Abstract
Salinity is one of the most important factors that limit crop production in
some regions of the world. Knowledge of the interrelationships between yield
and its components will improve the efficiency of breeding programs
especially under saline conditions through appropriate selection criteria.
This study demonstrated that GT biplot was an excellent tool for visual
evaluation of superior genotypes, traits and grouping of them with other
statistical techniques. The study was conducted under both saline and
non-saline conditions in field based on randomized complete block design with
three replications. Electrical conductivity of irrigation water were 2 and 10
dS.m-1 in non-saline and saline conditions, respectively. The obtained data
were analyzed using a genotype trait (GT) biplot method based on site
regression model. The biplot vector view indicate that there was a strong
positive association between PH and BY with seed yield in both non-saline and
saline conditions. It seems that PH and BY traits can be used as selection
criterion for improving of seed yield in wheat breeding programs, especially
under stress conditions in the field. Also among 41 studied genotypes,
genotype 32 had good characteristics regarding high seed yield and salt
tolerance.
