Abstract

In order to selecting of salinity tolerant variety (ies) of Canola in saline conditions and determination of the salinity response, 60 canola varieties were evaluated during two years. In the first year we reduced the number of varieties in the way of logic reduction by Augment experiment. Total of 41genotypes were eliminated and 19 of them were evaluated in the second year. So, the salinity response of selected varieties was investigated in this paper. The experiment was conducted as a split plot design with randomized complete block design in three replications. The salinity of irrigated waters (2 and 11 dS/m) were as main plot and varieties were placed in subplots. Based on the results of the experiment, the average of grain yield was 2419.8 and 1456.5 kg.ha-1 in high and low salinity conditions respectively, so that there was significant differences between them at 1% level of probability. In the low saline condition, the varieties of Hyola401, Opera, Option500, Sarigol, Hyola420, SYN and Option501 were produced higher grain yield rather than others. Also in the high saline condition, the varieties of Hyola420, Hyola401, Option501, RGS, Mozart, SYN, and Rindow had higher grain yield rather than others. Evaluated of the grain yield in both low and high saline condition showed that the varieties of Hyola420, Hyola401, Option501, Opera, RGS, Option500, Mozart, SYN, and Sarigol were produced highest average yields of 2871.4, 2814.4, 2400.7, 2394.7, 2347.4, 2338.5, 2295.4, 2288.5 and 2178.8 kg.ha-1, respectively.
