ORIENTAL PYRUS ROOTSTOCKS AS INDICATORS OF PEAR DECLINE |
| Author: | H.R. Cameron |
| 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. | |
