Abstract: 
The staminate kiwi (Actinidia deliciosa A. Chev) cv. GTH (Late Yellow Hayward) showed high resistance to the pathogens Pseudomonas syringae pv. syringae and Pseudomonas viridiflava, contrary to the pistillate cv. Hayward which was highly susceptible to both bacteria. The resistant staminate GTH acquired susceptibility when transformed with rolABC of Agrobacterium rhizogenes. This susceptibility was inherited by the T1 offspring containing rolABC genes, derived by crossing pollen of transgenic rolABC GTH with the pistillate cv. Hayward. The susceptibility was probably correlated to high nitrogen content in the leaves of the rolABC plants. The higher susceptibility to P. s. pv. syringae than to P. viridiflava could be correlated with the high degree of auxin production by first bacterium. The high resistance to both bacteria of the staminate GTH was inherited by all the offspring lacking rolABC genes. The possibility of reducing susceptibility of rolABC plants to the pathogens by applying fewer fertilizers in the orchards, which would reduce both costs and environmental impact, is discussed.
