PROTECTOR PT303 is the first winter oilseed rape hybrid to offer growers in the UK and Ireland top level yields with built-in tolerance to Sclerotinia. • Gross Output of 101% on 2024 AHDB UK Recommended List • Sclerotinia tolerance • Good resistance, or tolerance, to Verticillium stem stripe • Turnip yellows virus (TuYV) resistance • Strong autumn vigour and spring regrowth • Light Leaf Spot 7, Stem Canker 6 • Specific Rlm7 phoma resistance plus broad genetic resistance • Unique growth habit and genetics spreads risk from damaging late season stem-based disease • Later flowering - earlier...

Top level gross output Sclerotinia tolerance PT303 has an impressive UK gross output yield on the AHDB Recommended List of 101%. This high gross output is derived from a very high seed yield and a top-level oil content.. PT303 is the first hybrid to be marketed in the UK with a claim for tolerance to Sclerotinia. This yield sapping disease can reduce yields in commercial situations by up to 30%. Gross output and oil content of PT303 versus selected varieties AHDB UK recommended list 2024 112.0 Groos Output (%) Significant yield loss can occur where flowering fungicide applications are...

Sclerotinia infection is largely eliminated from both treated and untreated AHDB trials through comprehensive fungicide applications at flowering. In commercial situations however flowering treatment programmes may be more limited, and applications may be inadvertently mistimed. PT303 has given very high gross output yields in AHDB UK RL trials even though sclerotinia infection was probably well controlled at all locations. The Sclerotinia tolerance of PT303 is therefore likely to be an additional benefit to its proven performance. Consider that results from trials that are comprehensively...

Impact of incidence of sclerotinia infection, 2019-2021 Severity of sclerotinia impact, 2019-2021 Fungicide reference Incidence = frequency of stems infected by Sclerotinia sclerotiorum. Sclerotinia Protector significantly reduced the number of infected stems. Average reduction of 36%. The variability of infestation of PT303 was significantly less than the check. Fungicide reference Fungicide reference Severity = intensity (extent) of Sclerotinia lesions. Sclerotinia Protector significantly lowered the severity on plant stems. Average reduction of 42%. The reduction of the variability of...

ADAS trials at a UK location with a recent history of verticillium have indicated PT303 has partial resistance or tolerance to Verticillium Stem Stripe. Combined with its tolerance to Sclerotinia, this gives PT303 a unique potential to reduce the severity of yield robbing stem-based disease at harvest. ADAS results at this location confirmed the ability of PT303 to quickly establish high levels of ground cover and grow rapidly in both the autumn and spring, even in a verticillium infected site. Verticillium stem stripe pre-harvest assessment Verticillium Verticillium Premature incidence...

Stem health Light leaf spot and stem canker PT303 stem health at maturity reduces premature senescence and its damaging effect on yield. PT303 has broad agronomic strengths. It provides a resistance score of 7 light leaf spot and 6 for stem canker. Its good base disease resistance package makes it suited to any location. Leading competitor Phoma resistance is derived from both Rlm 7 and broad-based genetic sources ensuring it is appropriate for high pressure situations. Turnip yellows virus (TuYV) resistance PT303 has TuYV resistance as confirmed by GEVES testing in France.

PT312 provides a very high gross output yield with a very high oil content combined with turnip yellows virus resistance and Sclerotinia tolerance. • Gross Output of 109% in NIAB Trials • Very high oil content of 47.6% in National List Trials • Turnip Yellows Virus (TuYV) resistance • Sclerotinia tolerance • Stem Canker 7, Light Leaf Spot 5 • Large stature hybrid that has scored 9 for lodging and 8 for stem stiffness

PT312 has given a very high gross output yield of 109% in NIAB trials. This top-level yield performance comes with a unique agronomic package including turnip yellows virus resistance and sclerotinia tolerance. PT312 scores 7 for stem canker resistance and 5 for light leaf spot PT312 gave the highest oil content of any variety in 202022 UK National List Trials. This level of oil content is likely to generate significant oil bonus payments. An illustration of the type of oil bonus payments that may be achieved can be seen in the table below.

PT315 has given a high gross output yield with a very high oil content. It combines pod shatter resistance with turnip yellows virus resistance. • High Gross Output of 106% • Very High oil content of 46.8% • Turnip yellows virus (TuYV) resistance • High rating of 6.9 for early autumn vigour • Light Leaf Spot 6, Stem Canker 6 • Phoma resistance based on RlmE and horizontal quantitative genetic resistance • Large stature hybrid that has scored 9 for lodging and 8 for stem stiffness
