Expert X Premio

✚ Very high yields and good physical grain quality
✚ Wide drilling window and good resistance against Septoria tritici.

 

Variety Positioning

  • Graham certainly can yield and has done so in the Agrii national
    trials over the last eight years, where it has been consistently in the top five.
  • Its high treated yields (105% treated, 93% untreated) can be attributed to its good disease resistance and bold grain (77.6 kg/hl).
  • More suited for East and West regions with yield tailing off in the
    North and best not grown in Scotland or other areas of high sterility risk.
  • 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 multi-task 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-drill trials show that it continues to yield well through to the end of January.
  • Average competitiveness against grassweeds. Has average straw
    length and decently stiff straw, treated (7.6) (7) and untreated (6.6) (6). Early to mature (-1).
  • Apart from a lower eyespot score (4), other disease ratings are generally good with mildew (6), yellow rust (7.8) (6.5) and Septoria tritici (6.7) (6.7), but watch brown rust (4.7) (3.9).
  • Not resistant to orange blossom midge.
