A STUDY ON THE RECENT GROWING OF A RAPIDLY PROPOGATING OLIVE CULTIVAR MIS-NAMED "IMPROVED NABALI" AND ITS EFFECT ON IMPEDING THE WEST BANK OLIVE INDUSTRY
This study deals with the impact of proliferation of a certain soft tissue olive cultivar mis-named by Palestinian commercial nurseries as "Improved" Nabali (Muhasan in Arabic) which was found among the predominant local Souri (called Nabali Baladi) olive cultivar groves in the West Bank. Its high rooting rate and rapid initial growth, especially in the nurseries, its large olive fruits, plus its mis-leading name and the unscrutinized foreign assistance resulted in an impediment rather than aid to the Palestinian olive oil industry. There has been no record or any scientific selection ever done to justify naming it "improved". This so-called "improved Nabali" was in fact found of poorer performance than the Souri by having watery soft fruits with at least 25% less oil, inferior oil quality, being less firm with less endurance and acceptability to pickling as table olives, its rejection by press owners for fear of plugging centrifuges, and its high susceptibility to infestation by various insects which attack its fruits, trunk and branches. It is recommended that this cultivar's name be altered so as to indicate that it is not improved, its planting be stopped and that grafting to the better Souri cultivar be performed on all that has been already planted from this "bad" cultivar in the Jordan River basin including the areas of the West Bank, the Gaza Strip, Jordan and Israel.
