"C" is for Coker's Pedigreed Seed Company. Coker's Pedigreed Seed Company had its origins in the efforts of David R. Coker to develop and market a highly productive variety of upland cotton.. The focus was on cotton, but Coker expanded the project to include corn, oats, rye, peas, sorghum, and eventually tobacco. Originally managed as a division of J.L. Coker and Company, the Pedigreed Seed Company was incorporated in 1918 as a separate business with headquarters in Hartsville.
