作物品种资源是人类进行不断择优选育和自然选择而形成的,并世世代代传下来的栽培作物品种,在这些品种中蕴藏着各种性状的遗传基因,从而形成作物品种改良的重要物资基础。随着农业现代化生产的发展和人类生活不断提高,要求有更多的新品种来取代已经过时的质差的、古老低产的品种或补充新的物种。这是收集农作物品种资源的 Crop variety resources are the result of continuous selection, selection and natural selection of human beings. Cultivars of cultivated cultivars passed from generation to generation are contained in these cultivars, and genetic characters of various traits are contained in these cultivars, thus forming the important material basis for the improvement of crop varieties . With the development of modern agricultural production and the continuous improvement of human life, more new varieties are required to replace the old and poorly-produced varieties that have become outdated or of poor quality and supplement new species. This is the collection of crop resources
