Assessment of salinity tolerance capacity on physio-morphological and yield attributes of promising tomato genotypes

抄録

An experiment on tomato was conducted at the Net House Premises of Soil Science Division, Bangladesh Agricultural Research Institute; Gazipur during the winter season from Nov.2013 to Feb. 2014. The major objective of the study was to assess the salinity tolerance ability of promising tomato genotypes in order to identifying the salt tolerant ones. Six levels (1.14, 4, 6, 8, 10 and 12 dS m^-1) of irrigation water salinity were imposed to three genotypes of tomato V₁ (BARI Hybrid Tomato 4), V₂ (BARI Hybrid Tomato 5) and V₃ (BARI Hybrid Tomato 8). The pot experiment was set up in a Completely Randomized Design with 3 replications. Salinity was imposed as per treatments at the pre-flowering stage two times at 45 and 55 DAS. The variety V₃ gave the highest fruit yield (1.62 kg/ plant equivalent to 55.25 t/ ha) along with better morphological characters. Considering all studied traits and yield potentiality, BARI hybrid tomato 8 can be regarded as the salt tolerant genotypes.
