Research Project: Identifying Genetic Sources of Virus And Vector Resistance in Cucumis Melo for New Cultivar Development

Location: Crop Improvement and Protection Research

Project Number: 2038-21530-002-21-R
Project Type: Reimbursable Cooperative Agreement

Start Date: Nov 1, 2018
End Date: Apr 30, 2021

Objective:
Characterize mechanisms of resistance to sweetpotato whitefly (SWF) in four melon accessions that are either resistant or susceptible to Cucurbit yellow stunting disorder virus (CYSDV), determine the genetic control of resistances to SWF and CYSDV and relationship between them.

Approach:
Develop and validate a laboratory-based phenotyping workflow for quantifying Cucumis melo resistance to Bemisia tabaci and CYSDV. Identify the mode of inheritance of resistance traits in melon accessions exhibiting virus and vector resistance in field and laboratory screenings. Map quantitative trait loci (QTL) associated with resistance traits for melon accessions. Identify mechanisms of resistance and candidate resistance genes using F2:3 populations. Combine field validation of resistance traits with outreach to growers and industry.
