CORN PRODUCTS

Renk Seed has been breeding corn since the 1960s, so we thoroughly understand the breeding process. Every year we evaluate 80,000+ data points from our own breeding material, as well as the breeding material of our strategic partners. We plant plots throughout the Midwest and Great Plains to expose our genetics to many different environments. This helps us select the best products and ensure that when you plant Renk Seed, you will be getting the most effective and stable performance.
