Kanamycin is effective for selecting transformed peas

Immature cotyledons from six cultivars and breeding lines of Pisum sativum were cocultivated with Agrobacterium tumefaciens and selected on a medium containing kanamycin. Transformed plants were recovered with a success rate of between 0.8 and 3.4% of explants treated. The plasmids used were based on pGA643 and have a nos promoter driving an nptII gene. Progeny from the primary transformants showed stable inheritance of the nos-nptII gene.
