Does anyone have Landsberg ecotype of Arabidopsis without erectamutation?

Hi, all I am currently doing genetic mapping job and using Ws and Ler as
two background. However, the erecta mutation in Ler led to some problems
for me. I wonder if someone has landsberg lines with normal version of
ERECTA gene?

Thanks a lot
