ORIENTAL PYRUS ROOTSTOCKS AS INDICATORS OF PEAR DECLINE

Article number

67_58

Pages

339 – 339

Language

Abstract

Two Pyrus ussuriensis clones were selected as preferred indicators of pear decline from 73 oriental pear seedlings.
The selection ‘Ping Ding Li No 7’ is easily propagated by cuttings and expresses distinct symptoms on grafted plants when the scion has been inoculated with the pear decline organism.
