TAMZ107 Stands Out in a Wet Year for Corn Ear Rots

Sometimes two ears of corn can tell an important plant-breeding story.

Ears from the 2026 Taylor, Texas, corn hybrid trial. TAMZ107 (top) remained free of visible ear-rot symptoms, while an unnamed commercial hybrid (bottom) showed severe ear-rot damage.

Both ears pictured came from a 2026 corn hybrid trial near Taylor, Texas—one location in our multilocation testing program. The ear on top is TAMZ107, developed by Dr. Wenwei Xu, Texas A&M AgriLife Research corn breeder at Lubbock. The ear on bottom is an unnamed commercial hybrid.

Frequent rainfall and humid conditions during the 2026 growing season have favored corn ear rots across parts of Texas. The commercial ear shows severe ear-rot symptoms, with Fusarium among the predominant ear-rot pathogens observed this season. All commercial hybrids in this trial showed some ear-rot damage, while the TAMZ hybrids remained free of visible symptoms.

The importance of this comparison is not the identity of the commercial company. It is the value of years of public plant breeding. Dr. Xu selected resistant inbred parents and combined them to produce TAMZ hybrids adapted to Texas conditions. TAMZ107 has been tested for several years and is now ready for release and fits an organic program because it is GMO free and adapted to organic conditions.

Genetic resistance is especially valuable for organic farmers because it arrives in the seed. The plant begins the season with its own protection rather than depending on a treatment after disease develops. Resistant hybrids can also benefit any farmer facing difficult weather and disease pressure.

The TAMZ hybrids will be featured during the Field to Fiesta Corn Tour on Wednesday, August 12, beginning at 9 a.m. at the Halfway Research Center in Halfway, Texas. The tour will include the research center and nearby farm fields, followed by a sponsored lunch.

Topics will include heat during pollination, corn borers and earworms, drought tolerance, ear rots and herbicide drift. For attendance information, contact Extension Agronomist Kristie Keys at kristie.keys@ag.tamu.edu. View the program announcement.

Corn Breeding – Not an Easy Process

In the world of organic agriculture, the continuous development of improved corn varieties is crucial for addressing the evolving challenges faced by farmers. This November, Dr. Wenwei Xu, a TAMU Research Corn Breeder from Lubbock, and I traveled to work in the Winter Corn Nursery in Ponce, Puerto Rico. Our mission involved carefully collecting pollen from specific corn varieties and crossing them onto the silks of other varieties to produce hybrids for future variety production.

The Winter Corn Nursery plays a vital role in accelerating the breeding process by allowing researchers to conduct additional growing cycles during the off-season. This enables breeders to make faster progress in developing new varieties with desirable traits such as brown mid-rib, improved leaf structure for weed suppression, drought tolerance, high antioxidant production, and enhanced silage production capability. By utilizing winter nurseries, breeders can significantly reduce the time required to bring new, improved varieties to market, ultimately benefiting organic farmers and the agricultural industry as a whole.

The work of corn breeders is essential for advancing organic agriculture and addressing the unique challenges faced by organic farmers. Through careful selection and crossing of varieties with known traits, breeders aim to develop new hybrids that combine multiple desirable characteristics. These efforts result in corn varieties that are better adapted to organic growing conditions, more resilient to pests and diseases, and capable of producing higher yields with improved nutritional profiles. By continually refining and enhancing corn genetics, breeders contribute to the sustainability and productivity of organic farming systems, helping to meet the growing demand for organic products while supporting the long-term viability of organic agriculture.

Organic Corn Resources

Finding a corn variety adapted to Texas extremes can be very difficult. At this time, I just don’t know of too many certified organic corn varieties that can make it through the difficult hot nights in most of Texas except maybe the northern panhandle area of Texas. Even in those area many growers have tried to bring in corn varieties popular in the Midwest and they just don’t yield well.

That said, I have tried to list varieties that Texas organic growers have grown and continue to grow. The companies listed may or may not have varieties adapted to Texas, but you have their contact information to check. If you see anything I need to add, change or delete please let me know. This is an ongoing project and one that will continually be updated and changed.

Seed Contacts:

This list does not necessarily mean that these companies have corn varieties adapted for Texas. Companies continue to develop varieties that work in areas they have not traditionally grown in and so some testing helps know and use new materials.
