Research Project: RISK OF WESTERN CORN ROOTWORM ADAPTATION TO TRANSGENIC CORN

Location: Corn Insects and Crop Genetics Research

Project Number: 3625-22000-017-09
Project Type: Reimbursable

Start Date: Sep 01, 2009
End Date: Aug 31, 2014

Objective:
Identify molecular markers associated with resistance to Cry3Bb1 Bt corn in replicated colonies of WCR populations that are reared on isoline or Bt corn.

Approach:
A genome scan using a large number of SNP markers will be used to identify markers associated with the resistant phenotype. The SNP markers (about 1000) will be developed within the next year as part of a NRI grant recently awarded to a scientist at the Corn Insects and Crop Genetics Research Unit. Markers will be genotyped from a total of 960 individual western corn rootworms from replicated lines selected for Bt-corn resistance and their associated unselected control lines.
