SUMMARY
Salinity stress is one of the major abiotic stresses that adversely affects morpho-physological and growth yield traits. In the present investigation, five Kodo millet varieties were tested for salinity stress tolerance at seedling stage. Shoot length, shoot, and root fresh weight, shoot, root dry and weight, total shoot and root water content were affected by salinity stress. The maximum root to shoot ratio was observed in TNAU 86. The relative germination rate and relative salt injury data for the five Kodo millet varieties at 50, 100, and 200 mM showed that TNAU 86 (96, 83 and 57) and QK- 390-25 (95, 95 and 52) are the resistant varieties to salinity stress. Among the five Kodo millet varieties TNAU 86 followed by QK-390-25 performed well when compared to the other varieties at all the salinity treatments.
