Calibre

Calibre is the first variety derived from Scepter to hit the market and is the next step for growers looking to achieve the gains they made by switching from Mace to Scepter.

Not only is Calibre the next step in grain yield, it also offers growers the opportunity to access longer coleoptile genetics in an elite yielding background. The coleoptile length of a wheat variety is a factor that limits how deep you can plant. So, it’s not surprising that there are many instances where a longer coleoptile is needed: when there is a chance of furrow fill by wind or rain; when chasing receding moisture profiles; or when trying to achieve adequate pre-emergent herbicide separation. Yitpi is a good example of a variety with a longer coleoptile that has been used in the past by growers to manage such situations but is now outclassed. Calibre has a similar coleoptile length to Yitpi but with elite yield performance.

Calibre is slightly taller than Scepter, so growers may observe some leaning or lodging when Calibre is grown in higher yielding situations.

With elite grain yield, improved coleoptile length, AH quality, very wide adaptation, and a disease resistance package similar to its parent Scepter, Calibre makes an excellent replacement for Scepter. The yellow leaf spot resistance of Calibre is good, achieving a very similar level of resistance to Scepter. Calibre also offers an improvement in powdery mildew resistance over Scepter. In comparison to Vixen, Calibre offers higher grain yields in low-medium yielding environments, a longer coleoptile, much better sprouting tolerance, a slower maturity and higher levels of CCN resistance. Calibre will also be compared to Ballista. Both varieties are similar in many respects but with Calibre offering a longer coleoptile; and better yellow leaf spot, septoria tritici and powdery mildew resistance.
