利用荧光原位杂交和染色体 C-分带技术对普通小麦 -华山新麦草的异代换系进行了研究 .荧光原位杂交结果显示 :异代换系 H92 1- 6 - 12和 H92 4 - 3- 4均含有 2条华山新麦草的染色体 .对这 2个材料和华山新麦草进行染色体 C-分带带型比较 ,结果认为 :H92 1- 6 - 12可能是普通小麦 -华山新麦草的 5 A / N5h 代换系 ,H92 4 - 3- 4可能是 3D/ N4 h代换系 .
The result of fluorescence in situ hybridization (FISH) and chromosome C-banding showed that the isogenic lines of H92 1- 6 - 12 and H92 4 -3 - 4 all contained two chromosomes of P. huashanica.The chromosome C-banding patterns of these two materials were compared with that of P. huashanica and the results showed that H92 1- 6-12 could be 5 A / N5h substitution lines, H92 4 - 3- 4 may be 3D / N4h substitution lines.
