Abstract

Ilam is one of the rich olive germplasm resources in Iran. Identification and study of adaptation of native olive genotypes is of great importance for establishment of olive orchards. This research was carried out on 15 olive genotypes collected from Ilam province to evaluate pomological and fruit yield in comparison with cv. Amphissis as check cultivar from 2015 till 2018 at Sarpole-e-Zehab Olive Research Station, Sarpol-e-Zahab, Iran. The experimental design was randomized complete block with three replications. The results showed that pomological traits such as fruit, pit and flesh weight, flesh: pit ratio, fruit and pit dimensions were significantly different among genotypes. Fruit weight varied from 3.28 to 7.92 grams among olive genotypes. Fruit yield also differed among genotypes, BSCH2, BSCH3, SKE7, SKE8, BSCH1, DZ4 and SBM5 had higher fruit yield. Oil content in dry matter was significantly different among genotypes. Oil content in dry matter of NS3, SBM2, SBM1, SKE7, DZ4, PG3 and NS4 genotypes varied from 30-40%, and categorized as low oil olive genotypes. In general, results showed that BSCH2, BSCH3, SKE7, SKE8, BSCH1, DZ4 and SBM5 genotypes performed as promising genotypes with higher fruit yield at eight to nine years old trees and can be used for being released as new cultivars as well as establishing of new olive orchards.
