Values are means (± SD) of three experiments. Each experiment has three replicates. Means followed by different letters within a column under each treatment are significantly different at 5% probability level according to Tukey’s Test. TMS 0040-IITA-TMS-IBA010040 (drought sensitive), TMS 581-IITA-TMS-IBA980581 (drought tolerant)
