摘要
利用60Coγ射线辐照籼稻材料M804,获得了1个性状能稳定遗传的矮秆突变体MU101,对其形态学及细胞学方面进行了鉴定分析表明,该突变体田间表现植株矮化,叶色浓绿,株型紧凑,长势较强,抽穗和分蘖正常,节间数较野生型减少2个,各节间不按比例缩短。该突变体可作为一个特殊类别材料进行深入研究,同时也为该突变基因的定位克隆、遗传机理研究及利用分子标记辅助选择培育理想株高的新品种奠定了基础。
A rice dwarf mutant MU101 from indica cultivar M804 was obtained in the progeny after treatment from 60Co γ-rays,and the morphology and cytology of MU101 were investigated and analyzed.The results showed that MU101 was dwarf with,dark green leaves,compact plant type,strong growth vigor,and normal heading and tilling ability.Interestingly,the MU101 had two less internodes than its wild type,and internode length was not could be applicable.Therefore,MU101 can be used as a special category of material,with further study value and application in breeding.Moreover,the research laid a basis for cloning the dwarf gene,studying the genetic mechanism and breeding the variety with an ideal plant type with marker-assisted selection.
