Breeding Insight

GRAHAM is a firm favourite and would be one of the first varieties on my list. With proven on-farm performance and an excellent disease profile which gives that extra flexibility when application timings are compromised, GRAHAM is a difficult variety to beat.

Agronomy Insights

GRAHAM has all the right attributes for early drilling this autumn and has been proven to be a reliable option in the early drilled slot for several years.

GRAHAM has the ideal growth habit for those growers looking to drill early this autumn. The variety has slow over-winter development and a prostrate habit. It is relatively slow to hit stem extension which helps protect the developing ear from late frosts.

Equally important is the agronomic profile. GRAHAM has excellent resistance to primary diseases Yellow rust (8) and Septoria tritici (6.8) which are naturally a higher risk associated with early drilling. GRAHAM also has good straw strength which is critical for early drilling where lodging risk is increased.

Ideal growth habit and stiff straw

  • Prostrate growth habit with good ground cover over winter
  • Slow over winter development
  • Quickly moves through GS30-39, resulting in very early maturity (0)
