An image of multiple chromosomes, taken from many cells. Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
Ernest Robert Sears (October 15, 1910, Bethel, Polk County, Oregon – February 15, 1991) was an American geneticist, botanist, pioneer of plant genetics, and leading expert on wheat cytogenetics. [1] Sears and Sir Ralph Riley (1924–1999) are perhaps the two most important founders of chromosome engineering [2] [3] in plant breeding. [4] [5]
Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. [1] It is used to improve the quality of plant products for use by humans and animals. [2] The goals of plant breeding are to produce crop varieties that boast unique and superior traits for a variety of applications.
Plant breeders use different methods depending on the mode of reproduction of crops, which include: Self-fertilization, where pollen from a plant will fertilise reproductive cells or ovules of the same plant; Cross-pollination, where pollen from one plant can only fertilize a different plant
Gene pyramiding is the simultaneous selection for and/or introduction of multiple genes during plant breeding. [1] Objectives of gene pyramiding includes 1) enhancing trait performance by combining two or more complementary genes, 2) remedying deficits by introgressing genes from other sources, 3) increasing the durability. [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.
Mating design is a schematic cross between the groups or strains of plants are made in a plant breeding that is common in agriculture and biological science. [1] The mating design in plant breeding has two main objectives: (1) to obtain information and understand the genetic control of a trait or behavior that is observed, and (2) to get the base population for the development of plant ...
Molecular breeding is the application of molecular biology tools, often in plant breeding [1] [2] and animal breeding. [3] [4] In the broad sense, molecular breeding can be defined as the use of genetic manipulation performed at the level of DNA to improve traits of interest in plants and animals, and it may also include genetic engineering or gene manipulation, molecular marker-assisted ...
