I think you should see if there is a source for news on the growing of Roundup Ready grain. I haven't seen the current issue of MEN but here is what the USDA said about the roundup ready wheat found in Oregon recently:

"There are no GE wheat varieties approved for sale or in commercial production in the United States or elsewhere at this time." (May, 2013)

I had to do a google cache search since much of the USDA website is not available because of the shutdown. It is linked below thru firefox but the link worked in Chrome, also.
