Research Project: Cranberry Phenotyping and Mapping Cranberry Quality Traits

Location: Vegetable Crops Research

Project Number: 5090-21220-004-007-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2018
End Date: Dec 30, 2022

1) Phenotype and map cranberry quality traits to include fruit firmness, size, shape, color, and several chemical traits. 2) Understanding the physiological and molecular basis of processes that underlie water relations, soil nutrient dynamics, and plant uptake during cranberry production.

Use three to five existing biparental populations in cranberry to phenotype and map genes controlling important quality traits required by the industry to process sweetened and dried cranberries (SDC). The traits to be analyzed will include fruit firmness, size, shape, color, and several chemicals traits to include anthocyanins, proanthocyanidins, acids, and brix. Use existing molecular maps for three populations and will build two more molecular maps for mutant populations segregating for fruit color, size, and shape. Genome sequence will be completed and will serve to integrate sequencing and mapping efforts while providing support for marker data and marker-trait associations and to search for candidate genes.
