Potato cultivars that are resistant to late blight and at the same time having acceptable other traits, have started to emerge. However, little of this material is used in Sweden and no organized and comparative table potato trials are done. Biological products against skin-finish diseases are becoming available, and skin-finish as well as drought cause increasing problems for Swedish potato growers. The main goal of this application is to promote the use of resistant cultivars and biopesticides in potato production in Sweden. This will be achieved by screening-trials with a large start material, followed by comparative trials at three different regions with different cultivation systems: conventional, biopesticides and ecological. Traits such as resistance to late blight, drought and skin-finish, as well as yield and size distribution will be analyzed. New types of molecular analyses and communication will also be carried out to ensure diversity of resistance mechanisms.
Nya potatissorter har börjat bli tillgängliga som är resistenta mot bladmögel samtidigt som de verkar acceptabla ur andra synpunkter. Bara lite av detta material används i svensk potatisproduktion och inga officiella sortförsök görs med matpotatis. Nya biologiska produkter mot skalfinish problem utvecklas, och skalfinish samt torka är ökande problem för svenska potatisodlare. Syftet med denna ansökan är att främja hållbar användning av nya resistenta potatissorter och biopesticider i svensk potatisproduktion. Detta kan nås genom screeningförsök av omfattande startmaterial samt jämförande fältförsök i tre regioner med olika odlingssystem: konventionellt, biopesticider och ekologiskt. Egenskaper som resistens mot bladmögel, torka och skalfinish samt utbyte och storleksfördelning undersöks. Nya typer av molekylära analyser kommer också att utföras för att gynna en mångfald av resistensmekanismer. Information kommer att kommuniceras för att främja hållbart sortval och sortutveckling.

All horses grazing freely are at risk of parasitic diseases. Due to a growing problem with drug resistance in parasites, there is a need to improve the diagnostic methods. One important problem with today's situation is that one diagnostic procedure costs significantly more than one treatment, both …
