However, the transition from primitive to 'advanced' cultivars has had the effect of narrowing the genetic base. This has happened in two distinct ways: (1) selection for relative uniformity, resulting in 'pure' lines, multi lines, single or double hybrids, etc.
; and (2) selection for closely. A joint project of the International Board for Plant Genetic Resources and CIAT is underway to develop an in vitro based set of procedures for handling germ plasm, using cassava as a model, with.
The first is in relation to genetic stability. As already indicated, certain culture systems are less stable than others, being more prone to somaclonal variation (Scowcroft, ). Therefore, where there is a choice, in-vitro conservation of plant genetic resources generally avoids the use of cell and callus cultures.

Oct 12, · Off-site conservation is called as ex-situ conservation, which deals with conservation of an endangered species outside its natural habitat. In this method genetic information of cultivated and wild plant species is preserved in the form of in vitro cultures.
Although much of the focus in the plant sciences has been on the direct manipulation of plant genomes, biotechnology has also catalyzed a renewed emphasis on the importance of biological and genetic diversity and its conservation. The methods of biotechnology now permit a greater understanding of both species and genetic diversity in plants.

Introduction. Recent years have seen an increasing global concern over the loss of genetic resources of crop plants. Future progress in crop improvement and our food security depends, to a great extent, on immediate conservation of the rapidly vanishing crop gene.
propagation will contribute to the science of plant growth in vitro and to our understanding of how to direct that growth. This should, in turn, help in the design of future protocols for new species and should quicken the pace of the application of in vitro methods to plant conservation.

Plant Genetic Resources is an international journal that brings together the many diverse topics concerned with plant genetic resources. Each issue gives you access to peer-reviewed research papers on genetic variation in plants, both crop and non-crop, as well as on the technical, socio-economic, legal and geo-political aspects of PGR.
