Selection of promising jojoba (Simmondsia chinensis Link Schneider) types in terms of yield and oil content

This experiment was carried out to determine the yield and oil contents of jojoba populations that were derived from a base population raised from seed in Antalya between 1999 and 2001. In the first year 59 types were evaluated, and 19 promising types were determined. In the second and third years experiments were conducted on these 19 types. Chilling, insect and disease damage was not seen during the experiment periods. However, some plants were dead where water ponded after heavy rains. The mature seeds were hand collected after they fell onto the soil in September, and their yield and oil contents were determined. The highest average yield was obtained in AA-56 with 1.17 kg/tree, followed by AA-46 with 1.04 kg, CA-28 with 0.97 kg and DA-50 with 0.83 kg. The lowest yield was recorded in BB-36 with 0.28 kg/tree. The oil content ranged from 43% to 58% over the three years. The highest average oil content was in AA-43 with 54.25%, followed by AB-11 with 56.76%, AB-8 with 55.72% and BA-21 with 54.02%. AA-56, AA-46, CA-28 and DA-50 types were shown to be promising in the area with respect to yield and oil content.
