Objectives:

1. To improve meat and dairy production by breeding improved cultivars of perennial ryegrass that are adapted to target areas of Australia;

2. To produce cultivar/s which have: - improved winter growth (Project 1) - improved autumn growth and drought tolerance (Project 2) - improved seasonal growth and late season growth (Project 3);

3. To conserve the genetic diversity of grass and legume species from north Africa suitable for pasture development in Australia;

4. To bulk up and incorporate north African acquisitions into existing improvement and evaluation programs.

Methodology: This project deals specifically with the national evaluation of breeding lines developed from an improvement project (DAV 94 jointly funded with the Meat Research Corporation) and the collection of pasture species from north Africa. There are six recognised climatic regions where perennial ryegrass is used. The evaluation project has, through a network of collaborators within Australia and New Zealand, established trial sites in each region to test breeding lines.

Progress: The evaluation of breeding families has, through a network of collaborators within Australia and New Zealand, established evaluation sites in each region to test breeding families. Nine trials have been established in Victoria, New South Wales, South Australia, Tasmania, Western Australia and New Zealand to evaluate material developed within earlier projects. The international genetic resource collection mission to north Africa (8 July-13 August 1994) was completed. Collections of target species were completed at 188 sites in Sardinia, Tunisia and Morocco to give a total collection of 472 accessions.

Period: starting date 1990-07; completion date 1998-06

Status: Completed.
