Comparisons of seven wheat varieties at Eradu locations

To assess the yield and quality attributes and subsequent gross margin returns for 7 commonly grown wheat varieties.

Key messages
  • KING ROCK fell in a hole early, ran up quickly and often looked very heat and moisture stressed.
  • LONGREACH COBRA did not handle a dry year. It did not appear robust or durable in a dry warm season.
  • CORACK and MACE handled drought stress well.
  • CALINGIRI and MAGENTA looked the most durable and robust all year.
  • CALINGIRI again proved very adaptable.
