- Title
BREEDING PEARS FOR RESISTANCE TO THE PEAR SCAB FUNGUS, VENTURIA PIRINA ADERH.
- Authors
STANTON, W. R.
- Abstract
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 found that clones of the fungus could infect some of the seedlings hitherto regarded as field-resistant. In (ii), segregation for susceptibility in the two families varied, according to the clone of the fungus used, from approximately a 1:1 ratio down to 'all resistant'. Resistance to individual clones appeared to be dominant to susceptibility, but further data are required before attempting a complete interpretation. There was a general correlation between susceptibility to the different clones. Those that produced the most infection were isolated from the parental varieties of the seedlings. This correlation was not, however, complete and clones differing in host origin tended to attack different groups of seedlings.
