Germplasm Conservation

  • P. M. Priyadarshan
Chapter

Abstract

Germplasm is a collection of various strains and species that accommodates total of all the genes present in a crop and its related species. Germplasm is the basic indispensable ingredient of all breeding programmes, and hence, collection, evaluation and conservation of germplasm types become an integral part of any breeding programme. Usually, the germplasm accessions are conserved in the form of seeds stored at ambient temperature, low temperature or ultralow temperature.
