Abstract: In the present research eighty barley cultivars from South Tunisia were evaluated. The markers used are: leaf number, length and width at vegetative and reproductive stage, tiller number and grain number per spike at maturity. Analyses of histogram`s showed that salinity had significant effect on all the growth parameters at different growth stages. However, vegetative stage was affected more adversely than reproductive and grain filling stage. At vegetative stage, the average reduction of the number of leaf is 38%, wile this reduction don`t exceed 27% at reproductive stage. The salinity induce also an important reduction in tiller number 24%. At reproductive stage, the results showed that, average length was affected more by salinity 30% than the tiller number 24%, width of leaves 27% and leaf number 27%. At maturity, number of grain was least affected by salinity. The reduction is 4.7% compared with the control treatment. Thus, at the vegetative stage, Cultivars Ksar Oun, Elbagbag 1 and 2, Amdi, Oued el Kil (Tataouine) were ranked at the more salt tolerant. At reproductive stage the result show that cultivars Mgitt, El Kir, Tlalite, Ksar Ouled Boubaker and El Ferch (Tataouine) were ranked as the most tolerant genotypes.
