| Abstract:
Pyrus communis pear cultivars are self-incompatible, hence in these orchards inter-fertile cultivars have to be planted. Parry (1976) and Kurennoi (1985) screened the following Pyrus species as potential pollinators: Pyrus amygdaliformis, P. longipes, P. nivalis, P. salicifolia P. betulaefolia, and P. syriaca. At the INRA Angers Research Unit research into pollinators for pear varieties was initiated in 1990. A selection from Pyrus betulaefolia, the P337-41 clone, was subsequently selected as the best candidate. This genotype exhibits very abundant flowering, and a regular and extended blooming period. The latter covers the blooming time for early to late pear varieties. The clone P337-41 originating from Pyrus betulaefolia is recommended as a pollinator for the main varieties grown in France: ‘Williams’, ‘Conférence’ and ‘Doyenné du Comice’. | |
