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.
