      Applications of germplasm conservation Plant materials (cell/tissue) of several species can be cryopreserved and maintained for several years, and used as and when needed. Cryopreservation is an ideal method for long term conservation of cell culture which produce secondary metabolites e.g. medicines Disease (pathogen) free plant material can. Germplasm resources conservation Germplasm of Pennisetum spp. (cultivated and wild) is conserved as 66, accessions in 97 genebanks across 65 countries, while germplasm of related genera Cenchrus spp. is conserved ( accessions) in 50 genebanks across 32 countries ().

    1. CONSERVATION STATUS OF SILKWORM GERMPLASM RESOURCES IN CHINA. 1. Introduction 2. Function of Silkworm Germplasm Resources. Silkworm germplasm resource is the necessary material base for the sustainable development of sericulture Sericulture industry is depending on the rich silkworm gene pool. Germplasm are living genetic resources such as seeds or tissues that are maintained for the purpose of animal and plant breeding, preservation, and other research resources may take the form of seed collections stored in seed banks, trees growing in nurseries, animal breeding lines maintained in animal breeding programs or gene banks, etc. Germplasm .

    THE CHALLENGES OF CONSERVING AND MANAGING PLANT GERMPLASM. The first challenge to a plant germplasm program is to acquire representative sets of samples of those species that merit conservation. Obtaining a genetically diverse collection usually means adequate sampling from the distribution range of the selected species. Crops already are . Germplasm refers to the hereditary material transmitted to the offspring through the germ is the total content of genes. It serves as the raw material for the breeder to develop different crops.. The main objective of germplasm collection is preservation of genetic diversity if a particular plant or genetic stock for its use in the future.

Ex -situ conservation is the conservation of components of biological diversity. The conservation of plant genetic resources (PGRs) is not limited to attaining and physically possessing the materials (collection and storage) but also includes ensuring the existence of these under viable conditions and with their original genetic characteristics intact.

Second, it can assist with the exchange of germplasm. Third, the techniques of molecular biology can be applied to the problems of managing and using germplasm. The fourth influence results from the increased demand for germplasm and conservation services by the biotechnologists.

For them, the most effective management practices have been those that combined highest. Genetic resources provide basic material for selection and improvement through breeding to ensure food security needs of the world’s rapidly raising population.

Conservation and utilization of plant genetic resources are important components of ex situ collections. The establishment of large, germplasm collections at ICRISAT genebank.

Yet an ever increasing world population, and the introduction of improved cultivars into the centers of crop diversity have caused serious erosion of much of the world's indigenous crop germplasm.

The seriousness of this problem has received growing national and international attention, especially during the past 10 years. Looking for Plant Germplasm. (Please see the Deadlines and Distribution us to help you have a successful ordering process).

Deadlines: The deadlines for requesting apple or cherry germplasm from our site are July 15 for summer bud wood and November 1 for dormant scion wood.

The deadline for requesting grape germplasm from our site is November 1 for dormant. Access and management of germplasm collections: Core collections for today and tomorrow (available as HTML version) Core collections offer a tool to improve access and management of germplasmcollections, and therefore are of great interest to those who use and manage plant genetic resources.

Cryopreservation in liquid nitrogen (LN, is the only technique currently available to ensure the safe and cost-efficient longterm conservation of the germplasm of problem species, including non. Germplasm conservation is the most successful method to conserve the genetic traits of endangered and commercially valuable species.

Germplasm is a live information source for all the genes present in the respective plant, which can be conserved for long periods and regenerated whenever it is required in the future.

Germplasm conservation significance, advantages, disadvantages are discussed. Also approaches, features growth and cryopreservation in germplasm conservation are reseached in this article The sum total of all the genes present in a crop and its related species constitutes its germplasm.

It is ordinarily represented by a collection of various strains and species. Therefore conservation of citrus germplasm is a priority, as recognized by development of a global citrus germplasm network in The International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) has recognized Citrus as an Annex 1 crop, and an initial meeting in began work to establish a global conservation.

The actual approach to forest-tree conservation and the methods used jointly depend on available genetic-conservation techniques and on the ultimate goal for perpetuating the germplasm. Citation: Millar, Constance I.
