1979年2月在合肥召开的全国农作物品种资源科研工作会议,提出了目前我国品种资源研究工作的二十字方针:广泛收集,妥善保存,深入研究,积极创新,充分利用。这五个方面,从横的来说是品种资源研究的全部任务,从纵的来说又是品种资源研究的全过程。其中,广泛收集是品种资源工作的基础。如果不占有丰富的资源,其余四个方面就是空的。近十多年来,由于极左路线的严重影响,不仅中断了品种资源的考察和征集,而且有的地方使业已收集到的珍贵材料大量丢失。今后,随着经济和科学技术的发展,自然生态环境的改变,作物品种资源还将逐渐减少。因此,如不抓紧时机突击收集,许多宝贵材料可能从此绝迹
February 1979 in Hefei held a national conference on crop resources scientific research work, put forward the current twenty-character principle of our country’s variety resources research: extensive collection, properly preserved, in-depth study, positive innovation, make full use of. These five aspects are all the tasks of variety resources research from a horizontal perspective and the whole process of variety resources research vertically. Among them, extensive collection is the basis for the work on variety resources. If you do not have rich resources, the remaining four aspects are empty. In the past decade or so, due to the serious impact of the ultra-leftist line, not only the investigation and collection of variety resources have been interrupted, but also a great deal of lost precious materials have been collected in some places. In the future, with the development of economy and science and technology and the change of natural environment, the resources of crop varieties will also be gradually reduced. Therefore, if we do not seize the opportunity to assault, many precious materials may disappear from this
