This chapter describes the botany and taxonomy of banana, Musa genetic resources and their allied species available across the globe, the evolutionary history of various ploidies and genomes. In some, genebanks are costly to maintain and, as a consequence, are prone to economic decisions, Tissue culture techniques are of great interest. 3) and ex situ conservation in genebanks. This chapter is concerned with the different aspects of FGB establishment and how to conserve accession with FGB, with specific examples. In addition, botanical gardens are very important regarding to their roles in creating green space in urban spaces, tourist attractions, economical objects and well-being aspects of peoples. accessions). Consequently, global concern about, conservation is not appropriate or impossible, as well as the, In this paper, we first briefly review the main achievements obtained and problems faced, accessions are maintained in field genebanks. Particular emphasis is given to the development of in vitro conservation techniques in genebanks which are dedicated to the storage of vegetatively propagated crop plant species. The recent demonstration that embryogenic conifer cultures are amenable to cryopreservation indicates their obvious application for long-term storage of conifer tissues for clonal forestry programs (Gupta et al. It explains principles and describes the procedures needed for effective ex situ conservation. Ex-Situ Conservation 2. FGBs provide an opportunity for easy and ready access to conserved material for research and utilization. Their role is essential in the everyday life of men and animals, since they ensure plant reproduction. The importance of these issues to humankind is underlined in Article 1 of the objectives of the Convention on Biological Diversity (UNCED, 1992): It is generally agreed that a catastrophic loss of plant genetic diversity is occurring at this moment: species, gene combinations and alleles are being lost for ever and this process of genetic erosion is likely to become even more grave in the future. Such strategies include Some natural selection may take place within and between accessions, but management is designed to prevent it. /Height 139 This includes strategies for germplasm collection, establishment of virus-free germplasm, characterization, conservation, documentation and their potential utilization in banana improvement. in situ nature conservation, on-farm conservation and management, Identification and Inventories of priority species. The conservation of clones of rare, elite, and other important trees is of great importance in clonal propagation. Perspectives: However, the study should now progress to optimize a recovery medium, able to further improve shoot regrowth rates and plantlet formation in post-cryopreservation. Kolonja district areas show high species richness index, and the number of individuals distributed among species was more even (0.672) and equitable (0.857).
