seasons however the lowest was that of Akka cultivar. Emanwil had the highest fruit length in both seasons. The highest fruit width was achieved by Yahoda cultivar however the lowest one was that of Akka in both seasons. L/D ratio of both Emanwil and Akka cultivars were higher than that of other genotypes. Yahoda cultivar had the highest number of seeds in both seasons. However Akka had the lowest number of seeds in both seasons. Seed weight /fruit weight ratio was highest in Zekeim in both seasons; however the lowest was found in both of Emanwil and Akka in both seasons. This means that the highest edible portion was that of Emanwil and Akka
cultivars. Emanwil had the highest pulp thickness in the first season however Akka had the highest pulp thickness in the second one. Zekeim had the highest (TSS %) in both seasons; however the lowest was that of
Akka in the first season and the Yahoda in the second one. Vitamin C had not constant trend in both seasons. The highest peel thickness was that of Emanwil fruits in both seasons. The highest juice volume resulted from
Emanwil cultivar in both seasons; however the lowest volume was that of Akka. Emanwil cultivar had the highest Leaf length, leaf width and leaf length leaf width, the lowest was that of Zekeim in both seasons.
