Additionally at this time he published perhaps his most important publication, the 1960 book "Principles of Plant Breeding", [11] which was translated into 17 languages, and was the principal plant breeding book for at least a generation. A second edition was published in 1999.
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.
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.
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 ...
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]
Another disadvantage associated with the double haploidy is the cost involved in establishing tissue culture and growth facilities. The over-usage of doubled haploidy may reduce genetic variation in breeding germplasm. Hence one has to take several factors into consideration before deploying doubled haploidy in breeding programmes.
