在西藏自治区拉萨市林周县，有一片包含四千多个品种的青稞种质培育基地。达瓦顿珠，是西藏农科院农业研究所副研究员，三年前，正是在他的努力推动 下，这片世界上最大的青稞种质资源基地最终建成。 种质资源，已经非常明确地被世界各国认定为一个国家，一个民族的"农业命根子"和"战略基因库"。同样是青稞，为什么要把四千多个不同的品种都要保留 延续下来？因为不同品种的青稞，包含有不同的基因遗传密码和优缺点。举例来说，假如突然暴发一种新的植物瘟疫，现在大规模种植的青稞全部得病，可 能引发当地粮食危机，这时候就可以去品种丰富的种质基地里找，很可能某一种不起眼、半野生的青稞亲戚，天生就携带抵抗这种瘟疫的基因。用它来做育 种材料，就能拯救全部的青稞，这就是"救命基因"。 青稞，是一种生长在青藏高原的大麦，对高原极端气候的极度适应性，使其早在三四千年之前，就成为藏族人民的传统主食，也因此，青稞对粮食安全至关 重要。 记者：青稞对于西藏的老百姓来说，分量有多重？ 达瓦顿珠：那就太重要了，必不可少或者只能依赖它。青稞既可以卖，又可以当货币，去换酥油换牛肉，这么换，所以它就是一切了。 记者：它又是货币，又是粮食。 达瓦顿珠：对，又是牲畜的饲料 ...
