Two black gram varieties LBG-806 (resistant variety) and LBG-823 (sensitive variety) were selected (as per TIR protocol) for identification of thermotolerance. Among three temperature treatments (control, induced, non-induced) as per TIR protocol, plants acclimatize for severe temperatures under induced treatment and then eventually able to survive even in the followed lethal temperature. In the estimation of proline content, thermo-tolerant variety (LBG-806) at 0th day, showed significant increase in content in induction treatment (38.28%) and significant decrease in non-induction treatment (70.18%), over control was observed. In thermo-sensitive variety (LBG-823) at 0th day, increased content in induction treatment (37.50%) and decreased content in non-induction treatment (69.67%) over control was significant at P≤0.01. Proline content was appeared high especially in induction treatment of thermo-tolerant variety (LBG-806) explained its cellular and acquired thermo-tolerance.
