摘　　要：用改良的C-分带技术鉴定南京农业大学细胞遗传研究室获得的普通小麦的簇毛麦V_2、V_3、V_4、V_6、V_7染色体异附加系和V_2、V_5异代换系,得到与N-分带和染色体配对分析一致的结果,并且由于C-分带可同时鉴别小麦全部21对染色体,鉴定出V_2异代换系中被代换掉的小麦染色体为1A。Providing more diagnostic hands of both wheat and H. villosa chromosomes, an improved C-banding technique facilitated the direct identification of H. villosa chromosomes in 5 wheat alien addition lines of H. villosa chromosomes V2, V3, V4, V6, V7 and 2 alien substitution lines of V2, V3. Profiting from the complete recognition of wheat chromosomes by this technique, the substituted wheat chromosome in substitution line V2 was identified as 1A.
