种质资源即作物品种资源,是指栽培品种、近缘野生植物、人工创造或自然形成的特殊变异型,蕴藏着各种性状的遗传基因。它既是培育良种的物质基础,又是生物学理论研究的重要材料。在作物种质资源中,大多数是用种子繁殖的,因保存种子比其它形式保存种质资源来得方便和经济。用种子来保存种质 Germplasm resources that crop varieties of resources, refers to cultivars, relatives of wild plants, artificial or natural formation of special variants, contains a variety of traits of genetic genes. It is not only the material basis for nurturing seeds, but also the important material for the study of biology theory. Among crop germplasm resources, the majority are seed-borne, which is convenient and economical because of the preservation of seeds over other forms of germplasm preservation. Use seeds to preserve germplasm
