Institut für Pflanzenbau und Pflanzenzüchtung Agronomic Properties (previous test results) Advantage stable high alpha acid content high yield potential improved plant health (powdery/downy mildew) good nutrient assimilation capacity cylindrical bine and medium vigor favorable cone/residual plant ratio good hanging of cones from top to the bottom stable high alpha acid rate (1,5-2 % higher than HKS) early and long lasting alpha optimum Disadvantages slow young hop development wilt tolerance weaker than Herkules in extreme years some early flowering may occur Ripeness medium (1 week earlier than Herkules) Harvest good picking and drying Yield high (kg a/ha like Herkules) Agronomic Properties Titan (2011/71/19)
Institut für Pflanzenbau und Pflanzenzüchtung Resistance against Verticillium-Wilt medium Peronospora Primary Infection weak - medium Peronospora Secondary Infection good Powdery Mildew resistant (like MBA) Botrytis good Spider Mite medium Hop Aphid weak - medium Resistance Situation Titan (2011/71/19)
Institut für Pflanzenbau und Pflanzenzüchtung ➢ Good agronomic properties ➢ Good climate tolerance (yield and alpha acid content) ➢ Good aroma evaluation in the expert panel ➢ Positive conclusion of brew trials at three experimental breweries: "high bittering quality like Hercules“ ➢ Large plot trials started in 2020/2021 with five cooperation partners ➢ Processing trial with experimental crop in 2021 (pellet and extract) ➢ Large scale brew trials planned in 2022 and 2023 to achieve release for use in breweries as quickly as possible ➢ Large plot field trials expanded in 2022 ➢ Market launch in 2023, license 30 Cent/kg ➢ Application for plant variety protection was filed in December 2021 ➢ Variety denomination TITAN (TTN) is accepted by the European Plant Variety Office (CPVO) ➢ Planting material is available TITAN (TTN, 2011/71/19): Current Status
