The effective germplasm conservation programme is one, which shows genetic stability, easy handling, longer viable, and cost effective.
It is the conservation of ecosystem and natural habitats and the maintenance and recovery of viable population of species in their natural surroundings or as cultivated plants in farmer’s field as part of existing agro-ecosystems.
It involves the conservation not only of inter and intra specific diversity but also of whole ecosystems. It allows continuing of evolution and adoption of plant populations, which may develop new and potentially useful traits as a result.
It is the conservation of components of biological diversity outside their natural habitats.
A well dried seeds are packed in moisture proof containers such as thick polyethylene bags and /or laminated aluminium foil pouches and stored at low (5°C) and/or at sub-zero (-20°C) for medium and long term conservation.
Mango, litchi, jamun, jackfruit etc seeds are having shorter storage life.
It is one of the in situ methods of conservation wherein farmer conserves genetic diversity of locally developed traditional varieties with associated wild and weedy species or forms within traditional farming systems.
There are several genotypes, which have elite qualities like resistance to pests, high nutritive value, salt and drought tolerance etc. Hence conservation of germplasm helps in making use of such genotypes for further improvement of existing varieties.
40 plants should to be sampled to get better estimate in Chillies.
It is conserved in the form of seeds, vegetative parts, tissue and living plants
