Germplasm are living genetic resources that can serve as bearers of heredity, and include germ cells and their precursors, plant seeds and pollen, animal sperm, oocytes, embryos, and larvae. Cryopreservation refers to the preservation of biological materials at extremely low temperatures, typically using solid carbon dioxide at -80°C or liquid nitrogen at -196°C for freezing, and cryogenic storage in perpetuity. Germplasm cryopreservation is an important technology applied for medical treatment, maintenance of biological diversity, preservation of valuable genetic resources, assistance of breeding programs, and conservation of imperiled species. This extension publication is intended to introduce the basic concepts, history, principles, and applications of germplasm cryopreservation technology.

The maintenance and preservation of biodiversity is going through the processes of conservation and restoration of disturbed ecosystems and habitats, as well as the preservation and recovery of species. Genetic diversity means the variety and total number of genes contained in plant and animal species and microorganisms. Genetic diversity is the basic unit of diversity, which is responsible for differences between individuals, populations and species. Genetic diversity is very important for the preservation of biodiversity and can be saved in several ways. Part of the germplasm is maintained through breeding programs as they evaluate germplasm stored and used as a source of needed diversity. The Convention on Biological Diversity is one of the most important international agreements to protect nature and conserve genetic resources. International treaties governing the use of genetic resources for food and agriculture are a way to ensure the conservation and sustainable use of plant resources for food and agriculture, and to regulate the rights of farmers.

Highly significant genetic resources of matoa potentially for breeding program in Papua are being threatened as a result of cutting down trees for fruit harvesting and of forest exploitation for timber. Besides the loss of genetic resources facing now, other major problems should be consider for conservation and domestication of this fruit tree species i.e. lack of silviculture and agronomy knowledge for further breeding programs; matoa production only for local market; and inadequate government policy for matoa breeding program. Strategy developed for matoa conservation and domestication should also concern about time limited due to the fast loss of genetic poll. This paper provides a general overview of strategy for conservation and domestication of <em>Pometia pinnata</em> with special reference to Papua.</p>

Global Agreement

In an era of a rapidly shrinking biological resources, the Convention on Biological Diversity (CBD) is a historic landmark, being the first global agreement on the conservation and sustainable use of biological diversity. The CBD is one of the few international agreements in the area of natural resource conservation in which sustainability and equitable benefit-sharing are central concerns. The CBD links traditional conservation efforts to the economic goal of using biological resources sustainably and sets forth principles for the fair and equitable sharing of the benefits arising from the use of genetic resources, notably those destined for commercial use. Importantly, the CBD also gives traditional knowledge its due place in the sustainable use of genetic resources. The CBD also covers the rapidly expanding field of biotechnology, addressing technology development and transfer, benefit-sharing and biosafety, in an equitable framework. In the coming years, the CBD is likely to have major repercussions on the way biodiversity is conserved and benefits thereof, shared between the developing and developed worlds. The following commentary on the CBD has drawn heavily from a document produced by Secretariat of the Convention on Biological Diversity, at the United Nations Environment Programme. Articles 1 to 21 of the CBD have also been reproduced here in order to disseminate knowledge regarding the principles of the CBD-Editor.

Recently, highly productive breeds of various species of domestic animals have been used in livestock production, which has resulted in the destruction of indigenous breeds of domestic animals around the world, even in our area. This is the first reason why indigenous races and strains have been endangered. Another reason is that domestic, indigenous breeds were crossed with specialized breeds, which were imported, and in that way their genetic diversity was negatively affected. Resistance is lost, adaptation to the conditions in which they were created, the ability to survive in nature. Indigenous breeds of different species of domestic animals, which are recognized in the Republic of Srpska (BiH) are gatačko cattle and buša (cattle), Vlašić pramenka, Podveleška pramenka, Kupres pramenka (sheep), domestic Balkan horned goat (goats), Bosnian mountain horse (horses), mangulica (pigs) and pogrmuša hen or živičarka hen (poultry). By acceding to international conventions, BiH /Republic of Srpska has committed itself to establishing a system of measures that will enable the conservation of biological diversity and the protection of indigenous and endangered breeds of domestic animals. The choice of a strategy for the conservation of diversity, the establishment of an adequate conservation scheme, and the implementation of a conservation strategy are some of the key elements of any process for the conservation of genetic diversity. Preservation of autochthonous and protected breeds of domestic animals is possible through preservation in the original environment (in situ) and preservation outside the original environment (ex situ). There is a possibility of combining these models of conservation of animal genetic resources.

Characterization and evaluation of the genetic resources provide breeders with valuable information on an effective utilization of the genetic resources in breeding programs. In this paper we present the results of different research programs aimed at identification of superior genotypes among MRI gene bank accessions, regarding stress tolerance (drought and herbicides), better nutritional quality (phosphorus) and specific traits (cytoplasmic male sterility - CMS). Fifty-two genotypes were identified as a potential source for drought tolerance. Considering herbicide tolerance only genotypes with resistance to the Pivot were found. Within 100 sources of CMS in the collection S cytoplasm was identified as the predominant type. Phytate analysis of 60 maize populations identified three groups of populations - with low (8), intermediate (25) and high (27) phytate content. The results of these researches, which are a part of pre-breeding activities, will be included in MRI breeding programs, with the aim of developing new genotypes with improved traits important in commercial maize breeding and seed production.
