The effect of adding different sugar concentrations of five treatments (T1, T2, T3, T4, T5) on rose growth CV Sarah in vitro was carried out in the Sudan University Laboratories. Data were collected for plant height, number of branches, number of leaves, and fresh weight. Statistical analysis was conducted using a completely randomized design, to find the least significant difference to compare between treatment means for MS (Murashige and Skoog) medium. Data analysis showed that the application of sugar at concentrations of 15, 30, and 45gms gave the highest means for the different growth parameters and fresh weight at a significant level, whereas the addition of sugar at 60gms concentration and sugar-free gave no significant increases. This showed clearly that addition of sugar was essential for plant growth, greater concentrations gaviz 60gm negative results, Addition of sugar at the above-mentioned concentration from 15mg,45gm to parameters studied the growth media in vitro gave a positive increase in rose growth.
