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.
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.
The breeder should also have definite goals with the choice of parents. Self-fertilizing are easier to maintain, but this could lead to misuse of seed. Some of the agronomy important, self-fertilizing crops include wheat, rice, barley, dry beans, soy beans, peanuts, tomatoes, etc.
Mutation breeding, sometimes referred to as "variation breeding", is the process of exposing seeds to chemicals, radiation, or enzymes [1] [2] in order to generate mutants with desirable traits to be bred with other cultivars. Plants created using mutagenesis are sometimes called mutagenic plants or mutagenic seeds.
Gartons Agricultural Plant Breeders in England was established in the 1890s by John Garton, who was one of the first to cross-pollinate agricultural plants and commercialize the newly created varieties. He began experimenting with the artificial cross pollination firstly of cereal plants, then herbage species and root crops and developed far ...
F1 hybrid (also known as filial 1 hybrid) is the first filial generation of offspring of distinctly different parental types. [1] F1 hybrids are used in genetics, and in selective breeding, where the term F1 crossbreed may be used.
However by July, 2017, OSSI had over 375 varieties of more than 50 crops bred by 36 breeders and being sold by 46 seed company partners. While varieties have been contributed by public sector plant breeders at universities and not-for-profit organizations, most OSSI varieties have been contributed by freelance plant breeders and seed companies.
Plant genetic resources that are conserved by any of these methods are often referred to as germplasm, which is a shorthand term meaning "any genetic materials". The term originates from germ plasm , August Weismann 's theory that heritable information is transmitted only by germ cells, and which has been superseded by modern insights on ...
