reduced between control and 100 mM NaCl (Table 3.4.3). Data regarding oil contents 
clearly indicate the wider differentiation between salt sensitive and tolerant genotypes in 
linseed. Salt tolerant genotypes expressed clear difference in their percent oil contents 
even at control where no salt (NaCl) was added in soil. The maximum seed oil contents
was measured in NO-303 (35.80%) followed by 637-72 (34.90%) while the minimum 
seed oil contents were noted in S-907 (26.60%) and C-99-3-115 (27.80%). Seed oil 
contents of salt tolerant genotypes NO-303 (35.80%) and 637-72 (34.90%) were 
statistically significant from that of salt sensitive genotypes C-99-3-115 (27.80%) and 
S-907 (26.60%) in control treatment. Genotypes showed sharp decrease in seed oil 
contents
with increasing levels of salinity, but salt tolerant genotypes contained 
relatively higher percent oil contents than salt sensitive genotypes of linseed. For 
example, it was noted that salt tolerant genotypes NO-303 contained 27-58% oil 
contents and 637-72 contained 24.46% oil contents in their seeds which was higher than 
that contained in salt sensitive genotypes C-99-3-115 (21.15%) and S-907 (20.68%) 
(Table 3.4.3).
