Novel Festuca arundinacea Shreb. and Dactylis glomerata L. germplasm to improve adaptation for marginal environments

Abstract

Tall fescue (Festuca arundinacea Schreb., Lolium arundinceum Schreb., S.J. Darbyshire) and cocksfoot (Dactylis glomerata L.) were identified for improvement for low to medium rainfall (400-700 mm) environments where persistence of common cultivars has been unreliable. Over 200 accessions and experimental varieties of tall fescue and cocksfoot sourced from the Mediterranean basin were screened over 2 years at sites on the North-West Slopes of NSW and on the Central Highlands of Victoria, respectively. These were compared with some locally naturalised plants and most of the cultivars available in Australasia as well as cultivars developed for warm temperate and Mediterranean climates in Italy,..
