Research Project: Quality Evaluation of Berry Selections and Varieties

Location: Horticultural Crops Research

2013 Annual Report


1a.Objectives (from AD-416):
1. Evaluate advanced breeding selection from SYs breeding program (USDA/ARS/NCSFR) and variety trials for objective attributes related to processing or fresh market potential. 2. Process samples of advanced selections, selected field crosses, and standard varieties for display to and evaluation by breeders and the industry. 3. Include blueberries, black raspberries, and other berries grown around the region along with strawberries, blackberries, and raspberries as has been done in the past. 4. Prepare summary of all data in report format for use by breeders and industry members.


1b.Approach (from AD-416):
Berries for this project will come mainly from plots at the North Willamette Research and Extension Center but may also come from other research fields in Corvallis or Washington or from grower fields. Selections and cultivars will be sampled throughout their harvest periods to track variations in fruit quality over time. New selections will be processed and analyzed from one to three times. Advanced selections will be sampled weekly.


3.Progress Report:

This research was conducted in support of NP301 objective 1A of the parent project. Berries from the breeding plots at the North Willamette Research and Extension Center were picked weekly and brought to the Oregon State University (OSU) Food Science Department in Corvallis, Oregon, for processing and evaluation from mid June through mid September. Basic chemical data were collected on strawberries, red raspberries, black raspberries, blackberries, and blueberries for multiple harvest dates throughout this period. Samples were frozen and displayed to industry representatives and researchers during the fall, winter and early spring. This information will be used with field data to select the berries which will be included in further breeding trials.

During the 2012/13 season the following numbers of samples were processed and analyzed: Strawberries – 13 cultivars, 33 ORUS selections, 3 samples sugared and sliced Red raspberries – 10 cultivars, 29 ORUS selections, 10 WSU selections Blackberries – 3 cultivars, 45 ORUS selections Black raspberries – 2 cultivars, 32 ORUS selections Blueberries – 5 cultivars, 44 ORUS selections, 6 ARS selections, 11 MSU selections Many of these cultivars and selections were sampled and processed on multiple harvest dates.

Processed fruit was displayed for evaluation on nine occasions during the past year: Research evaluation of all samples for breeders, researchers, and industry at OSU during December (2 days) Northwest Food Processors Association annual meeting in Portland, Oregon, Oregon Strawberry Commission annual meeting at the OSU North Willamette Research and Extension Center Oregon Raspberry and Blackberry Commission annual meeting in Woodburn Oregon Raspberry and Blackberry Commission spring workshop Oregon Blueberry Commission annual meeting in Portland, Oregon North American Strawberry Growers/North American Raspberry and Blackberry Growers national meeting in Portland, Oregon OSU Strawberry Field Day at the OSU North Willamette Research and Extension Center OSU Caneberry Field Day at the OSU North Willamette Research and Extension Center OSU Blueberry Field Day at the OSU North Willamette Research and Extension Center
