Abstract
Napier is a late flowering F6-derived crossbred subterranean clover of var. yanninicum [(Katz. et Morley) Zohary and Heller] developed by the collaborating organisations of the National Annual Pasture Legume Improvement Program. It is a replacement for both Larisa and Meteora and has been selected for release on the basis of its greater herbage and seed production and disease resistance to both known races of clover scorch and 2 of the common races of Phytophthora root rot. Napier is recommended for sowing in Victoria, Western Australia, New South Wales, and South Australia. It is best suited to moderately acidic soils prone to water-logging and to loamy and clay soils with good water-holding capacity in areas with a minimum growing season length of 7.5 months, which extends into late November. Napier is well adapted to the permanent pasture systems found in the areas in which it will be grown. Its upright, vigorous growth makes it well suited to grazing by cattle or sheep and to fodder conservation. Napier has been granted Plant Breeders Rights in Australia.
Acknowledgments
The Grains Research and Development Corporation (GRDC) and Australian Wool Innovation (AWI) provided funding for the selection and evaluation of Napier. The excellent technical assistance of John Titterington, Duncan Wood, Peter Skinner, Michael Davies, Darryl McClements, Jonas Hodgeson, Simon Ambrose, Rosemary Lugg, Bev Roberts, Deborah Ambrose, Neil Cameron, Alan Byron, Trevor Rowe, Craig Rodham, Gabriel Dyce, Brett Wilson and Joshua Taylor in the development of Napier is greatly appreciated. We also wish to thank farmers and Research Station staff for their co-operation.
