Abstract
Thirty
field pea genotypes were tested against varying levels of salinity (0, 5, 10
and 15 dS m-1) in Hoagland solution under laboratory condition at
Plant Physiology Division, BARI during 2013-2014 to find out the salt tolerant
genotypes at germination and seedling stages.
The study was conducted in completely randomized design (CRD) with three
replications. Distilled water was used as control (0 dS m-1)
treatment. Germination percentage,
seedling root and shoot length, root and shoot dry weight and vigor index were
found to be affected by different levels of salinity. The genotypes BD-4159,
BD-4150, BD-4163, BD-4161, BD-4152, BD-4160, BD-4167 and BD-4151 showed better
performance up to 10 dS m-1 as evaluated on the basis of
germination percentage, seedling growth and vigour index.
