Abstract
A laboratory
experiment was conducted at Plant Physiology Division, Bangladesh Agricultural
Research Institute (BARI) during rabi season of 2013-2014 to evaluate the
response of 36 wheat genotypes to different levels of salinity and to find out
the salt tolerant genotype(s) for saline areas. The treatments consisted of
thirty six wheat genotypes and four levels of salinity (0, 5, 10 and 15 dS m-1)
in complete randomized design (CRD) with three replications. The plant growth
media was used in Hoagland solution with pH 6.0. Distilled water was used as a
control (0 dS m-1) treatment. The results showed that germination
percentage, seedling root and shoot dry weight and vigour index were found to
be affected by different levels of salinity. Among the tested genotypes of
wheat, BWSN E-15, PYT E-14 (BAW-1193), CVD E-5
(BAW-1135), CVD E-9 (BAW-1151), CVD E-10 (BAW-1157), CVD E-11(BAW-1161) , CVD
E-12 (BAW-1163) and PYT E-15 showed better performance up to 10 dS m-1
as evaluated on the basis of germination percentage, seedling growth, seedling
dry weight and vigour index.
