“…These results contrast with these obtained in other species such as plum or plumcot progenies, in which the ripening date of seedlings was within the range of variation of the parents or slanted towards the early parent (Ledbetter et al 1994, Theiler-Hedtrich 1994. The range of variation observed for the oil content components evaluated (fruit fresh weight, flesh moisture, flesh/stone ratio both on a fresh and dry weight basis, and flesh and fruit oil content on a dry weight basis) in the sample of cultivars from the Germ-plasm Bank is similar to the range reported in some olive cultivar collections of Greece (Tsatsarelis et al 1984) and worldwide (Del Rı´o and Caballero 1994), and is even higher than the range reported in Italian collections (Preziosi and Tini 1990) and from Catalonia (Tous and Romero 1993). It seems, therefore, that the sample of cultivars evaluated is representative of the whole variability of olive cultivars.…”

Yield per tree, ripening date and oil content components (fruit fresh weight, flesh moisture, flesh/stone ratio both on fresh and dry weight basis, flesh and fruit oil content on dry weight basis) have been studied during 3 years in seedlings from crosses among the olive cultivars ‘Arbequina’, ‘Frantoio’ and ‘Picual’. Genetic and environmental variances and year‐to‐year consistency of data were estimated. Most of the traits evaluated showed a range of variability as large or even larger than either the range observed in a random sample of cultivars from the World Olive Germplasm Bank of Cordoba or the range reported in the evaluation of olive cultivars collections. Between‐years correlation coefficients showed that for a character such as oil content the values obtained in the first year could be reliable indicators of the values obtained in following years. Observations over 2 years may be required for characters such as fruit weight or flesh/stone ratio on a fresh weight basis and even more than 2 years may be required to estimate yield per tree.

“…In Italy and Jordan, the fruit harvested from mid-November to mid-December, presented very high oil content (Rotundo, 1988;Presiosi and Tini, 1990 Thus, these results confirmed the oil contents recognized for certain varieties, proven in their origin ecological areas (Loussert and Brousse, 1978), although that management practices are traditional in our local pedoclimatic conditions. Also, in the studied sample of the oleaster types noticeable oil contents were remarkably obtained for the types BM2 (23.76%), BM3 (20.95%), BMR (21.…”

For the majority of local and foreign varieties, Moroccan Picholine and oleasters types, the obtained oil content relating to the fruit fresh weight varied between 14.3% to 23%; excepted, the Picual variety, type oleastre BM2, Manzanille and Cucco varieties and Moroccan Picholine M1 type, which gave oil contents higher than 23%, respectively 23.23%; 23.76%; 23.83%; 25.14% and 25.83% compared to other cultivars. Gordal, Ascolana Dura, and Bouchouk Rkike Varieties, have given average oil content relative to the fresh matter lower than 17% for the local variety Bouchouk Rkike, 16% for Gordal variety and 16.9% for Ascolana Dura variety. Also, in studied oleaster types, noticeable oil contents were obtained especially for the types BM2 (23.76%), BM3 (20.95%), BMR (21.36%), BMM (18.09%). The Gordal and Bouchouk Rkike varieties presented the highest humidy percentage.
