There is need to evaluate maize inbred lines, which are resistant to drought conditions. Ten maize inbred lines namely MO-17, DK-656, lZI-7103, SYP-31, AYP-17, H-93, B-73, A-6660, IZI-4001 and KLI-2301 were exposed to water stress in drought chamber. Genotypic and phenotypic correlation coefficients of various plant morpho-physiological traits with grain yield were ascertained. Survival rate treat-II, root-shoot ratio, stomatal frequency and photosynthetically active rations showed significant correlation at genotypic level with grain yield. The study emphasized that these morpho-physiological traits have underlying genetic basis. Once these basis are understood precisely, breeders will be able to tailor maize varieties with better yield potential.]]>Ali, A.,1994Aestivum spp.]]>1994Dai, J.Y., W.L. Gu, X.Y. Shen, B. Zheng, H.
