• A consistently high yielding purple wheat from an early to late autumn sowing
• Niche market wheat with appreciably higher value than other wheat types
• Medium to tall cultivar with moderate standing power
As it has a winter habit TYRIAN is best suited to plantings before the end of May, however it has a low vernalisation requirement and can be planted as late as June. TYRIAN typically yields 10-15% over Amethyst. Results from PGW trials indicate that yield advantage and grain quality relative to Amethyst falls off quickly if sowing is delayed past May.

|Kernel weight (1000 seed weight)||47|
|Test weight (kg/hl)||72|
|Protein content (%) (N% x 5.7)||11.8|
|Falling number (sec)||329|
TYRIAN should be given priority at harvest to preserve the colour intensity and to protect falling number.
TYRIAN is slow to develop compared with Amethyst. When planted between May and July TYRIAN will head out approximately one week later than Amethyst. If planted later than this the difference will rapidly widen until the vernalisation requirement is not met and TYRIAN will not head out until it is too late (after mid-December).

TYRIAN is an intermediate to late maturing cultivar at harvest.
TYRIAN tillers very well and this can compromise kernel weights (TGW), so care needs to be taken with plant populations to protect grain quality. Target plant populations should be within the standard PGW Grain wheat guidelines.
TYRIAN has a good general disease resistance profile but is moderately susceptible to Septoria leaf blotch. Considering this disease profile fungicide programmes should be tailored to target Septoria leaf blotch early, especially at T0 and T1 timings. Please contact your local PGW Representative for site specific recommendations.
