STUDY ON CULTIVAR FRANTOIO AND ITS POLLINATORS OF OLIVE IN INTERMEDIARY EXPERIMENT ORCHARD

Intermediary experiment of Olive cultivation has been carried out in Hubei and Shanxi Province from the year 1980-1987. The experiment orchards distributed in Wuchang, Yichang, Badong, Chenggu etc. eight counties (towns) with an area of 133.3 ha. in total lying between 33°10' -30°36' N latitude and 115°05'-107°00' E longtitude. This paper deals with the growth, bloom, fruitage, productivity, yield inconsistency of cultivar Frantoio and crossability with its pollinators Chenggu 32 and Leccion. According to the study, Frantoio which grew well in different locations is thought to be with a wide-range eco-adaptability. This cultivar has higher percentage of perfect flowers (80-95%) and normally sufficient fruit set obtained in self-pollination (1.96-2.40%). With good care, Frantoio starts bearing early and its productivity is fairly high. Its fruits has an approximately 79.0-79.2% flesh yield, while its oil content is higher than that of the others tested. Chenggu 32 and Leccion bloom coordinatelly with Frantoio and have a satisfactory fruit set (7.13-9.35%) in controlling pollination with Frantoio as pollinators, as they are planted together with Frantoio can promote grove's productivity.
