Abstract: 

The biotechnological lines of spring canola (Brassica napus L.) have been created due to the introduction of both synthetic enolpiruvate shikimate phosphate syntase gene and phosphinothricin acetyl transferase gene, which are responsible for the plant resistance to glyphosate and phosphinothricin, or glufosinate, respectively, in the same vector using Agrobacterium tumefaciens-mediated transformation of leaf disks of aseptic plants of two released Ukrainian varieties (Exgold and Titan). Molecular biological analyses showed the target gene integration into canola’s nuclear DNA. Resistance to Hurricane Forte, as well as BASTA herbicides, was proved under in vitro conditions. The glyphosate and phosphinothricin worked as active agents in the mentioned herbicides, respectively. The planting of biotechnological canola plants that simultaneously express resistance genes to herbicides from two different groups may be more effective in comparison with plants, which possess only one of such genes because of the opportunity of herbicide interchange under the applications. It decreases the probability of the emergence of spontaneously tolerant weeds.
