In order to Evaluation of yield and its related traits in Wheat cultivars treated with fluorescent Pseudomonads under salt stress , experiment desing was a split plot design with three repetitions in the year of 1394-95 in the research greenhouse at the Faculty of agriculture and natural resources, Persian Gulf University, Bushehr was implemented. Salinity stress was considered as a major factor in four levels (0, 50, 100 and 150 mm NaCl), wheat cultivars (Kuhdasht, dehdasht, Karim and Bam) as a first sub-plots and four strains of fluorescens pseudomonads (WKZ1-93، 2-79، WB1-7 and WBO-3) along with a control treatment (no bacteria) were considered as the second subplots.. The results analysis of variance of the experimental data determined there was a significant difference between salinity levels in all studied traits except spike weight and spike number and the interaction of salinity × variety in all measured traits except for peduncle length and other simple and cross effects were significantly different in each trait. Results of correlation coefficient showed the highest correlation between grain yield and peduncle length (r = 0.58**).In stepwise regression, peduncle length, spike length, grain weight, plant height and number of grains per spike were entered the model and confirmed the 51% of the total yield variations. Path analysis for grain yield revealed a direct and positive impact of peduncle length, spike length and 1000-grain weight and indirect effect of 1000-grain weight through peduncle length and peduncle length through spike length on yield.
