Salinity response parameters of the genotypes, a is the slope of decrease in the process rate at the inflection point and b is the critical value of salinity for 50% of loss of the process rate. Values were derived from Radanielson et al. (2017) from greenhouse experiments and calibrated to the field crop responses.
