3.3. Association mapping
There was a large variance in seedling response to salt stress (Fig. 4, Table S1). The controls responded as expected. The SES scores for Nona Bokra and Binadhan-8 were 3.0 and 3.7 (tolerant), whereas that for Binadhan-7 was 8.3 indicative of low tolerance. Among all 96 accessions 12 were tolerant (1 < score ≤ 3), 30 moderately tolerant (3 < score ≤ 5), 18 sensitive (5 < score ≤ 7), and 36 highly sensitive (7 < score ≤ 9). None was highly tolerant (score = 1).
