a UHML, fiber upper-half mean length;
b UI, uniformity index;
c MIC, micronaire value;
d EL, elongation percentage;
e ST, fiber strength;
f CV, coefficient of variation.
* and ** indicate significant differences at P#0.05 and 0.01 probability levels, respectively. ns, not significant (P≤0.05). Values followed by a different letter between salinity levels are significantly different at P = 0.05 probability level. Each value represents the mean of three replications. LS: low soil-salinity, MS: medium soil-salinity, and HS: high soil-salinity.
