%X Salinity reduces germination, delays emergence, and inhibits seedling growth of linseed (Linum usitatissimum L.) while some varieties are less affected by salinity than others. In this study, we aimed to determine the effects of NaCl levels (0, 5, 10, 20 and 30 dS m-1) on germination and seedling growth of 10 linseed genotypes (lines 87, 89, 104, 114, 193, 194, 209, 215, C-90 and cv. San-85) and to classify the genotypes for salinity tolerance using germination and seedling characteristics. Germination percentage, mean germination time, root and shoot length, seedling fresh and dry weight, Na+ content and Na:K ratio of seedlings were investigated. Classification of linseed genotypes for salinity tolerance was done according to (i) combination of Principal Component and Cluster Analysis, (ii) Na+ content, and (iii) Na:K ratio of seedling. The results showed that the highest values were obtained from lines 193, 194 and 215 except for mean germination time, while germination percentage was not adversely influenced by NaCl up to 20 dS m-1. Seedling growth was inhibited at 20 dS m-1 although genotypes exhibited varying responses. Na+ content was enhanced by NaCl, but seedling from lines 194, 193 and 215 had the lowest Na+ content at all NaCl levels. Cluster analysis performed by multiple parameters revealed three groups for salinity tolerance. It was concluded that lines 193, 194, and 215 were tolerant, lines 87, 209, C-90, and cv. Sari-85 were moderately tolerant and lines 89, 104, and 114 were salt-sensitive genotypes. Classification of genotypes for Na+ content and Na:K ratio showed similar result for tolerant genotypes while different genotypes for sensitive group were detected. La salinidad reduce germinaci車n, retrasa emergencia, e inhibe el crecimiento de pl芍ntulas de lino (Linum usitatissimum L.) mientras algunas variedades son menos afectadas por la salinidad que otras. El objetivo de este estudio fue determinar los efectos de niveles de NaCl (0, 5, 10, 20 and 30 dS m-1) en germinaci車n y crecimiento de pl芍ntulas de 10 genotipos de lino (l赤neas 87, 89, 104, 114, 193, 194, 209, 215, C-90 y cv. Sari-85) y clasificar los genotipos por tolerancia a salinidad usando caracter赤sticas de germinaci車n y de pl芍ntulas. Se evaluaron porcentaje de germinaci車n, tiempo medio de germinaci車n, longitud de ra赤ces y brotes, peso fresco y seco de pl芍ntulas, contenido de Na+ y relaci車n Na:K de las pl芍ntulas. La clasificaci車n de los genotipos de lino por tolerancia a salinidad se hizo de acuerdo a (i) combinaci車n de An芍lisis de Cluster y Componentes Principales, (ii) contenid
