水稻遗传资源是世界粮食安全的基础，包括地方品种、现代和淘汰品种、遗传资源、育种系和野生稻。菲律宾国际水稻研究所的国际水稻基因库保存着最大和最多样化的水稻种质。基因库的设施确保了这一重要多样性的长期保存。在田间研究中，已经确定了影响水稻种子长期生存力的因素，从而引入了改良的种质繁殖和再生实践。种质资源的保存价值可以从种质资源对水稻育种的有用性状和种质资源利用对水稻生产和生产力的经济影响两个方面来评估。分子标记的应用正在改变种质管理的观点。讨论了影响水稻种质资源获取和利用的国际政策.
Rice genetic resources, comprising landrace varieties, modern and obsolete varieties, genetic stocks, breeding lines, and the wild rices, are the basis of world food security. The International Rice Genebank at the International Rice Research Institute in the Philippines conserves the largest and most diverse collection of rice germplasm. The facilities of the genebank ensure the long-term preservation of this important diversity. In field research, factors that affect long-term viability of rice seeds have been identified, leading to the introduction of modified practices for germplasm multiplication and regeneration. The value of conserved germplasm can be assessed in terms of useful traits for rice breeding and the economic impact that germplasm utilization has on rice production and productivity. The application of molecular markers is changing perspectives on germplasm management. International policies affecting access to and use of rice germplasm an discussed.
