| Abstract:
Fruit, pit and leaf biometric characters were evaluated for their ability to discriminate olive cultivars. Recordings from 25 indigenous Sicilian cultivars were used. Data showed a large amount of variability among the accessions that can be considered as a valuable source of genetic traits for breeding programmes. Discriminant functions calculated using fruit characters classified correctly 87% of the observations but only less than 50% using leaf and leaf colour. No identities between cultivars were detected. Principal components analysis on the between-cultivars correlation matrix for all variables extracted 6 unrelated variables explaining >95% of total variance and showed few patterns of similarities between cultivars. | |
