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.
Classical plant breeding uses deliberate interbreeding (crossing) of closely or distantly related individuals to produce new crop varieties or lines with desirable properties. Plants are crossbred to introduce traits / genes from one variety or line into a new genetic background.
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.
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 ...
Orissa University of Agriculture and Technology.. Trilochan Mohapatra was born on 20 April 1962 at Kharibil village in Cuttack in the Indian state of Odisha. [2] After completing early schooling at Laxmi Narayan High School at Eranch near his home village in 1978, he did his pre-university studies at Ravenshaw College (present day Ravenshaw University) in 1980.
Classical genetics is the Mendelian genetics or the older concepts of the genetics, which solely expressed based on the phenotypes resulted from breeding experiments while the modern genetics is the new concept of genetics, which allows the direct investigation of genotypes together with phenotypes.
