Present investigation was planned to screen thirty maize landraces for root traits in relation to drought tolerance. Drought stress is one of the most important abiotic stress which reduces growth, development and yield of the plants. Developing maize cultivars that can perform well in drought and other abiotic stresses is an important goal throughout the world. Rooting depth was highest in SRG 9 (47 cm) and lowest in SRG 5 (14 cm) under drought condition. Root volume was highest in SRG9, SRG 10, SRG 12, SRG 19 and SRG 26 while lowest in SRG5 under drought conditions. The relative proportion of root biomass allocation to the top and bottom zones reveals that highest proportion of roots at bottom under drought was for SRG 21 (5 g) while as lowest for SRG 21 (0.2g). Similarly root biomass in top portion was highest under drought for SRG 21 (9 g) and lowest in SRG 7 (1.1 g).
