Graham

✚ High yields and good physical grain quality

✚ Wide drilling window and stiff straw

Variety Positioning

• Graham remains one of Agrii’s biggest selling hard feed wheats, and while its disease resistance is not what it once was, it continues to perform consistently well on-farm and in trials (RL 102% treated, 86% untreated; Agrii, 102% treated, 72% untreated) and it produces a nice bold grain (77.6 kg/hl).  

• More suited for East and West regions with yield performance falling away in the North.

• It can be grown on heavy and lighter soil types, but it should always be grown as a first wheat as its second wheat performance is relatively poor.

• Graham can be sown across the drilling window. It has a relatively slow speed of development in the autumn and is ideal for early drilling, yet it moves relatively quickly in the spring.

• It has a very prostrate autumn growth habit with medium to high tillering capacity so seed rates can be reduced.

• Agrii late sowing trials show that it continues to yield well through to the end of January. Average competitiveness against grassweeds.

• Average straw height and decently stiff straw, treated (RL 8; Agrii 7) and untreated (RL 7; Agrii 6).  Early to mature (-1).

• Disease ratings remain good for mildew (RL 6; Agrii 7) but both Septoria tritici (RL 6; Agrii 6) and yellow rust resistance (RL 8; Agrii 5) have started to decline.  

• Brown rust has always been weak (RL 5; Agrii 3) together with eyespot (4) and stem-base diseases.

• Not resistant to orange blossom midge.
