Satellite Symposium 5: Molecular Breeding
Description
The crested wheatgrasses (Agropyron spp.) are widely distributed Eurasian grasses that have been used to re-vegetate millions of hectares of land in the northern plains and intermountain areas of North America. The genus consists of about 10 species that are based on the ‘P’ genome and includes diploids (2n = 14), tetraploids (2n = 28) and octoploids (2n = 42) (Dewey, 1984, Vogel et al., 1999). The two main agronomic species used in North America are A. cristatum (L.) Gaertner and A. desertorum (Fischer ex Link) Schultes. Chloroplast genomes are predominately maternally inherited through the cytoplasm in angiosperms. Chloroplast DNA (cpDNA) variation can provide information on the evolutionary development of plant species. The objective of this study was to determine if chloroplast DNA polymorphisms occur within and among ploidy levels of these two main species of the Agropyron complex.
