Plant breeding is the use of genetic principles to create plants with greater human utility. This is done by choosing plants that are deemed to be attractive or valuable economically or artistically, first by regulating the mating of those chosen individuals, and then by choosing particular individuals from the offspring. Such procedures, when carried out repeatedly over many generations, have the capacity to alter a plant population's hereditary composition and value well beyond what was naturally possible in earlier populations. The focus of this article is on using genetic principles to improve plants; the article heredity discusses the biological aspects of plant breeding. See genetically modified organism for more information on transgenic plants.

The practise of breeding plants has been around from the very beginning of agriculture. People probably started identifying different levels of plant excellence in their fields not long after the first cereal grains were domesticated, and they started saving seed from the best plants to grow new crops. These hesitant selection techniques served as the basis for early plant breeding techniques. Early plant breeding techniques had obvious results. The majority of modern types are so different from their wild ancestors that they cannot thrive in the wild. In some instances, the cultivated forms are in fact so radically different from their wild relatives that it is challenging to even determine who their ancestors were .
From an evolutionary perspective, these amazing changes were made by early plant breeders in a relatively brief period of time, and the rate of change was likely higher than for any other evolutionary event. Gregor Mendel developed the fundamental ideas of heredity using pea plants in the middle of the nineteenth century, laying the groundwork for scientific plant breeding. A start was made toward using genetic inheritance laws to improve plants when they were further defined in the early 20th century. One of the most important findings from the brief history of scientific breeding is that there is a huge richness of genetic variability present in the world's plants, and that this is just the beginning .
Self-pollinated species have been bred mostly by deliberate hybridization between carefully chosen parents since the turn of the 20th century. The goal of hybridization is to integrate advantageous genes from two or more different varieties in order to create pure-breed offspring that are more superior in many ways than their parents. However, genes always exist in a group called a genotype with other genes. The main challenge for plant breeders is to effectively manage the massive amounts of genotypes that appear in the generations after hybridization .
The first-generation offspring of a cross between parents with opposing genotypes are known as hybrid varieties. A hybrid variety is distinct from a variety created through hybridization, as explained in Chapter 10 for crops that are self-pollinated. If the parents are homozygous, the hybrid genotype is accurately duplicated in every plant by the F1 generation of the hybrid variety (pure lines or inbred lines). A line with genes from both parents is chosen by hybridization in self-pollinated crops after several generations of inbreeding .
Due to the large number of line-to-line tests required to determine hybrid performance, testing inbred lines for their combining potential is the most restricting step in the F1 hybrid breeding process. We suggest a brand-new approach to F1 hybrid breeding that allows a large number of line-to-line crosses to be evaluated for their hybrid performance. From heterozygous populations, inbred lines (ideally doubled haploid, or DH), are created, genotyped, and maintained. Random inter-pollination of several lines is done, and the offspring are then looked at .
New varieties created by commercial plant breeding organisations are frequently distributed through seed associations, however many reputable businesses advertise their goods without adhering to the formal certification procedure. New kinds may be trademarked in some nations, especially in Europe, for up to 15 years or longer. During this time, the breeder has the sole right to produce and market the variety.
