Title: GENETIC IMPROVEMENT OF KANINJOT VARIETY FROM CLONAL SELECTION

Abstract: The "Kaninjot" cultivar, autochthonous and widespread is remarkable for high percentage and good quality of the oil. It has dual use. It has periodical production, but the variability that this genotype possesses has been exploited through clonal selection to find individuals with high production constant, oil percentage and bigger average fruit weight. The selection underwent two phases: In the first phase: over a population of 2583 trees, in a five year period, where each year the trees that were qualified had inflorescence and fructified, while the others were considered out of use. In the second phase for 17 clone candidates derived from selection of the first phase production evaluation was done for kg/trees/ year, (i) oil percentage % fresh matter done through Soxhlet, (iii) average fruit weight (g), (iv) production periodicity estimated through Pearce and Dobersek-Urbank. Each clone displayed differently its genetic potentials, with differences for production constant. Constant production had 6 individuals (0.00 – 0.30). The variability for fruit weight was from 0.26 g up to 1.24 g more than the standard (12 individual). For the oil percentage 6 individuals with 0.1 up to 2.1% more than the average of the population were selected. In the final evaluation there resulted to be: (i) 12 clones with superior PC. (ii) 6 clones possess superior for constant production and oil percentage (PC+OP). (iii) 6 clones possess the three selection features; constant production, oil percentage and fruit weight (PC+Fw+Op). The selected individuals have differences as far as the pomological and technological characteristics are concerned.

Key words: Clone; Olive oil; Cultivar; rooting capacity; Selection; Olea europaea.
