Research Project: CucCAP 2: Harnessing Genomic Resources For Disease Resistance And Management In Cucurbit Crops – Bringing The Tools To The Field

Location: Crop Improvement and Protection Research

Project Number: 2038-21530-003-001-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Sep 1, 2020
End Date: Aug 31, 2025

The objectives of this project are to: (a) develop shared genomic approaches and tools for cucurbit species (cucumber, melon and watermelon); (b) identify and map resistances to key diseases and conduct comparative genomic analyses to identify syntenic regions among the cucurbit species; (c) develop breeding tool kits for accelerated crop improvement and initiate introgression of resistance into elite cultivars.

Develop appropriate genetic populations for each key disease, conduct phenotypic assays using greenhouse and field tests, and genotypic analyses using genotype by sequencing in order to construct genetic maps; associate phenotype and genotype data for quantitative trait loci (QTL) identification and gene mapping; and identify molecular markers for efficient trait selection and gene pyramiding. GBS will be performed on core populations for each crop species to provide a standing resource for genome wide association studies (GWAS).
