Satellite Symposium 5: Molecular Breeding
Description
Colonial bentgrass species (Agrostis capillaris L.) is a potential genetic resource for the improvement of other bentgrass species (Agrostis spp.) with regard to resistance to environmental stresses and diseases. Transferring resistance from colonial to other bentgrass species is a promising goal in turfgrass breeding programs (Belanger, 2003). Assessment of genetic diversity among accessions of colonial bentgrass species will contribute to eliminate undesirable duplications in the germplasm collection and increase the efficiency of research efforts. It will allow researcher to select diverse resistance genes from different sources to incorporate and pyramid these resistance genes into creeping or other bentgrass species cultivars. The objectives of this study were to investigate the genetic diversity of colonial bentgrass species consisting of 22 PI accessions from USDA collected from 11 countries, 14 accessions from north Spain and three commercial cultivars by using AFLP markers (EcoRI/MseI and PstI/MseI enzyme combinations), and to compare the correlation between estimates of genetic diversity derived from these two enzyme combinations.
