Abstract
Breeding program started in 1982 to obtain new varieties resistant to scab (Fusicladium pyracanthae) and to fire blight (Erwinia amylovora). Since that time, 33 clones were selfed and hybridized in 126 combinations.
Differences among progenies were observed either with scab or fire blight susceptibility.
Oldest progenies were shoot inoculated in the field ; some hybrids, mainly from P. x ‘Shawnee’ x P. atalantioides ‘Mozart’ are promising.
Fire blight testing will be continued ; in the same time first selections will be dispatched to some french nurseries for further observations (ornamental value, hedging ability…).
