Abstract
The objectives of this investigation were to study salt effects on grain yield, its components and some agronomic & physiological traits of eleven bread wheat cultivars. These cultivars were grown in pots under greenhouse conditions, and subjected to four salinity levels (tap water (control), 3000, 6000 and 9000ppm), as dilutions of seawater. The experiment, in each year, was laid out in randomized complete block design and split-plot arrangement, with four replications. The results revealed that there were significant variations with all studied characters due to years(Y) (except for number of spikes /pot and 100-grains weight), Salinity levels (S), wheat cultivars (C), Y*S interaction (except for 100-grains weight), Y*S, S*C and three factor interaction Y*S*C. The data in indicated that the significantly highest grain yield was obtained at 3000ppm salinity level and that character decreased significantly with lower or higher salinity levels. Cultivar Debiera recorded the highest grain yield (12.65g) among all cultivars, which was not significantly different from Sakha 93 (11.88g), while Gemmiza 9 ranked the lowest (8.58g). Cultivars differed in their response to increased salinity levels. In general, all cultivars suffered reduction in grain yield increase in salinity level to 9000 ppm ranging from 16.8 to 62.5%. However, cultivars Giza 168, Giza 171 and Misr 2 recorded low reductions in the range from 16.8 to 32.0%, while cultivars Sakha 8 and Sakha 93 suffered intermediate reductions in the range from 32.0 to 47.3%. The highest reductions, in the range from 47.3 to 62.5%, were recorded for Sids 1, Sids 13, Gemmiza 9, Gemmiza 12, Nubaria 1 and Debiera cultivars. According to salinity susceptibility index, cultivars were categorized into three groups, high tolerance to 9000 ppm included Giza 168, Giza 171 and Misr 2 with SSI values ranging from 0.358 to 0.678. Cultivars that revealed intermediated tolerance included Sakha 8 and Sakha 93 with SSI values ranging from 0.678 to 0.998. Finally, the last tolerant (susceptible) Cultivars included Sids 1, Sids 13, Gemmiza 12, Gemmiza 9, Nubaria and Debiera with SSI values ranging from 0.998 to 1.32.
