SUMMARY
The screening for water stress of fifty five CIMMYT maize genotypes was carried out to estimate the genetic variability and correlation at Agriculture Research Farm, Institute of Agriculture Science, BHU, Varanasi. The experiment was conducted in an alpha lattice design with two replication and phenotypic data were analyzed using seven traits. Analysis of variance revealed significant differences among the genotypes for all the parameters studied. The maize hybrids (ZH15506, ZH17506, ZH17229 and ZH17496) showed highest value for grain yield per plant. Yield per plant was increased with germination percentage, plant height at seedling and chlorophyll content. If the selection for a water logging tolerant genotype is made for any of these component traits, the improvement in yield per plant could be achieved.
Key words: Maize, Genetic Variability and Water stress and correlation
