Inheritance of susceptibility to bacterial spot (Xanthomonas arboricola pv. pruni) in peach offspring populations derived from Brazilian and Japanese cultivars/selections.

ABSTRACT: Bacterial spot (caused by Xanthomonas arboricola pv. pruni) is a serious disease and difficult to control in peach cultivation, and inheritance manner of susceptibility is unclear. Five hundred and fourteen offspring and their parents from 27 peach full-sib families were evaluated for susceptibility to bacterial spot by evaluating lesion length value (LLV) after artificial inoculation to shoots from trees growing in the field. Brazilian cultivars including 'Chimarrita' and selections derived from them had notably lower LLVs ranging from 0.302 to 0.490 than those from Japanese cultivars/selections ranging from 0.514 to 1.295. Family means in offspring crossed between Brazilian cultivars/selections (low LLVs) and other cultivars/selections (high LLVs) showed rather low LLVs, wh
