety or ecovarTM, and is best described as pre-variety germplasm.
