however, the genetic differences of maintainer lines and the seventh restorers will be further studied by molecular technique.
然而,对于保持系和第7类恢复系而言,需借助分子手段进行研究以进一步了解其遗传差异。
according to this, germplasms were classified into two types, that was maintainer lines and restoring lines .
据此将香稻资源分为保持系和恢复系两类。
homologous sequences of mtdna were found between ms and maintainer lines by using 9 probes of maize and rice to hybridize with digested mtdna.
用9个玉米和水稻线粒体基因探针与酶切条带杂交发现,不育系与保持系线粒体dna的相同大小酶切片段含有相似的顺序。
