Aims

To assess the potential of a range of multi-trait breeders’ lines for commercial development.

Key messages
  • We have identified a small group of material with excellent agronomic performance exceeding our benchmark strand medic cultivars, Herald and Angel, by up to and over 30% for dry matter production and seed yield.
  • The lines are bred from a cross between Angel strand medic and a line originally selected for powdery mildew resistance. They also have SU herbicide tolerance, aphid resistance and larger seed size.
  • If the level of agronomic improvement can be confirmed at regenerating sites, there are good prospects for a future commercial release.
  • Unexpected responses to Rhizobium inoculation confirm some grower observations of poor medic nodulation in the Mallee, but the reasons for this remain unclear.
  • Root lesion nematode number was substantially reduced following a season of medic growth.
