This study is part of a research project on the varietal tolerance with salinity of soil jointly managed by MAIB-Italy, INRA-France and ICARDA-Syria. Two experiences were carried out on the common wheat (Triticum aestivum). The study of germination showed that the Cham-8 variety is more salt tolerant than Sakha-8. The second on a lysimètre set-up is aimed at analysing the effect of soil salinity on water status, the growth, the productivity and water efficiency of these varieties, considered by the preliminary observations of ICARDA, as respectively tolerant and sensitive to salinity. The lysimeter experience shows that under no-saline conditions, these varieties present the same water behaviour and biomass. In saline soil these varieties reduce their yields to the same extent. The reason of this reduction is in both cases related to the number of ears per seedling. The observed results indicate that the tolerance of these varieties is similar.
