LG Defiance

✚ High treated and untreated yields

✚ Good yellow rust and broad disease resistance 

Variety Positioning

• LG Defiance was the second highest yielding hard feed wheat in Agrii’s trials in 2025 (105% treated, 93% untreated), outyield only by KWS Aintree which has much lower yellow rust resistance.  

• It showed similar performance in AHDB trials (109% treated, 95% untreated) with an average specific weight (77.0 kg/hl).

• Its high untreated yields reflect good all-round disease resistance and it is likely to gain significant interest particularly as many other varieties are facing disease resistance breakdown against yellow rust.

• It has shown consistent performance across regions and soil types including lighter land.  It is not suitable for regions of high sterility risk.

• It is best drilled in the main drilling window through to the middle of November.  

• Early indications also support its use as a second wheat although eyespot will require attention. 

  LG Defiance is a tall strawed variety (97 cm -PGR, 87 cm +PGR) with only moderate straw strength (7 treated, 5 untreated) that puts it slightly weaker than Champion.  

• Care is needed on more fertile sites and a robust growth regulator programme is always recommended.  It shows medium maturity (+1 RL, 0 Agrii).

• Good all-round disease resistance profile with mildew (7), yellow rust (8 RL, 8 Agrii), brown rust (5 RL, 5 Agrii), Septoria tritici (6.3 RL, 5.8 Agrii), eyespot (5) and fusarium ear blight (6.6).  It is also resistant to orange wheat blossom midge.
