Some of the earliest experiments in selective plant breeding were conducted around the turn of the 20th century by pioneering horticulturist Luther Burbank, who developed the first plumcot (a 50/50 plum-apricot hybrid) and the Santa Rosa plum, as well as hundreds of other varieties of fruits and vegetables, on his farm in Sebastopol. While the plumcot was too delicate for commercial success, Burbank broke new ground and planted the seeds for breeders to come.
