Germplasm Preservation And Propagation; The Foundation Of Agricultural Development –A Review

Abstract

Abstact: The whole set of genetic material of a species of plants is known as germplasm of the organisms. Through various breeding techniques the germplasm of various plant species can be stored or preserved for future plant development. The techniques of gerplasm preservation vary from cryopreservation, slow growth cultures, DNA clones, in-vitro storage, cold storage, super cold storage, field preservation to the use of artificial seeds. The major purpose of germplasm preservation is to preserve rare and endangered species of plants around the globe for future propagation and development; hence germplasm is the foundations of agricultural productions. Today's preservation techniques have been developed on the base of natural occurring phenomena like sporulation, germination, hibernation and adaptation which are found in different animals and in micro organisms. All the simple and sophisticated preservation techniques are today being used in giant projects that are on going.
