Abstract

Pseudomonas syringae pv. actinidiae (Psa) is by far the most important pathogen of kiwifruit. Sustainable expansion of the kiwifruit industry requires the use of Psa-tolerant or resistant genotypes for the breeding of tolerant cultivars. However, the resistance of most existing kiwifruit cultivars and wild genotypes is poorly understood, and suitable evaluation methods of Psa resistance in Actinidia have not been established. A unique in vitro method to evaluate Psa resistance has been developed with 18 selected Actinidia genotypes. The assay involved debarking and measuring the lesions of cane pieces inoculated with the bacterium in combination with the observation of symptoms such as callus formation, sprouting of buds, and the extent to which Psa invaded xylem. Relative Psa resistance or tolerance was divided into four categories. The division results were consistent with field observations. This is the first report of an in vitro assay capable of large-scale screening of Psa-resistance in Actinidia germplasm with high accuracy and reproducibility. The assay would considerably facilitate the breeding of Psa-resistant cultivars and provide a valuable reference and inspiration for the resistance evaluation of other plants to different pathogens.

(A) Callus formation and buds sprouting on canes of resistant/tolerant genotype; (B) Dark-brown color on the cane with Psa ooze spilled in highly susceptible genotype; (C) Zero visible lesion symptom on high resistance genotype; (D) Lesion extended only into the outer epidermis and cortex tissues around the wound point for the resistant or moderate genotype; (E) Lesion partly extended into xylem only inside the wound side of susceptible genotype; (F) Lesion completely extended into the entire xylem and eventually the whole cane of highly susceptible genotype turned brown.
