Abstract:
The research was carried out during the two seasons (2019-2018) and (2020-2019) in Tartous Governorate, with the aim Study the relationship between grain yield and some drought tolerance indicators for several types of soft wheat strains : ACSAD 1256, DOMA 58847, DOMA 58585, DOMA64453, ACSAD 1149 and two approved cultivars. DOMA 2 and DOMA 4 under protected conditions. it was found that there were Significant differences between the two seasons in grain yield under control conditions, stress and drought tolerance indicators (STI), (MSTI), (MP), The correlations of the stress tolerance index showed a strong positive significant correlation with the modified drought tolerance index( MSTI), and mean geometric productivity MP and the correlations showed the correlation of the stress tolerance index STI, a strong positive significant correlation with the modified drought tolerance index MSTI, and the mean geometric productivity MP at both treatments. The best parameters that were positively correlated with grain yield under control and stress conditions are indicators: Drought Tolerance Index STI, mean geometric productivity MP
Keywords: drought stress, grain yield, indicators of drought, Triticum aestivum
