Breeding Corn for Positive Soil Microbial Interactions

Breeding Corn for Positive Soil Microbial Interactions. Captured live at the 2012 Organic Seed Growers Conference, Walter Goldstein, Mandaamin Institute, discusses data that shows some corn is receiving nitrogen that is fixed from the atmosphere by bacteria living in association with the corn. Hybrids made from these types of corn could produce more protein on less land and yield more than other types of corn grown under low nitrogen situations.

Breeding for Nutrition Part 3: Breeding Corn for Nutritional Value

This video is the third part of an eOrganic webinar on Breeding for Nutrition in Organic Seed Systems. This presentation was originally given live at the 2012 Organic Seed Grower's Conference. Walter Goldstein of the Mandaamin Institute discusses corn breeding for nutritional value and corn that is high in Methionine. This could replace the Synthetic Methionine in Chicken feed today.


It is probable we can achieve similar yields but with greater harvest of protein and oil and higher concentrations of methionine, lysine, oil, and protein.
• We also have increased carotenoid content which appears to be resulting in eggs and poultry meat that looks higher in carotenoids.
• We have developed new varieties that appear to be highly N efficient/N fixing and a number of them had competitive yields in our first year of hybrid trials.
• We are striving to bring this corn into the world appropriately.

Corn After Corn?

Growing corn after corn without fertilizer is a hard test for any corn inbred. Normal varieties do very poorly because they are adapted to heavy fertilizer inputs. These pictures show diverse breeding lines that did relatively well under such conditions while normal inbreds did poorly.

Nitrogen efficient Corn

More Nutrients per acre

Our better yielding hybrids produced more protein and oil per acre than conventionally bred hybrids because of their nutrient density.

Cross incompatibility can keep GMO pollen from contaminating non-GMO corn

Working with 3 genes: Ga1-S, Ga2-S, Tcb-1 and combinations. Inbred lines and hybrids. Build a strong and reliable barrier. Backcross genes into our best inbreds Yield testing. Working with USDA and NCSU..

Orange Corn = Orange Chickens

Not only does the corn help chickens produce oranger yolked eggs but our high carotene corn increases the carotene in the skin of chickens and hence its nutritional value too.

Orange Corn

We have been breeding varieties to have exceptional levels of carotene and it's becoming noticeable!

Better Nutritional Value including Methionine:

We have been breeding varieties to have exceptional levels of carotene and it's becoming noticeable!
Hybrids made with our new cultivars have high nutrient density. Conventionally bred hybrids generally have 7.5 to 9.5% protein on a total dry basis. Our hybrids generally have 9.3-10.8% protein. Conventional hybrids generally have 0.17 to 0.22% methionine on a total dry basis while our corn generally has 0.24 to 0.30%. High methionine corn we are developing is critical for organic poultry producers to wean them from the use of synthetic methionine.

In 2015 we had three sets of trials near Elkhorn, WI with 60, 90, and 78 of our hybrids and 6, 7, and 6 check commercial organic hybrids. On average our hybrids had 15-20% more protein, 11- 20% more oil, 19-20% more lysine, and 24-36% more methionine than did the commercial hybrids.
