Calibre

Calibre is the first variety derived from Scepter to hit the market, offering very high grain yields across WA.

Calibre 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. Magenta 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 Magenta but with much improved yield.

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

With very high 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 spot resistance of Calibre is good, achieving a very similar level of resistance to Scepter. Calibre also offers a valuable improvement in stem rust and powdery mildew resistance over Scepter and Vixen.
