Germination Ability of Different Field Pea (Pisum sativum L.) Genotypes Under Salinity Stress

A laboratory experiment was conducted at the Pulses Research Sub-station, Bangladesh Agricultural Research Institute (BARI), during October to December 2019 to examine the establishment of field pea seedling under the effect of saline condition. The experimental was arranged in a completely randomized design (CRD) with three replications. The experiment induced two factors, first factors included 34 different field pea cultivars and second factor included four (4) salt concentration of NaCl including control (0 dS m-1), 4 dS m-1, 8 dS m-1 and 12 dS m-1. Experimental result revealed that BARI Motor 1 exhibited the highest germination (98.75%) in control situation (0 dS m-1) and lowest germination percentage was recorded in Natore local 1 (68.75%). BARI Motor 3 gave the highest mean daily germination (27.93%) and seed germination 1.68 seed day-1 under control. The lowest mean daily germination was observed in BD-6944 (17.42%) genotype and seed germination was found in Natore local 1 (0.95 seed day-1). The maximum germination value was observed in BARI Motor 1 (19.53) genotype and germination vigor index in BD-9047 (16.35 mg) genotype. On the other hand, minimum germination value was observed in Jhikorgasha local (10.0) and minimum germination vigor index was found in Natore local 1 (5.10) and BARI Motorsuti 1 (3.64 mg) in control condition. In this study, it was observed that an increase in salinity stress significantly decreased all the germination parameters studied.
