BreedingValue - Marker-Assisted Selection (MAS) and Genome wide association studies (GWAS) in Raspberry

Marker assisted selection is a method used to select desirable individuals in a breeding programme based on DNA molecular marker patterns in addition to their trait values. This can serve as a valuable tool to assist breeders to select more efficiently. In this BreedingValue project, we will identify molecular markers which can be useful to breeders across all raspberry breeding programmes for traits such as fruit size, softening, timings of fruit development stages, cane diseases or fungal diseases such as yellow rust.

The objective of the Open Call#3 is to offer breeders an opportunity to screen and select their genotypes of interest against a suite of markers, which can help breeders to better select parental material depending on the trait of interest. Genome wide association studies (GWAS) delves further into the genetic variants within screened markers across different individuals to determine if any of these variants are associated with a particular trait or disease such as yellow rust susceptibility.

In this Open Call, we will fund 2 projects à 20,000€.

Who are we looking for?

We are looking for breeders with robust phenotypic information (or with the ability to obtain such within the call’s time frame) on a diverse range of around 450 raspberry material. The breeder must also be able to provide extracted DNA or leaf material for genotyping and have little or no experience with MAS and GWAS with an interest in developing this approach further.

Application Deadline: 30 June 2021 17:00 (CET time)

BreedingValue - Genomic selection for Strawberry

Genomic selection is used to select breeding material for further hybridization and/or for entering advanced cultivar trials based on their genomic breeding values rather than on phenotypic values. This approach shows better performance than traditional methods such as phenotype-based selection, pedigree-based selection, and marker assisted selection, particularly for polygenically inherited traits.

The objective of this Open Call

The objective of the BreedingValue Open Call #2 is to employ state-of-the-art methodology on breeders’ material and implement genomic selection to the breeders. This can help the breeders to do selection in early stages of their breeding program, accelerating the generation cycles by identifying superior parents, and increasing likelihood of identifying good candidates for advanced trialing.

In the Open Call#2, we will fund 2 projects à 20,000 €.

Who are we looking for?

We are looking for applied strawberry breeders with phenotype data available (or with ability to obtain such within the call’s time frame) for a high number of cultivars and/or breeding lines of strawberry (F. ×ananassa). The breeder must also be able to provide extracted DNA and have an interest to develop and apply genomic selection on own breeding material.
