遗传变异何以是一种资源遗传资源这一概念常常是根据弗兰克尔和贝纳特(Frankel和Bennett,1970)所著的《植物遗传资源》一书而来.不过,作物及其近缘野生种的遗传变异是否为一种资源似尚未为人们所充分理解.包括水稻在内的栽培作物之所以相对地具有稳定的特征,是因为它潜在地存在着遗传物质(简称遗传质).遗传质指:使作物在遗传上具有的全部基因型,它既存在于核基因中,也存在于细胞质中.但是,若仅指作物的某一特性时,所谓遗传质仅指控制该性状的基因.人们为使水稻的遗传资源不断丰富,防止枯
Genetic Variation Is What It Is A Resource The concept of genetic resources is often based on the book Plant Phytology, by Frankel and Bennett (1970), but crops and their associated wild species Genetic variation is not yet understood as a resource.Cultivated crops, including rice, are relatively stable because of the potential existence of genetic material (genetic material for short) : All the genotypes that make a genetically inherited, both in the nuclear gene as well as in the cytoplasm, but when referring only to one trait of a crop, the so-called genetic element refers only to the gene that controls that trait Enrich the genetic resources of rice to prevent the dry
