SCRI Project Updates

IYSV & Thrips Tolerance

 

“Ensuring U.S. Onion Sustainability: Breeding and Genomics to Control Thrips and Iris yellow spot virus”

 

Project Director – Dr. Mike Havey at mjhavey@wisc.edu

 

[ Supported in Part by USDA-NIFA-SCRI Project No. 2008-04804 ]

 

 

Goal:  Establish collaborative research among growers, extensionists, 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 resistances to thrips and IYSV; Validation of phenotypes and distribution of selected germplasms;  Cost-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 resistances.

 

·  Outreach – Outreach to the onion community; Development of web-based bioinformatic and educational resources; Undergraduate and graduate student training.
