Overview
Stine Seed Company is a family-owned company and the largest privately held seed company in the United States. For more than 40 years, Stine has been providing corn and soybean growers with the best genetics available in the industry. Being the country’s largest independent seed company means we have the ample resources and the flexibility to make timely decisions that ensure our research, products and programs are leading edge.
Research
When it comes to research, yield is what matters most. Our breeders and scientists take their cues from the tradition of company founder Harry Stine and strive to reach the next level of excellence in corn and soybean performance.
Today, Stine operates the industry’s largest soybean breeding program, developing genetics that comprise nearly two-thirds of the soybean genetics planted in the United States each year. Stine also operates one of the industry’s largest and most prolific corn breeding programs, developing and evaluating hundreds of thousands of unique hybrids per year.
Products
Stine leads the industry in the introduction of new soybean technologies, including Stine LibertyLink® GT27™, Roundup Ready 2 Xtend™ and Enlist E3™ soybeans.
Stine also offers an expansive lineup of corn products packaged with the industry’s leading traits, including Stine Agrisure Viptera® and Agrisure Duracade® brand corn, in addition to Stine’s revolutionary high-population corn (HP Corn®) and Elite conventional hybrids.
Agronomy
Success in the field goes well beyond putting the best seed in the ground. Knowing what, when and where to plant has just as much, if not more, impact on end-of-season yields. For that reason, Stine is equipped with a team of highly dedicated regional sales agronomists with reach across the country. This team is available to provide product and crop management knowledge to help growers maximize potential on every acre they farm.
