1876. The first U.S. pecan planting took place in Long Island, NY in 1772. In 1822, Abner Landrum of South Carolina discovered a pecan budding technique, which provided a way to graft plants derived from superior wild selections (or, in other words, to unite with a growing plant by placing in close contact). However, this invention was lost or overlooked until 1876 when an African-American slave gardener from Louisiana (named Antoine) successfully propagated pecans by grafting a superior wild pecan to seedling pecan stocks. Antoine’s clone was named “Centennial” because it won the Best Pecan Exhibited award at the Philadelphia Centennial Exposition in 1876. His 1876 planting, which eventually became 126 Centennial trees, was the first official planting of improved pecans. The successful use of grafting techniques led to grafted orchards of superior genotypes and proved to be a milestone for the pecan industry. The adoption of these techniques was slow and had little commercial impact—...
