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 104% on AHDB UK Recommended List • Sclerotinia tolerance • Verticilium stem stripe tolerance • Turnip yellows virus (TuYV) resistance • Strong autumn vigour and spring regrowth • Light Leaf Spot 7, Stem Canker 6 • Phoma resistance from Rlm7 and horizontal quantitative genetic resistance • Unique growth habit and genetics spreads risk from damaging late season stalk-based disease • Later flowering - earlier maturing...

A top gross output PT303 has an impressive UK gross output yield on the AHDB Recommended List of 104%. This high gross output is derived from a very high seed yield and the highest oil content of any AHDB UK listed variety. Gross output and oil content of PT303 versus selected varieties AhDB UK recommended list 2023 Sclerotinia tolerance 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%. 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. Consider that results from trials that are comprehensively treated for disease at flowering time may entirely mask Non-tolerant comparator susceptibility to stalk diseases such as sclerotinia and verticilium stem stripe. PT303 has given very high gross output yields in AHDB UK RL trials even though sclerotinia...

Fungicide Untreated Fungicide Untreated Fungicide Untreated 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. 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 lesions was very marked, even in untreated plots. The efficacy of the fungicide treatments applied...

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

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 for both light leaf spot and stem canker and its base disease resistance package makes it suited to any location. Leading competitor Phoma resistance is derived from both Rlm 7 and horizontal quantitative sources ensuring it is appropriate for high pressure situations. Turnip yellows virus (TuYV) resistance PT303 has TuYV resistance confirmed by GEVES in France.

With a high oil content and stiff straw, PT279CL has provided growers with high harvestable yields since first being listed on the AHDB Recommended List. Gross output and oil content of PT279CL versus other Clearfield hybrids Gross Output (%) The first Clearfield hybrid to be added to the AHDB Recommended List. PT279CL has maintained its position on the East/West Recommended List and is a commercially proven Clearfield type. Gross Output (%)

PT315 is a new Pioneer hybrid for 2023. 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% • Pod shatter resistance • 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

Top Level Gross Output and Agronomic PT315 has given a very high gross output yield of 106% of the Control yield with a very high oil content of 46.8%. This top-level yield performance comes with a unique agronomic package including pod shatter resistance, turnip yellows virus resistance and the highest autumn vigour score of any hybrid in the Pioneer range.
