Australian breeding and improved persistence with Warrego GT6, the upgraded replacement to Stamina® GT6

Trialled and tested in multiple environments and conditions, Warrego GT6 is a significant step up in grazing tolerance and persistence compared to older dormancy 6 varieties. Bred to persist for prolonged periods of set stocking, Warrego GT6 provides growers with grazing flexibility, high quality hay, persistence similar to a dormancy 5 and, the winter activity of a 6. Warrego GT6 is a new generation, highly persistent, true grazing tolerant lucerne. Warrego GT6 was selected and bred from grazing tolerance trials in Leigh Creek (VIC) and Gundagai (NSW) and trialled under the internationally recognised Standard Test Protocol for grazing tolerant lucernes.

Sowing rate (sole): 5-25kg/ha
Sowing rate (mixed): 2-8kg/ha

Warrego GT6 (of the Stamina® range): Lucerne trial analysis

  • Warrego GT6 ground cover was 75% when measured after the first set stocking period in 2014, which means Warrego GT6 displays similar ground cover to dormancy 5 varieties
  • After another six months set stocking period in 2015, Warrego GT6 maintained a ground cover percentage of 75%, while other dormancy 6 varieties continued to decline
  • After 2 consecutive set stocking periods in 2014/2015, Warrego GT6 had 60% more ground cover in comparison to Aurora

In comparison to older cultivars, such as Aurora, and after all cultivars were trialled under the internationally recognised Standard Test Protocol for grazing tolerant lucerne, it was evident that:

  • when measured after the first set stocking period in 2014 Aurora (a non GT lucerne) dropped to 25% in ground cover, rendering the stand unviable.
  • Aurora continued to decline in 2015, dropping to 15% ground cover.
  • with increased persistence, Warrego GT6 gives growers management flexibility, allowing them to decide when to terminate the stand in comparison to Aurora.

 

Dormancy

Winter active (6-7): Tend to have smaller crowns with an erect growth that provides some winter growth (providing suitable temperatures). Although a multi purpose stand that provides quality hay production and grazing opportunities, strict rotational grazing management is required as winter active (6-7) lucerne varieties are comparatively less tolerant to grazing than semi winter dormant (5) varieties.
