We occasionally receive letters from folks who eschew the patenting of plants, or hybridization, or even of propagation using laboratory methods, such as tissue culture. Some insist that all heirloom cultivars must be open pollinated and true-breeding, which means they will reproduce faithfully from seed without hybridization. True-breeding is indeed a part of the heirloom definition, but not for many woody fruit cultivars.
