Characterization of Maize Hybrids (Zea mays L.) for Salt Tolerance at Seedling Stage

Salinity is the most atrocious environmental aspects restricting productivity of agricultural crops. To fulfill global increasing demand food, selection salt tolerant genotypes to get production from affected soils imperative. In present experiment, ten maize were evaluated against four salinity levels (control, 40 mM, 80 mM and 120 NaCl) using different agronomic physiological criteria. Significant variations observed in all morpho-physiological ionic attributes hybrids. Results depicts that hybrid 2225 exhibited tolerance show higher plant biomass, chlorophyll water contents, membrane stability along with K+/Na+ ratio. While 8711 had lower growth among hybrids considered as sensitive genotype. The results can be used a tool for provide better source breeders further assessment on saline lands.
