Breeders comments

Calibre is the first vartiety derived from Scepter to hit the market, offering a number of important improvements over its parent.

Calibre has an APH quality classification in southern NSW. This is an improvement over both its parent Scepter and other AH main season benchmark Beckom, allowing growers of Calibre to capitalise on high protein levels when the opportunity arises.

Calibre also offers growers the opportunity to access longer coleoptile genetics in an elite yielding background. The coleoptile 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. Calibre has a longer coleoptile which may offer benefits to growers in these situations.

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

The yellow leaf spot resistance of Calibre is good, achieving a similar level of resistance to Scepter. Calibre also offers a valuable improvement in powdery mildew resistance over Scepter.

With elite grain yield, improved coleoptile length, APH quality, very wide adaptation, and a disease resistance package similar to its parent Scepter, Calibre makes an excellent replacement for Scepter.
