The possibility of growing thornless varieties of plants was first discovered in the early 20th century, with significant advancements made in the 1930s. One notable example is the thornless blackberry, developed by horticulturist George W. McMillan at the University of Arkansas. This innovation stemmed from selective breeding techniques aimed at improving fruit production and making harvesting easier. Thornless varieties have since been cultivated in various regions worldwide, enhancing the appeal of many berry plants.
