Abstract:

A total of thirty three genotypes of tomato including three checks were analysed in an experiment to determine their tolerance and susceptible levels against drought stress. Four different concentrations of PEG 6000 viz., 4%, 8%, 12% and 16% were used along with control. The genotypic differences investigated were found significant for all the seedling parameters studied. With increasing concentration of PEG growth parameters of seedlings like germination percentage, germination rate, root length, shoot length, root dry weight and shoot dry weight decreased proportionately. Among the parents EC-620428, Arka Saurabh, EC-620360, EC-620427 and EC-620557 exhibited superior performance and among the crosses evaluated EC-620428 × Arka Saurabh, EC-620360 × Arka Saurabh, EC-620427 × EC-620557 responded superior performance compared to other crosses. These genotypes may be used as positive/tolerant controls in future studies. However, the internal physiological investigation is needed for assessing their variable response.
