有效的种质资源繁殖更新是保持作物异位保存种质资源活力和遗传完整性的首要工作。
Effective regeneration programmers are essential to maintain the viability and genetic integrity of ex situ seed collections of crop germplasm.
该结果也从另一方面证明，对于异质种质材料，低的发芽率更新标准是不利于确保种质遗传完整性的维持。
This result also indicated that a low germination percentage standard for regeneration is disadvantageous for maintaining the genetic integrity of heterogeneous accessions.
同样再假设该物种表型复制之所以世代遗传的机制，就是上述观点中的“不完整性”。
Suppose, also, that the mechanisms that copy phenotypes from each generation to the next are "imperfect" in the sense given above.
线粒体基因组作为细胞核外的一种遗传系统，具有完整性、多态性、自主性和小型性等独特的优点。
As a unique cytoplasmic genetic system, mitochondrial DNA (mtDNA) is a kind of complete, small, self-replica ting and diverse genome.
