Immature cotyledons from six cultivars and breeding lines of Pisum sativum
were cocultivated with Agrobacterium tumefaciens and selected on a medium c
ontaining kanamycin. Transformed plants were recovered with a success rate
of between 0.8 and 3.4% of explants treated. The plasmids used were based o
n pGA633 and have a nos promoter driving an nptII gene. Progeny from the pr
imary transformants showed stable inheritance of the nos-nptII gene. (C) 19
