Biotechnology - its role in conservation of ginger resources of spices

Abstract

Plant genetic resources are non-renewable and are most essential of the world's natural resources. Secure genetic stocks are fundamental requirement for plant breeding. The advances in biotechnology, brought about by combination of in vitro technology. genetics and molecular biology are changing the way that will look at gene pools and their utilisation for crop improvement. Most of the world's germplasm is currently maintained in field gene banks. In vitro gene bank is a novel system of conservation of genetic resources especially those which are propagated vegetatively and/or have recalcitrant seeds. In vitro base gene bank where cultures are maintained cryopreserved it., stored in liquid nitrogen at or near a temperature of -196°C
