Genotypes GL15A, G16V and MI16N showed better performance in drought conditions in the early drought stages of development (BBCH 09-10) (STI average varied from 2.1 to 3.9). the high sensitivity of drought conditionally, can be determined the genotypes Szegedi 1023 and AS17P (STI is from 2.9 to 4.6). It was found a specific variety reaction with regard to the effect of different sucrose concentration on seedling growth (cm) and fresh weight of seedlings (g) in the tested genotypes Sorghum vulgare var. In order to simulate the water deficit induced by osmotic stress, different concentrations (0.08% 0.16% 0.32% 0.64% 1.25% 2.5% 5.0% 7.5% 10.0% 12.5% 15.0% 17.5% and 20.0%) of water soluble sucrose were used in the study. technicum was determined under laboratory conditions at the Institute of Forage Crops, Pleven. Abstract: The effect of sucrose on the induction of water stress on germination and the initial development of five genotypes (varieties and local populations) Sorghum vulgare var.
