Scab resistance in progenies of varieties of the cultivated pear

Euphytica, 1960
1. Several selections from progenies from crosses between pear varieties were found to be free from scab (Venturia pirina) in one locality but susceptible when tested at another location. It is suggested that biotypes of the fungus are sharply restricted in their range of distribution at any given time. 2.

BREEDING PEARS FOR RESISTANCE TO THE PEAR SCAB FUNGUS, VENTURIA PIRINA ADERH.

Annals of Applied Biology, 1953
Clonal isolates of Venturia pinna, shown in a previous paper to differ in range of pathogenicity, have been used to inoculate the following pear seedlings: (i) resistant seedlings from families which appeared to be segregating for resistance under field conditions, (ii) two whole families of field‐resistant × field‐susceptible parentage.In (i), it was ...

Pear scab (Venturia pyrina) – toward understanding and disease management

Acta Horticulturae
European pear scab (Venturia pyrina) is an economically important disease in most of the European pear (Pyrus communis) growing areas worldwide, especially in organic pear cultivation. The dominance of scab-susceptible pear cultivars, such as ‘Conference’, is one of the major problems in organic pear growing.
