The corporate serves as a helpful bridge between breeders and customers, enabling the researchers to realize perception about how well-liked sure varieties are earlier than pushing them out to be produced at bigger scales. “That’s something that we raise when talking to breeders,” says Sykes, who labored in sustainable agricultural initiatives earlier than beginning Main Beans. “For us to come in and say ‘we can take 50 pounds of whatever you’re testing and actually get feedback for you,’ that’s very exciting for these breeders.”

Sykes says she’s excited to assist get these newly-bred varieties into the arms of house cooks. “We’re not really informing the [bean] breeding process, but we’re identifying what cool work is going on out there and doing what we can to showcase that,” she says.
