Effects of salinity stress on seedling biomass, physiochemical properties, and grain yield in different breeding wheat genotypes

The salinity tolerance of 17 breeding wheat genotypes along with three local varieties was evaluated under control and stress (160 mM NaCl) conditions. At the seedling stage, several growth physiological traits were measured. Moreover, investigated assessed in terms grain yield across four saline regions during 2018–2019 cropping seasons. Salinity treatment significantly decreased root shoot dry weights (RDW SDW), photosynthesis rate (PN), stomatal conductance (GS), transpiration (TE), K+ content (SK), K+/Na+ (RKN), (SKN), root-to-shoot Na+ translocation (RTSN), (RTSK), but resulted increased (RN), (RK), (SN). results additive main effects multiplicative interaction analysis (AMMI) also indicated significant differences among test environments (E), (G), their (GEI). PCA-based biplot revealed that strongly correlated RKN RK. Furthermore, correlation PN, GS, TE strong positive had a RWC, MSI, RDW, SPAD index. Considering our results, RK identified as useful tools to screen salt at early-growth stage. According ranking patterns obtained by average sum ranks method (ASR) yield, we observed genotype number G5 considerable potential stage responded well soil farm; thus, this can be promoted for commercial production.
