本研究基于可有效鉴别籼粳基因型的插入/缺失(In Del)标记,用筛选出的23个多态性标记对云南农业大学稻作研究所保育的231份滇型杂交粳稻(滇粳杂)保持系材料具有的籼型遗传成分比例及遗传多样性进行了研究。研究发现,供试保持系材料的籼型遗传成份比率较低,都是Fi≤0.25。其中,具有籼型成分比例0云南农大稻作所>中国华东>国外>云南其他地方>楚雄州农科院>云南省农科院。
In this study, 231 Delian-type japonica hybrid rice (Dianjing hybrid rice), which were conserved in the Institute of Rice Research, Yunnan Agricultural University, were screened by 23 selectable polymorphic markers based on the In Del marker that can distinguish indica and japonica genotypes ) To maintain the lineage of the indica-containing genetic material composition and genetic diversity were studied. The study found that the proportion of indica-type genetic elements in test-maintainer lines was low, all of which were Fi≤0.25.
