大麦是世界上最古老的粮食作物之一。在我国也有5000多年的栽培历史。其分布之广,适应性之强,为其它作物所不及。在长期自然和人工选择的进化过程中,形成了极其丰富多采的变异类型。努力发掘和利用蕴藏其中的优异种质或基因,提高我国的大麦育种水平,促进大麦生产,是摆在大麦品种资源工作者面前的一个重大课题。“七五”期间,我国已经完成了上万份大麦种质资源的编目和繁种入库工作,覆盖了我国现有大麦种质资源总量的80%以上。虽然“八五”期间小规模的编目、繁
Barley is one of the oldest cereal crops in the world. In our country also has 5000 years of cultivation history. Its wide distribution, strong adaptability, less than other crops. In the evolution of long-term natural and man-made choices, a very rich and varied type of variation has developed. Striving to discover and utilize the excellent germplasm or genes contained therein, improve the level of barley breeding in our country, and promote the production of barley is an important issue facing the barley variety resource workers. During the “Seventh Five-Year Plan”, China has completed the cataloging and breeding of tens of thousands of barley germplasm resources, covering over 80% of the total amount of barley germplasm resources in our country. Although “eight five ” during the small-scale cataloging, complicated
