Performance of Tomato (Solanum lycopersicum L.) Genotypes Based on Agro-morphogenic Traits under Drought Condition

A pot experiment was conducted in the net house of the Department of Genetics and Plant Breeding, Sher-e-Bangla Agricultural University, Dhaka-1207, during November 2013 to March 2014 to observe the performances of fifteen tomato genotypes under three different drought treatments. Two factorial experiments included fifteen tomato genotypes viz. G1 (BD-7759), G2 (BD-7292), G3 (BD-7760), G4 (BD-7258), G5 (BD-7762), G6 (BD-7761), G7 (BD-7289), G8 (BD-7291), G9 (BD-7301), G10 (BARI Tomato-11), G11 (BARI Tomato-9), G12 (BARI Tomato-8), G13 (BARI Tomato-7), G14 (BARI Tomato-3) and G15 (BARI Tomato-2) and three drought treatments, T1 (Control), T2 (30 days withholding of water) and T3 (45 days withholding of water) were outlined in completely randomized design (CRD) with three replications. The results showed that both, the different tomato genotypes and drought treatments had significant influence independently and also in interaction on agro-morphogenic traits of the tomato plant. Almost all traits responded negatively as the drought level increased except days to first flowering, maturity. Considering the yield and yield contributing characters, genotype G4, G5 and G6 showed tolerance at moderate drought stress and G6, G7 and G13 showed tolerance at prolonged and severe drought stress. These genotypes could be recommended to the farmers for cultivation in the drought-prone areas of Bangladesh and also could be used in future hybridization or other gene transfer programs.
