Abstract
The root systems of 8 sorghum cultivars were studied after failure of rains during the wet season of 1970. Cv. IS 1183, 59/138, 59/153, and IS 1137 were not adversely affected by 3 weeks of drought, but IS 9673, IS 9183, B 36-1 and IS 9357 wilted. At 40 days the roots of the resistant cultivars had penetrated deeper into the soil than the susceptible cultivars. The latter were more extensive in lateral root development, and at harvest had begun to show peripheral disintegration. Number and weight of primary and secondary roots and root:shoot ratios were higher in the resistant cultivars than in the susceptible ones. Ear emergence was significantly correlated with root weight and maturity.
