Evaluation of some Productive and Technological Traits in Local and Introduced Olive Cultivars (Olea europaea L.)

Abstract

This research aims to evaluate some productive and technological traits for 12 olive cultivars (Olea europaea L.), to select the best of them for Propagation, and genetic improvement programs. Samples were collected from 10 introduced and 2 local cultivars, during the years 2015 and 2016, from Bouka Center in Lattakia, Syria. Cultivars were evaluated for technological and productive traits. Three trees/cultivar were analyzed. Data were subjected to ANOVA analysis.For technological traits, the fruit weight average varied between cultivars. The highest weight was found in Spanish Gordal (10.3 g) while the lowest weight was found in Algerian Chemlal cultivar (1.44g.) For stone trait, the weight average ranged between medium and very big weight. All olive cultivars showed high reflux% except Chemlal and Frantoio where they had low value.Highest value of oil percentage (26.6%) was detected in Frantoio cultivar and the lowest value was in Gordal cultivar (13.4%).Concerning the productive traits, the highest tree production of fruits was in Tanche (36.67kg/tree) and the lowest one was in Trilia cultivar (1.67 kg/tree). Picholine, Coratina, Frantoio and Khdairi cultivars showed stable yield between years while alternate bearing phenomenon was more obvious in the rest of cultivars.
