Plant breeding is the science of changing the traits of plants in order to produce ... These legal definitions of stability contrast with traditional agronomic usage ...
Plant breeding started with sedentary agriculture, particularly the domestication of the first agricultural plants, a practice which is estimated to date back 9,000 to 11,000 years. Initially, early human farmers selected food plants with particular desirable characteristics and used these as a seed source for subsequent generations, resulting ...
Plant propagation is vital to agriculture and horticulture, not just for human food production but also for forest and fibre crops, as well as traditional and herbal medicine. It is also important for plant breeding. [2] [3]
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.
The Plant Patent Act of 1930 gave plant breeders the same status as mechanical and chemical inventors had through patent law. [2] The early objectives of the breeding stations were to develop new varieties to better satisfy the American demand for better dessert, canning and freezing varieties. [1]
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
A landrace is a domesticated, locally adapted, [2] [3] [4] often traditional [5] variety of a species of animal or plant that has developed over time, through adaptation to its natural and cultural environment of agriculture and pastoralism, and due to isolation from other populations of the species. [2]
The relevance of DHs to plant breeding has increased markedly in recent years owing to the development of protocols for 25 species. [2] Doubled haploidy already plays an important role in hybrid cultivar production of vegetables, and the potential for ornamental production is being vigorously examined.
