种质资源又被称为遗传资源,是农作物传递给后代的包含所有遗传信息的物质载体,是育种家赖以加工、改良和培育新品种的基本材料。由于气候的变化和人类活动的加剧,世界物种资源(包括野生植物物种资源)丧失的速度要比自然灭绝速度快1000倍,比新物种形成速度则快了100万倍。而且,这些物种一旦消失就永远不可恢复,这无疑是全人类的损失。1992年,联合国在巴西召开的环境与发展大会上,发起和签署了国际性《生物多样性公约》,强调所有国家必须进一
Germplasm resources, also known as genetic resources, are the material carriers that carry all the genetic information from crops to their descendants. They are the basic materials for breeders to process, improve and cultivate new varieties. Due to climate change and human activities, the world’s species resources (including wild plant species resources) are lost 1,000 times faster than natural extinction and 100 million times faster than new species. Moreover, once these species disappear, they will never be restored, which is undoubtedly the loss of all mankind. In 1992, the United Nations sponsored and signed the International Convention on Biological Diversity at the Conference on Environment and Development in Brazil, stressing that all countries must move forward
