农业的起源是人类为了自我生存而对作物种质资源利用的过程。种质资源是作物新品种培育及育种研究最重要的物质资源。农业的每一次重大突破,无一不得益于关键性种质材料的发掘与利用。粮食持续增产主要生产措施固然重要,而优良品种却是首要因素。发达国家良种的贡献率已超过50%。选育良种主要靠作物种质资源基因的多样性,目前任何高新技术都不能创造基因,
The origin of agriculture is the process of human utilization of crop germplasm resources in order to survive. Germplasm resources are the most important material resources for cultivating and breeding new crop varieties. Every major breakthrough in agriculture has benefited from the discovery and utilization of key germplasm materials. The main production measures continue to increase grain production is important, but the fine varieties are the primary factor. The contribution rate of developed countries has exceeded 50%. Breeding mainly depends on the variety of crop germplasm resources genes, at present no high-tech can create genes,
