The scientists developed Green Dixie Blackeye over a 10-year period by crossbreeding Bettergreen, a large cream-type green pea, and Bettergro Blackeye, a high-yielding popular blackeye-type pea. In 3 years of trials, Green Dixie Blackeye out-yielded top-producing Arkansas Blackeye #1 in 15 of 30 tests.
