Lines which were 2n=21"+1" and one line which was 2n=20"+2", one line which was 2n=43. The salt-resistance addition line Line15 was confirmed as a Disomic alien addition line by C-banding, SSR, FISH methods, and the two alien addition chromosomes had close correlation with the long arm of the second homoeologous group, the centromere region of the third homoeologous group and the short arm of the seventh homoeologous group. We also confirmed the particular C-banding type of the alien addition chromosomes by C-banding following FISH method. The drought-resistance addition line Line17 was found also as a Disomic alien addition line by SSR and FISH detection. The alien addition chromosomes had close correlation with the short arm of the second homoeologous group.

对导入赖草优质耐盐基因的株系Line15进行了C-分带、荧光原位杂交、SSR相结合的鉴定，确认Line15是一个二体异附加系，附加的一对染色体与小麦的第二同源群长臂、第三同源群着丝粒和第七同源群短臂密切相关，并确定了Line15的外源染色体C-分带特征带型，为目后鉴定Line15附加系的真伪提供了简便快捷的途径；对抗旱附加系Line17进行了荧光原位杂交和SSR检测，得出Line17也是一个二体异附加系，外源染色体与小麦的第四同源群短臂密切相关。
