一、建立种质资源数据库 种质资源是育种的基础,国内外育种机构都非常重视其收集和研究。据不完全统计,美、苏保存的各类作物种质资源超过30万份,国际水稻研究所保存水稻种质资源62,500份,国际小麦玉米改良中心保存种质资源74,000份。每份材料在不同的年份、地点,条件下进行多种性状的调查记载,组成
First, the establishment of germplasm database Germplasm resources is the basis of breeding, breeding institutions at home and abroad attach great importance to its collection and research. According to incomplete statistics, the United States and the Soviet Union have conserved more than 300,000 kinds of crop germplasm resources. The International Rice Research Institute maintains 62,500 rice germplasm resources and the International Wheat and Maize Improvement Center maintains 74,000 germplasm resources. Each material in different years, locations, conditions for the investigation of a variety of traits, composition
