Excess Soil Moisture (ESM) stress caused by temporary water logging is a major limiting factor for maize production and productivity in Asian countries. In this context, the present investigation was carried out to study genetic variability, character association and path analysis in 35 maize hybrids under excessive soil moisture condition. Analysis of variance revealed highly significant differences among the genotypes for all the characters. High heritability with high genetic advance was observed in senescence percent(after excess water stress), difference in senescence, number of kernels per row, number of kernels per cob and grain yield, indicating the preponderance of additive gene action in controlling the traits. Yield was positively and significantly correlated with plant height, ear height, length of cob, girth of cob, number of kernel rows per cob, number of kernels per row, number of kernels per cob, 100 kernel weight and shelling %. Among these, number of kernels per row, days to 50% tasseling, 100 kernel weight and number of kernels per cob had direct positive effect on grain yield at genotypic level. Senescence percent had shown highest positive indirect effect via number of kernels per row on grain yield. This happens to be the case in water logging tolerant hybrids.
