DISCOVERY is a high yielding alternative (spring) wheat cultivar bred by Limagrain UK and further developed by PGG Wrightson Grain (PGW Grain) in New Zealand. It is a mid-season, tall awnless wheat with stiff straw and moderate resistance to pre-harvest sprouting. It produces large grain with low screenings, medium test weights and high falling numbers.
For a genuine milling quality wheat, DISCOVERY represents a breakthrough in yield potential and quality across sites and seasons. After 4 years in CPT trials, DISCOVERY has continued to top more trials than any other milling wheat cultivar. It is unrivaled in Canterbury spring trials. In autumn trials DISCOVERY’s 4 year mean yield is higher than any other premium I or II milling wheat. The only milling variety with similar yield potential is Hanson, a gristing wheat.

DISCOVERY is a very high yielding milling wheat. Therefore particular attention to nitrogen management is required to ensure protein milling specifications are met.
DISCOVERY is an alternative or spring wheat cultivar with a wide drilling window. Recommended drilling time is from the middle of May through to September.

DISCOVERY is an intermediate maturing cultivar at harvest.
DISCOVERY has good tillering capacity although it is initially slow to develop. For maximum yield autumn sowing rates should be increased according to the chart below.

DISCOVERY has a good disease resistance profile, being mostly resistant to leaf rust and powdery mildew with intermediate adult plant resistance to stripe rust and Septoria. However it is moderately susceptible to seedling stripe rust. Considering this disease profile, fungicide programmes should be tailored to target seedling stripe rust early on, i.e. Galmano seed treatment followed by a T1 spray, if stripe rust pressure remains high. This approach should protect against Septoria also especially from early plantings.

DISCOVERY is a tall cultivar with good standing power. A robust plant growth regulator (PGR) programme is recommended for this variety especially for early sowings. Spring sowings of DISCOVERY will generally not require as high rates of PGRs. Use of PGRs is generally recommended, with the actual programme determined by a combination of sowing date, seed rate, nitrogen use, crop thickness and yield potential. Please contact your local PGW Representative for site specific recommendations.
