IYSV & Thrips Tolerance
Project Director – Dr. Mike Havey at mjhavey@wisc.edu
[Supported in part by USDA-NIFA-SCRI Project No. 2008-048014]
Goal: Establish collaborative research among growers, extension agents, pathologists, and breeders to identify, validate, and deliver resistances to thrips and thrips-vectored Iris yellow spot virus (IYSV) in relation to the following objectives:
- Extension – Identification of resistance to thrips and IYSV; validation of phenotypes and distribution of selected germplasms; cotse-benefit estimates for thrips and IYSV resistances.
- Research – Biological diversity and inoculation protocols for IYSV; identification of SNPs in expressed onion sequences; production of a high throughput genotyping platform and a high-density genetic map of onion; association of SNPs with glossy-type foliage and/or thrips and IYSV resistance.
- Outreach – Outreach to the onion community; development of web-based bioinformatic and educational resources; undergraduate and graduate student training.
