Current Status of Genetic Resources Conservation, Characterization and Utilization uri icon

abstract

  • Plant Genetic resources (PGR) are the most important components of biodiversity. PGRinclude primitive forms of cultivated plants and landraces, modern cultivars, obsoletecultivars, breeding lines and genetic stocks, weedy types and related wild species (IPGRI,1993). Genetic variation must be conserved to combat new pests and diseases, and toproduce better adapted varieties for the changing environments. Seed conservation has vitalrole in preservation of genetic variability, as it is simple to handle, cost-effective andcapable of maintaining genetic stability over long time periods. The most importantcomponents of ex situ collections are conservation, characterization and utilization ofconserved germplasm
