Seed Research and Development
CHS is the only major processor that maintains its own hybrid seed division, staffed by seed genetics experts and complete with comprehensive nursery, greenhouse and laboratory facilities. Year after year, we put thousands of hybrids through rigorous lab tests and field trials in order to fine-tune the most desirable characteristics based on customer input and market demand. Traits like rich flavor, firm kernels, large size and unique shaping, not to mention improved yields and consistent quality. And all our sunflower seed development is free from any genetically modified source.
