A random sample of 60 germplasm accessions from the Australian white clover germplasm collection was characterized in the field at Glen Innes, N.S.W. Genotypic variation for stolon and other morphological attributes was measured in one season. There were significant differences among accessions, seasons, and accession-by-season interactions for herbage yield. A summer active group, a winter active group and a group showing autumn activity for herbage yield were identified. There was significant variation among accessions for all plant attributes measured and their accession mean repeatability was moderate to high. Five of the morphological attributes expressed a strong genotypic variation estimated for herbage production and plant attributes signifies the potential of the collection to be used as a source of variation for the genetic improvement of productivity and perenniality of white clover for Australian environments.
