Abstract:
Executive Summary
The research work was conducted to find out okra (Abelmoschus esculentus L.) genotypes
against salinity stress in net house, Department of Genetics and Plant Breeding, Sher-eBangla
Agricultural University, Dhaka during the period of July 2022 to June 2023. This
study was conducted with eight okra varieties such as special Dherosh Green Super (V
),
Dherosh Sobuj Sathi (V
2
), Hira (V
3
), Dherosh BARI-1 (V
4
), Iron-40 Dherosh (V
), OK 285
(V
6
), Okra Soma (V
7
) and Nice Green (V
8
). Four salinity treatments viz. T
(3
dS/m), T
2
(6 dS/m) and T
(9 dS/m) were applied to the varieties. Salinity treatment affected
almost all traits of okra significantly. The tallest plant (77.25 cm) was found from V
3
whereas the shortest plant (45.79 cm) was found from V
. The interaction effect of
genotypes and salinity showed that the tallest plant (104.83 cm) was found from T
whereas the shortest plant (35 cm) was found from T

. The maximum fruit weight per pod
was found in V
(14.33 g) whereas the minimum fruit weight per pod (9.67 g) was found in
V

. The maximum fruit weight per pod (20.0 g) was found in T

and T
whereas the
minimum fruit weight per pod (6.67 g) was found in T

and T

V
. The maximum yield per
plant (126 g) was found in V
8
which was statistically similar with V
7
(112 g) whereas the
minimum yield per plant (54.00 g) was found in V
4.

From the research findings, V
(Ok 285
okra), V
(Nice Green) suggested at mild to moderate saline prone area because it performed
well under T

and T
3
treatment and V
2
(Dherosh Sobuj Sathi) and V
(Iron-40 Dherosh)
could be suggested for moderate saline prone areas on the basis of maximum fruit weight per
pod. Salinity stress adversely affects the physiology of okra at all stages of growth and
development. Observation of morpho-physiological characters played important role for the
selection of suitable genotype for future breeding purpose.
