For a long time, the research station Agroscope Changins-Wädenswil ACW has been breeding new apple varieties. High quality varieties are developed which are resistant and tolerant to diseases and which need a minimum of plant protection. Two new selections, ACW 6375 and ACW 11907, are candidates for being introduced on the market. Therefore, two consumer tests were performed, one in the German-speaking part of Switzerland and one in the French-speaking part, in order to investigate how these varieties are evaluated visually and sensorially by the consumers. In addition, sociodemographic data, frequency of fruit consumption and flavor-preferences were examined. Results show that the new selections are comparable to established cultivars. Similar flavor preferences in both regions are illustrated. The flavor of the fruit is the attribute that mostly affects the overall sensory judgement. Once again, the importance of the ripeness of an apple is highlighted. Flavorless and floury apples are rejected by customers.

The root knot nematode (RKN) Meloidogyne incognita causes damage in field and greenhouse crops. Agroscope researchers have developed a new screening test to identify bacteria that antagonise this agricultural pest.
With CULTAN fertilisation, nitrogen is injected into the soil as an ammonium solution. Multi-year trials conducted by Agroscope show that this method reduces nitrogen leaching by an average 38% without negatively affecting yields.
Tuta absoluta is one of the most destructive pests of solanaceous crops. Agroscope has developed a statistical model to study the population dynamics of the pest and its parasitoids and allows interventions to be optimally planned.
