In the rabi season of 2019-2020, an experiment in three distributed replicas at three different locations: Satkhira (AEZ-11), Koyra (AEZ-13) and Bagerhat (AEZ-11) were conducted in the farmer’s field of Khulna division to select suitable soil salinity resistant varieties. Fourteen exotic potato varieties (Solanum tuberosum) have been characterized under saline stress conditions of the coastal areas of Bangladesh. Tuber skin color BARI Alu-35, 37, 40, 41, 73 and 81 are white to light yellow in color and BARI Alu-36, 72, 78 and 79 were red. The highest emergence (%) at 30 DAP was found in BARI Alu-72 along with highest foliage coverage (%) at 60 DAP. Moreover, BARI Alu-72 produced number of stem hill-1, number of tuber plant-1, weight of tuber plant-1, weight of fresh plant (kg), dry matter tuber and tuber yield. Varietal yields ranged from 20.98 to 29.75 t ha-1. Among the varieties, BARI Alu-72 yielded highest (29.75 t ha-1) followed by BARI Alu-73 (28.01 t ha-1) and BARI Alu-79 (27.66 t ha-1). Since BARI Alu-72 produced comparatively higher yield form other varieties, it could be considered suitable for costal region. If it suits into their cropping pattern, the variety may be a good option for farmers by increasing cropping intensity, benefit financially and meet their nutritional demands.
Key words: Costal area, dry matter, potato, soil salinity, variety, yields performance.
