Centralized Approach of Range and Medicinal Seed Collection for Completion of Genetic Variation in Natural Reources Gene Bank: (Case Study in some Part of Zagros Mountain)

Studies have shown that more than 250000 plant species growing around the world. Understanding of how many plant species could give well service to all of human, animals and environmental needs is not too easy. Plant breeder’s successfulness is related to variation within and between collected seeds of plant species. Experiences have shown that plant seed collections have to be managed to face with high amount of variation but less number of accessions (Core Collection). To reduce the budget requirement for seed collections, identifications, evaluations, storage, seed exchanging and data management, core collection has to be considered at first. If germplasm maintainers in all countries, looking after the seed collection only, and priorities not considered, problems in cold seed storage would be appeared. Overcoming the matter, for forage's seed collection, palatable characteristics, and for plant medicine's seed collection, extractable materials or essences has to be looked as priorities. Regarding these priorities, variation within plant species, decision making about plant seed collection's methods and selection of geographical seed collection sites which have high variation of plant species, are most necessary to look about. If seed collection continued without considering different limitations, this action will bring to gene banks some additional budget requirement and works, without significantly helping more plant production. In present paper, it has been tried to report and analyze a successful mission, which focused to collect range and medicinal plant seeds, in some parts of Zagros Mountain areas. Comparing with other methods of seed collection, presented method was shown to be much more effective, and could be followed as a good model in future.
