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 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
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 ...
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.
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]
The BLUPF90 family of programs is a statistical software package used in quantitative genetics for animal and plant breeding. [1] [2] It can fit mixed models using restricted maximum likelihood as well as Gibbs sampling to estimate variance components, and predict breeding values via best linear unbiased prediction (BLUP).
A key event in the conservation of plant genetic resources was the establishment of the International Board for Plant Genetic Resources (IBPGR) (now Bioversity International) in 1974, whose mandate was to promote and assist in the worldwide effort to collect and conserve the plant germplasm needed for future research and production. IBPGR ...
