All the listed projects below are available at the Department of Plant Breeding at SLU in Alnarp. In some cases, it can be flexible regarding the degree level of the projects. Welcome to contact the contact persons listed to each specific project to learn more and to discuss a possible time plan.

Evaluation of genetic markers for convicine and vicine content in a diversity panel of faba bean

Faba bean is a protein crop that is used mostly for animal feed in Sweden today, but increased cultivation and use in food will probably be seen in the future. Convicine and vicine are undesired compounds in faba bean seeds. In this project, which will be based on lab work and bioinformatics analyses, available DNA markers for low convicin/vicine content will be evaluated in a diversity panel of faba bean accessions using PCR and DNA-sequencing.

Food and feed protein from green leaves – Increasing the protein recovery rates

Green leaves, e.g., in the form of sugar beet leaves or lucerne, can be a source of protein for both humans and non-ruminant animals. But first the proteins need to be extracted. Our process method start with pressing juice from the leaves, resulting in a green juice containing most of the protein, and a fibrous pulp. However, the recovery rates low, as much of the protein remains in the pulp. In this project, we investigate different methods for increasing the protein recovery, and you would be part of this development.

Investigation on long day light regime influence on the oil crop turnip rape cultivated in North Sweden

Cultivation of crops in North Sweden faces a major challenge in the short field season, which limits the number of crops that can be grown and reach full maturity. One way to possibly compensate for the short field season could be to identify, through plant breeding, crop varieties that have the ability to take advantage of the greater number of sun hours (long days) during June and July when northern Sweden basically has continuous light. Such varieties can then conceivably develop faster and reach maturity within the shorter field season available. When breeding for better variants of the oilcrop turnip rape (Brassica rapa spp olifera) for cultivation in North Sweden, beside improving its winter hardiness it is also important to take into consideration its ability to respond positively to the long-day light conditions.

This project will use accessions of turnip rape identified to respond positively to constant light (mimic long day conditions in the North). These accessions will be grown in the Biotron under normal day/night light conditions and constant light respectively. Different phenotypic traits of the plant material will be recorded at specific time points as a measure of the different accession. Plant material from the different accessions and in the different light treatments will be sampled and analysed for gene expression (trancriptome analysis). Phenotypic and genotypic data will be analysed for markers (SNP) linked to a positive response to the long day condition.
