The 1991 Convention specifies that the breeder's right must be granted for at least 20 years from grant date for perennial crops and at least 25 years in the case of varieties of trees or vines. In the 1978 convention minimum duration of breeders rights are 15 years for perennials and 18 years for trees and vines.
Tree breeding is the application of genetic, reproductive biology and economics principles to the genetic improvement and management of forest trees. In contrast to the selective breeding of livestock, arable crops, and horticultural flowers over the last few centuries, the breeding of trees, with the exception of fruit trees, is a relatively recent occurrence.
Plant breeders' rights (PBR), also known as plant variety rights (PVR), are rights granted in certain places to the breeder of a new variety of plant that give the breeder exclusive control over the propagating material (including seed, cuttings, divisions, tissue culture) and harvested material (cut flowers, fruit, foliage) of a new variety for a number of years.

PSA: The Sill's fruit trees have already reached maturity, meaning that you won't have to wait an entire decade for a fruit harvest, you'll just have to wait until the fruit's peak season. Shop ...
The breeder hopes for desirable traits to be bred with other cultivars – a process known as mutation breeding. Classical plant breeders also generate genetic diversity within a species by exploiting a process called somaclonal variation, which occurs in plants produced from tissue culture, particularly plants derived from callus.
Trees and shrubs, particularly evergreens, provide perches for birds to rest and shelter from rain, snow, wind, and predators. Make a brush pile in an out-of-the-way spot in the yard with trimmed ...
