3.4.3.3 Effect of salt stress on number of seeds pod
 -1
 
 
In linseed genotypes, seed production was badly affected by salt stress and 
number of seeds pod
-1
of all the genotypes were considerably affected by the 
application of increased levels of salinity. Thus number of seeds pod
-1 
were 
significantly reduced between control and 100 mM NaCl (Table 3.4.2) while at 200 
mM NaCl, genotypes were not able to produce seed in pods. There was no 
considerable variations among linseed genotypes regarding number of seeds pod
-1
and 
the maximum number of seeds pod
-1 
were counted in NO-303 (9.67) followed by 
637-72 (8.67), however, S-907 produced least number of seeds pod
-1
(7.67) as 
compared to other salt sensitive genotype C-99-3-115 at normal (non saline) soil. 
Number of seeds pod
-1
of salt tolerant genotypes NO-303 (7.33) and 637-72 (6.33) 
was statistically significant from salt sensitive genotypes C-99-3-115 and S-907 (4.67) 
at 100 mM NaCl. Although, salt sensitive genotypes produced equal number of seeds 
pod
-1
but on the basis of percent of control genotype S-907 produced more seeds 
(61%) as compared to C-99-3-115 (56%) at 10 10dS m
-1
. On the other hand, salt 
tolerant genotype NO-303 produced even higher number of seed pod
-1
(76% of 
respective control) than salt sensitive genotypes followed by 637 -72 (73% of 
respective control) at same salinity level..
3.4.3.4 Effect of salt stress on seed yield plant

Soil salinity affects seed yield of many crops and this affect was very drastic in 
linseed genotypes, although salt tolerant genotypes showed relatively higher seed 
yield plant

as compared to salt sensitive genotypes. Statistically, the interaction
