Abstract: Improving different Lebanese genotypes is based on analyzing local genotypes and estimating genetic dissimilarity between them. As a result this study aim to detect the salinity tolerant genotypes based on two culture systems, the in situ sand based system and the stagnant nutrient solution system and assessing the phylogenetic relationships among the five different genotypes under study, based on 16 SSR loci. The study illustrated the tolerance of the genotype Tairaya at the germination stage while its sensitivity was emphasized at later stages of development. Moreover, Kamed El Louz, Aaitit and Bebnine were considered as tolerant at later stages as they possessed the lowest percentage of reduction of the parameters under study in the two culture systems. Eventually, the genotypes didn’t reflect the same tolerance pattern although the genetic differentiation between them was not significant.
