The quick answer for regulatory studies is 90 days for GMO safety and 26 months for glyphosate (the active ingredient in Roundup agricultural herbicides) safety. The lengths of these studies are assessed and set by independent scientific bodies globally, in order to ensure product developers generate comprehensive data to appropriately determine the long-term safety of new products.
 
This question is similar to others on the site about safety testing and long-term safety. I’ve pulled together the following links to a few questions about GM safety that I thought you might find helpful:
 

• How long was Monsanto's study of GMOs, before they were "deemed" safe? How long was the longest study? Answered by Michael Koch, Monsanto
• Why has there never been a clinically controlled independent human feeding trial?  Answered by Bruce Chassy, University of Illinois at Urbana-Champaign
• … We need to know that eating GMO foods today won’t cause adverse health effects in 40 or 50 years. … Answered by Bruce Chassy, University of Illinois at Urbana-Champaign
• Will I get cancer? Answered by Dr. Dan Goldstein, Monsanto
• Do GMOs cause cancer?  Answered by Kevin Folta, University of Florida
• Can you give me a list of the latest 10 studies [on GMO safety]?  Answered by Peter Davies, Cornell University, and John Vicini, Monsanto

Also, following are links to two related questions that I answered about Roundup safety:

• Does glyphosate cause cancer?
• If roundup is safe for human consumption in trace amounts in food, then is it safe to drink it? If not, where is the line between safe levels and toxic levels of roundup?
