Abstract
Pear and apple indexing in Lanxade Center, confirmed the sensitivity of the two indicators Cydonia C 7-1 and Pyronia veitchii.
The former is sensitive to the diseases belonging to the chlorotic leaf spot (CLSV) – ring mosaic (RMV) and rubbery wood (RW) – quince yellow blotch (QYB) groups.
The reactions to CLSV are most severe.
The latter is more sensitive than the pears, C 7-1 and Spy 227 by the viroses of the veil yellows (VYV) – spy decline (SDV) group.
The C 7-1 also and especially reacts to the Krikon stem necrosis (NKV) and to the raspberry bushy dwarf (RBDV).
