KWS Extase

KWS Extase - Group 2 Winter Wheat





GROUP 2 (Milling, ukp Export & Feed)

Boisseau x Solheio

Now firmly established as the UK’s leading winter wheat variety. Consistently high yielding in Agrii trials over the past three years (108%, treated, 95% untreated).

High yields and excellent grain quality
Outstanding Septoria tritici resistance

Variety Positioning

  • A Group 2 bread with ukp for export that has also attracted interest as a feed wheat, due to its high yields, outstanding Septoria resistance and bold grain (79.4 kg/hl).
  • Suitable for all regions of the UK except areas of high sterility risk.
  • Consistent across soil types with good performance on lighter soils.
  • A fast-developing variety best drilled from the last week of September through to the end of December, but it can be drilled to the end of January where necessary.
  • Acceptable second wheat performance and average competitiveness against grassweeds.
  • With tall straw, care is needed particularly on more fertile soils as stem stiffness (7.6) (6.0) could be better and a robust PGR programme should be used.
  • It is early to mature (-1)(-2).
  • Excellent disease resistance with a very strong rating for Septoria tritici (7.8) (7.1), yellow rust (8) (7.5) and brown rust (6.3) (5.2).
  • The juvenile stage of yellow rust may be seen before GS32 and eyespot (3.7) will need attention in a second wheat situation. Not resistant to orange wheat blossom midge.
