Proceedings of Northwest Center for Small Fruits Research.Interpretive Summary: This is our first year progress report for a NCSFR funded proposal on our findings to assess fruit quality characteristics related to processing in the 750+ strawberry genotypes.
                                Technical Abstract: In an effort to implement marker-assisted breeding in Rosaceae, many traits need to be characterized in diverse germplasm. The USDA-NIFA Specialty Crop Research Initiative-funded RosBREED project includes breeding programs of four Rosaceae crops (apple, peach, cherry, and strawberry). Phenotyping each crop for specific horticultural and commercial traits is an important process needed to translate genomic knowledge through marker-assisted breeding into enhanced breeding efficiency. This data will directly aid in the identification of quantitative trait loci or marker-trait associations that will be used to assist breeding programs in the future. Large-scale, standardized phenotyping protocols have been set up for each crop. The standardized phenotyping protocol for strawberries was agreed upon by the breeding teams in Oregon, Michigan, New Hampshire, California, and Florida and includes four trait categories: phenology and other flower-related traits, plant characteristics, fruit characteristics, and fruit chemistry traits. This USDA-ARS, NCSFR grant allowed us to determine the fruit chemistry analysis (pH, percent soluble solids, titratable acidity, total anthocyanins, and total phenolics) and drip loss of frozen-thawed fruit. The protocol has been determined and all of the samples evaluated. The data is being analyzed. A summary of mean values for 37 traits of the genotypes planted at the RosBREED locations in 2011 and 2012 is available through the “Breeders Toolbox” at the Genome Database for Rosaceae (http://www.rosaceae.org/breeders_toolbox).
