The present study was carried out during 2022 to 2024 at Punjab Agricultural University, Ludhiana, Punjab to determine the influence of salinity levels of 0, 2, 4 and 6 dS/m on morphological and yield characteristics of 16 highly tolerant pepper (Capsicum annuum L.) genotypes initially selected by testing 100 genotypes at nursery stage. The experiment was conducted using a split plot design (SPD) with salinity treatments as main factor and genotypes as sub factor. Artificial saline conditions in pot were created using NaCl, MgSO4 and CaCl2 in the ratio 2:1:1. The findings revealed that salinity caused a significant decrease in plant height, internode length, branch number, root weight, fruit characteristics, fruit number and yield. Additionally, it also delayed the onset of flowering in all genotypes. When compared to other genotypes, genotypes PAU-212, YL-581 and SL-474 performed superior in all parameters when exposed to salt stress. Maximum yield at highest salinity level was exhibited by PAU-212 (519.8 g/plant) and was followed by YL-581 (511.7 g/plant). In terms of percent decrease in yield at higher salinity levels in comparison to control conditions was minimum in GC-222, with only 16.9% reduction, followed by YL-581 (18.4%) and SL-474 (22.8%). Thus, it can be concluded that PAU-212, YL-581 and SL-474 proved to be the most suitable genotypes for salt tolerance in pot conditions and could be considered for future studies and cultivation in salt affected regions.
