Sorrento has many good traits, but some defects too: early leafing, only medium nut and kernel quality, bad adaptability to other environments.
Sorrento has many good traits, but some defects too: early leafing, only medium nut and kernel quality, bad adaptability to other environments.
The breeding program started in 1980, with the aim to obtain new cultivars more productive and with superior fruit quality; the following interesting characters were selected among the cultivars of the variety testing trial: medium-late leafing time, homogamy, high percentage of fruitful lateral buds, early bearing, resistance to X anthomonas jugl and is, reduced tree size, high kernel-shell ratio, high quality of nut and kernel.
During 1980–1983, the following controlled crosses have been made:
| Sorrento x Serr | Sorrento x Gustine |
| Sorrento x Payne | Sorrento x Midland |
| Sorrento x Pedro | Hartley x Sorrento |
| Sorrento x Tehama | Franquette x Sorrento |
| Sorrento x Chico | Franquette x Serr |
Till now, a total number of 2000 seedlings has been obtained.
