Abstract	The objective of this work was to evaluate the degree of tolerance and sensibility to the salinity of genoty,pes of rice (Oryza sativa L.) during the vegetative phase of the plant. The experiment was lead under greenhouse conditions at IPA (Empresa Pernambucana de Pesquisa Agropecuaria), in 1996. Twelve genotypes of rice had been evaluated, being ten tolerant and two sensible ones to salinity in the vegetative development stadium. The randomized blocks design were performed into three repetitions of factorials arrangements (twelve genotypes x four levels of NaCl). Results had evidenced variability existence among the genotypes of rice, in the specific population, for tolerance and sensitivity to the salinity. Samples PR492, PR504, CNA8250, CNA8262 and CNA8267 can be considered tolerant to salinity, while the genotypes CNA8270, CNA8258, CNA8269, PR475 and PR477 are sensible to salinity of soil during the vegetative phase.
