Exposing maize plants to water deficit stress (WDS) causes a huge reduction in the
grain yield. Current breeding programs should pay great attention to develop hybrid corn of
high tolerance to WDS. Eight inbred lines with obvious diversity in their adaptive traits to
WDS were used in the present investigation as parents of diallel crosses (without
reciprocals) to assess the genetic diversity of the parental inbreds and its relationship with
heterosis, estimate general (GCA) and specific (SCA) combining ability, type of gene
action, heritability and genetic advance of these traits. The evaluation of 8 inbreds and their
28 F1 hybrids was carried out in 2020 and 2021 seasons. A split plot design in randomized
complete blocks arrangement with 3 replications was used. Main plots were devoted to
watering treatments, namely well watering (WW) and (WDS),
