[Arabidopsis] Landsberg erecta and kanamycin

Dear all,

I have a T-DNA insertion line in the ecotype Landsberg erecta. I seem 
unable to select these plants on kanamycin though.
All of my wild type Ler continue to grow on kanamycin, while Col0 
plants, which I put on the same plate as a test, are staying small and 
are clearly sensitive.
I am using MS medium with 0.75% plantagar. The problem is not the 
kanamycin or the plates (since Col0 are sensitive).
All of my transgenic plants are also staying alive, while I didn't 
expect all of them to be homo- and heterozygous for the insert.
Has anybody had a similar experience with the Landsberg erecta ecotype 
(all Kana-segregation is going fine with Col0 ecotpye)

Kind regards,
