摘 要 ：采用基因组原位杂交(GISH)检测和染色体组成分析方法,对大穗多花小麦新种质4844后代的15个株系进行遗传分析。结果发现,4844-12是1个稳定的异附加系,4844-2和4844-8是稳定的异代换系;对异代换系进行SSR分析表明,代换系中小麦的6D染色体被1对P染色体代换,说明这对冰草染色体与小麦6D染色体有部分同源关系,由此确定4844中的冰草染色体为6P;同时筛选出冰草6P染色体的4个SSR标记。

Abstract:GISH and SSR were adopted to genetically analyze 15 offspring plants (lines) of the new wheat germplasm 4844 with large and multiflorous spikes.It was found that 4844-12 was a stable alien additional line and 4844-2 and 4844-8 were stable alien substituti
