What is germplasm plant conservation?
What is germplasm plant conservation?
Germplasm conservation is the most successful method to conserve the genetic traits of endangered and commercially valuable species. Germplasm is a live information source for all the genes present in the respective plant, which can be conserved for long periods and regenerated whenever it is required in the future.
What is germplasm PPT?
Germplasm is a living tissues from which new plants can be grown.It can be a seed or another plant part-a leaf,a piece of stem,pollen or even just a few cells that can be turned into the whole plant. It contains the information for a species genetic make up,a valuable natural resources of plant diversity.
What is germplasm in plant?
The sum total of hereditary material i.e. all the alleles of various genes, present in a crop species and its wild relatives is referred to as germplasm. This is also known as genetic resources or gene pool or genetic stock. Germplasm includes both cultivated and wild species and relatives of crop plants.
Why there is a need of plant germplasm conservation?
Germplasm serves as the raw material for the breeder to produce various crops. Therefore, conservation of germplasm has importance in all breeding programmes. It is very crucial to conserve the endangered plants otherwise some of the important genetic traits possessed by the primitive plants may be lost.
What is germplasm and its types?
Kinds Of Germplasm. The sum total of all the hereditary material is referred as germplasm.In other words, gene pool refers to a whole library of different alleles of a species Germplasm or gene pool is the basic material with which a plant breeder has to initiate his breeding programme.
How many types of germplasm are there?
Organizations Associated with Germplasm: There are two types of organizations, viz. International and National which are associated with germplasm. International Plant Genetic Resources Institute (IPGRI), Rome, Italy coordinates at global level.
What is the best method to conserve genetic material of wildlife?
Ex situ conservation is the preservation and propagation of species and populations, their germ cell lines, or somatic cell lines outside the natural habitat where they occur. This method maintains the genetic diversity extant in the population in a manner that makes samples of the preserved material readily available.
Who gave germplasm theory?
August Weismann
Germ-plasm theory, concept of the physical basis of heredity expressed by the 19th-century biologist August Weismann (q.v.).
