Abstract: Solanaceous family are the most cultivated plants across the world, where tomato is one of amenable Solanaceous model crop plant extensively grown because of its nutritive value. The plants are sessile in nature therefore they experiences many adverse environmental conditions. Due to some erratic environmental conditions, situation become harsh and leads to abiotic and biotic stresses. To overcome this undesired condition, plants have adapted several mechanisms at cellular level, molecular and physiological and also at whole plant level. Amongst them, root characters play a major role during stress condition. Under these premises, 100 tomato accessions were evaluated using augmented block design in root structure under normal conditions to study genetic variability for root characters such as root length (cm), root volume (cm3) and root dry weight (g). There is a large variation among the accessions for all the root traits and also for ancillary traits like shoots length, SPAD, specific leaf area (cm2), leaf dry weight (g), stem dry weight (g), shoot dry weight (g). Based on root dry weight contrast lines were identified and can be used for crop improvement approach.
