Clubroot disease is a serious threat to OSR production in Sweden and genetic resistance is the most important factor in a cropping strategy. The aim is to develop a concept for integrated production of winter OSR supported by DNA technology. Infestation levels and yield of resistant and susceptible varieties grown in fields with different infection levels of Plasmodiophora brassicae are investigated. Three resistant varieties of winter OSR are selected together with a mixture of susceptible varieties in six field experiments in fields of low, moderate, high and very high infection levels. Plot-wise DNA analysis of soil are correlated with disease severity and yield. Bioassays are carried out for optimal infection. The presence of virulent isolates breaking reistance of Mendel are identified and determined by classical methods. The potential risk of oil radish as a catch crop is investigated.The goal is to provide an improved support and guidelines for sustainable winter OSR production.
Klumprotsjuka är ett allvarligt hot mot rapsproduktionen i Sverige och genetisk resistens är den viktigaste faktorn i en odlingsstrategi. Målet är att utveckla ett koncept för integrerad produktion av höstraps som stöds av DNA-teknik. Angreppsnivåer och skördeutbyte av resistenta och mottagliga höstrapssorter odlade på fält med olika infektionsnivåer av Plasmodiophora brassicae undersöks. Tre resistenta sorter av höstraps väljs tillsammans med en blandning av mottagliga sorter i sex fältförsök på fält med låg, måttlig, hög och mycket hög infektionsnivå. Rutvis DNA- analys av jord korreleras med angrepp och avkastning. Biotest utförs samtidigt i växthus för optimal infektion. Förekomst av virulenta isolat som bryter reistensen hos sorten Mendel identifieras och bestäms med klassiska metoder. Den potentiella risken med oljerättika som fånggröda utreds. Målet är att tillhandahålla ett förbättrat stöd och riktlinjer för en hållbar höstrapsproduktion inom områden där P. brassicae finns.

Wheat bran is the largest by-product of wheat flour production with approximately 300,000 tonnes in Sweden. Bran is mainly used in animal feed, as human digestion is not fully able to absorb it. Wheat bran contains valuable biomolecules, such as dietary fiber (arabinoxylans, AX) and phenolic …

Competing unshod is an important issue for the Swedish harness industry. There is a general opinion that performance may increase significantly but it does not always work. The reason for failure may be disturbed locomotion “balance” of the horse or due to pain from the hooves. This is obviously …

The purpose of this project is to define the amount of slaked lime needed for a given clay soil. We hypothesise that the amount of slaked lime needed for minimal phophorus loss is dependent on the clay content of the soil. The study will be conducted in a field with a drainage system and measuring …

Acquired equine polyneuropathy (AEP) is a devastating neurologic disease affecting Nordic horses. Characteristic histopathological changes have been shown in the peripheral nerves of horses euthanized due to the disease. These include re- and demyelination as well as hypertrophy of perikaria and …

Resistance to anthelmintic drugs is a threat to equine welfare. Like antibiotics, is restrictive use of anthelmintics necessary to retain their effectivity. Thus, targeted selective treatment, based on individual deworming, was introduced a decade ago. However, we have shown that the prevalence of, …

Increased production and export of products with high added values, e.g. long-ripened hard cheeses, are considered important steps for a positive development of the Swedish dairy sector. Increased investment in Swedish premium cheese will, however, require increased volumes of high quality raw milk …

The aim of this project is to investigate individual differences in the rate of passage of feed, feed efficiency, microbial flora and methane production in cows with different ability to consume large proportion of roughage.
Our previous studies show that methane production differs between cows …

Knowledge of disease development in wheat is a prerequisite for good advice on economically and environmentally
adapted control strategies. This project is based on knowledge from a previous SLF project about molecular detection
and spore traps, which showed that the different spore traps catch …
