Salinity stress is a major abiotic factor that affects crop output, and as pioneer in saline alkaline land, salt tolerance study of cotton particularly important. In our experiment, four salt-tolerance varieties with different indexes including CRI35 (65.04%), Kanghuanwei164 (56.19%), Zhong9807 (55.20%) CRI44 (50.50%), well salt-sensitive Hengmian3 (48.21%), GK50 (40.20%), Xinyan96-48 (34.90%), ZhongS9612 (24.80%) were used the materials. These materials divided into salt-tolerant group (ST) (SS). Illumina Cotton SNP 70K Chip was to detect varieties. SNPv (SNP variation same seedling pre- after- stress) screened; polymorphic SNPr related tolerance) obtained. Annotation analysis these SNPs showed (1) induction efficiency salinity on index different, which significantly higher than The obviously biased. (2) induced by may be methylation changes under stress. (3) influence plants affecting expression genes.
