Production of corn and soybean products starts with research. With the industry’s third-largest research program and one of the widest bases of proprietary germplasm in the world, Great Lakes Hybrids and their parent company AgReliant Genetics LLC, can create unique hybrids to fit individual needs.

When AgReliant Genetics was formed in 2000, the world’s two largest farmer-owned corn breeding
companies (KWS AG and Limagrain) combined their very different proprietary germplasm bases. This
wide range of genetics has a high degree of variability due to the different breeding philosophies of the two sources. Great Lakes Hybrids and all the AgReliant brands will benefit in the future from a much deeper pool of resources to test for new hybrid combinations. For example, this year in the U.S., their research breeders will plant more than 300,000 plots and test nearly 37,000 different hybrid combinations.

One key to producing better hybrids, now and in the future, is the genetic variability of the germplasm base. Many of the larger companies have a wide amount of proprietary germplasm, but it is very narrow in scope. As the corn market progresses and patents limit company’s ability to cross lines with other industry germplasm, the performance of its hybrids could be sacrificed.

Moving the research to the field

With 26 breeding projects in Corn Belt maturities and a germplasm base as big as, and with more genetic variability than, any competitor, MidWestern farmers can expect superior hybrids from Great Lakes Hybrids and AgReliant Research.

Their research program has proven itself year in and year out in the elite National Corn Yield Contest,
where farmers using Great Lakes products have won more often than any other seed company in the
Midwest. Since 1985, nearly one out of every five farmers harvesting a Great Lakes entry has won a
national or state award.

For the upcoming planting season, Great Lakes Hybrids is pleased to announce the introduction of 24 new corn hybrids and 10 new soybean lines.

5300Bt – Superior yield and performance in a 103-day Bt hybrid. Girthy ear with some flex. Great
adaptability to soil types, fertility levels and planting populations.

5377 – The top early product tested last year in our research. Superior stress tolerance, great stalks and roots and it moves South well for its maturity. Very good natural tolerance to corn borer. A super choice at 103 days.

5395LL – Early LibertyLink® hybrid that’s best in a corn-soybean rotation. Very good stress tolerance.
Excellent yield and emergence.

5630RR – The Roundup Ready® version of our very successful NCGA yield champion 5668. 106 days.

5685RR – The Roundup Ready® version of our top selling hybrid, Quad-5. 106 days.

Quad-5Bt – The name says it all. The super performance and characteristics of Quad-5 with the added
protection of YieldGard® corn borer resistance. Quite simply, it’s the best 108-day Bt hybrid you can buy today.

5875CL – A short stature 108-day hybrid with true yield punch and the added flexibility of the Clearfield* production system. Best at high populations and high fertility. Good natural tolerance to corn borer.

5961 – The DOMINATOR. 5961 will dominate the corn belt in the 109-day maturity with super top-end
yield. Adapts well to all soil types and responds best to moderate to high populations and late nitrogen
applications. Great natural tolerance to corn borer.

5954RR – The Roundup Ready® version of 5961.

5966BtRR – A new 109-day stacked hybrid with very good yield for maturity and standability. Ear flexes well for moderate populations.

6020LL – The LibertyLink® version of our popular 110-day hybrid 6056.

5961Bt – If you thought 5961 would dominate, wait until you see the YieldGard® Bt version of 5961!
111 days.

6148RR – One of our top sellers last year was 6192. This is the Roundup Ready® version of that top
performing 111-day product.

6252CL – Stability in tough conditions is the trademark of 6252CL, a new 112 day hybrid with the
flexibility of the Clearfield* production system. Also has a very high rating for extractable starch.

6301Bt – A super 113-day Bt hybrid with exceptional yield punch. Great ear flex for best performance at moderate populations. Great standability and drought stress tolerance.

6344 – A new powerhouse yielder at 113 days. It’s consistent top-end non-GMO performance will give
P67 a run for it’s money – and it’s one point drier. Super ear flex for moderate populations. High
extractable starch.

6350BtRR – This is 6301Bt stacked with the Roundup Ready® system at 113 days in maturity.
