Abstract

Cynodon L. C. Rich comprises warm season grass species that are valuable as turf and forage in warm climates across the globe. Traditionally, Cynodon breeding programs have aimed to produce varieties with improved turf and forage grass quality characteristics. More recent goals, such as improved abiotic stress tolerance, aim to address challenges associated with climate change. Germplasm collections representing a fraction of the global distribution of Cynodon comprise the plant resource for these breeding programs. We compared a core collection consisting of 116 Australian genotypes with an international core collection of 59 genotypes representing Cynodon’s global distribution. Our aims were to determine whether unique genetic diversity exists amongst Australian Cynodon that may enhance international breeding resources. This research will facilitate the incorporation of Australian Cynodon genetic resources, which have expanded and naturalized under harsh Australian climates, into existing germplasm collections.
