Research Project: Qtl Mapping of Fruit Size in Cucumber

Location: Vegetable Crops Research Unit

Project Number: 3655-21000-062-09
Project Type: General Cooperative Agreement

Start Date: Aug 09, 2011
End Date: Jun 30, 2013

1. Develop and characterize cucumber and melon populations segregating for fruit size. A set of segregating populations from cucumber will be analyzed for fruit size phenotype. 2. Combine genomic tools, segregating populations, and phenotypic characterization to identify loci associated with fruit size. Genetic analysis using the SNP arrays developed in this project and segregating populations for fruit size will identify QTL associated with fruit size.

Three mapping populations will be used for phenotyping of fruit size (RIL and F2:3 families). Phenotypic data will be collected from field trials in three years (2011, 2012, and 2013) at both greenhouse and field conditions. Whole genome scan of different population segregating for fruit size will be conducted for QTL analysis to establish marker-fruit size trait associations.
