This article presents the spring wheat breeding program at the Swiss federal research station of Changins and its results in Switzerland and in the world. Since the first Swiss crosses in 1947, the selection of spring wheat aims to obtain varieties of excellent baking quality (classes I or TOP) and very good disease resistance. Today, cv. GREINA (class I) is the most cultivated in Switzerland. The variety FIORINA combines a very good baking quality (Class TOP) to a very high yield and good cold resistance. The analysis of the glutenins in Swiss lines and varieties revealed rare alleles, which have a positive role for baking quality. They will be used in future crosses.

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.
