2012 - Washington Red Raspberry Commission

learn will be useful for the project “Roadmap Development for U.S. Raspberry Producers:
Forging Links Between New Tools for Breeding Programs and Crop Markets” that was
successfully submitted as a planning grant and the full project that they will submit one year from
now.
Relationship to WRRC Research priority(s):
Our objectives for raspberry breeding most closely align with a #1 Commission Priority
as we are trying to develop cultivars “that are summer bearing high-yielding, winter hardy,
machine harvestable, disease and virus resistant and have superior processed fruit quality. The
traits we identify and the tools we develop will be useful in developing improved red raspberry
cultivars.
Objectives:
The overall goal of this proposal is to develop and make available genomic tools for the
improvement of black and red raspberry (Rubus occidentalis, and R. idaeus, respectively,
subgenus Idaeobatus) and begin the application of these tools in using wild black raspberry
germplasm for crop improvement. Specifically:
1) Transcriptome sequencing and high throughput genomic sequencing.
2) Developing molecular markers from genomic and EST sequences.
3) Studying genotype by environment interaction on specific traits of interest in crosses
involving diverse wild black raspberry germplasm.
4) Using molecular markers for mapping specific traits of interest in crosses involving diverse
wild black raspberry germplasm.
5) Evaluate transferability of SSR markers developed in black raspberry to red raspberry.
6) Better understanding of consumer preferences for market expansion.
7) Delivering research results and training in molecular breeding to the industry, breeders, and
students through a multifaceted outreach program.
