Not only the Agrobacterium strain is matter, the canola variety used might be important too. In a specific plant species, some varieties are preferred to be used for conducting genetic transformation due to its high efficiency.

ja sure. but I use Topas as control verity . so which strain is now suitable? 

Thanks

In this paper, it used GV series, GV3101. Probably you can try GV.

General recommendations for plant transformation with binaries (from the link):

• For transformation of dicots we recommend GV3101-pMP90RK and EHA105. We can not recommend LBA4404, though some people are also succesful with this strain.
• For transformation of Brachypopdium we can also recommend GV3101-pMP90RK.
• For transformation of other monocots, AGL1 and LBA4404 are often used. There exist strains of LBA4404 without and with a strep/spec resistance.

Thank you Yuan-Yeu. I found the GV3101 and transformed  it with my constructs. I confirmed a clony that hourbors my construct. But everytime I start a liquid culture, it takes 2 days to grow. Is that normal?
