As planning for the 2026 crop season begins, many growers are thinking beyond yield alone. Consistency, standability and dependable performance across a variety of field conditions matter just as much as top-end numbers. Those priorities shaped the development of Stine’s MX Series Corn lineup.
Backed by our elite, research-driven breeding program, four MX Series Corn brand hybrids — MX451-0 Brand, MX481-G Brand, MX521-G Brand and MX551-G Brand — give growers practical options as they plan for the year ahead. Rather than chasing a single standout trait, each product balances agronomic strength and yield potential to perform under real farming conditions, whether that means pushing populations or managing tougher acres.
“These hybrids weren’t developed for one perfect scenario. They’ve been tested across environments and management styles, so growers know what to expect when they put them in the ground.”
Tom Larson, Stine director of agronomy
Testing is a key reason why growers continue to trust the MX Series Corn lineup. Whether you’re managing tough acres or pushing populations on high-yield ground, these hybrids deliver consistent performance supported by data. Because each product advances through Stine’s Elite Yield Trials, growers can better understand how they will perform on their own farms before planting season arrives.

Designed with growers in mind
The MX Series Corn lineup reflects years of focused breeding and rigorous field research. Each product has been evaluated through Stine’s Elite Yield Trials, where they are challenged across locations, soils and stress conditions before earning a place in our portfolio.
That process helps ensure these hybrids are ready for the realities growers face each season. From early emergence to late-season standability, MX Series Corn was developed to support consistent performance across a wide range of management styles and growing conditions.
“We don’t move hybrids forward unless they prove they can hold up. Strong emergence, standability and consistent performance are nonnegotiable for us because they’re nonnegotiable for growers.”
Myron Stine, Stine Seed Company president
Extensive testing gives growers more confidence as they plan for 2026, especially when input costs are high and every acre matters. Talk to your local Stine rep or visit our website to learn more about the full MX Series Corn lineup.
