Inheritance of resistance to loquat canker (Pseudomonas syringae pv. eriobotryae, group A) in loquat (Eriobotrya japonica) [Japanese]

摘要

To investigate the inheritance of resistance to loquat canker caused by Pseudomonas syringae pv. eriobotryae, Group A, 1307 and 1189 loquat (Eriobotrya japonica) progenies from 31 (Exp.1) and 15 (Exp.2) crosses, respectively, were studied. F, seedlings were inoculated with the bacterial suspension and classified as either resistant (R) or susceptible (S) based on the appearance of black-brown canker 1-2 months after inoculation.
