Varieties Rai-5, Shambal
and Daulat of Brassica juncea and varieties Barisarisa-7 and
Barisarisa-8 of Brassica napus were tested for yield and component
characters under different levels of soil salinity. The variations due
to salinity levels, varieties and variety-salinity (interaction) were
significant for different characters. The variable degrees of increase
and decrease of regression coefficient estimates (curve estimation)
indicated the performance as influenced by different salinity levels.
The performance of the variety Barisarisa-7 in plant height and days
to first flowering is the best followed by Barisarisa-8 and Daulat.
Barisarisa-8 showed the best performance in days to maturity followed
by Barisarisa-7 and Shambal. Shambal followed by Daulat and Barisarisa-7was
performed incase of number of siliqua per plant. Daulat performed better
than others incase of seed per plant and seed yield per plant followed
by Rai-5. Considering all the characters the most tolerance ability
was found in Daulat under B. juncea and Barisarisa-7 under B.
napus which were followed by Barisarisa-8 of B. napus against
different levels of salinity.
