Gilvaneh, the new oil olive cultivar suitable for culture in Tarom region

Introducing olive cultivars with high oil quality is one of the objectives of olive breeding programs. Simultaneously, with the introduction of new olive cultivars from Mediterranean countries, the identification, collection, and evaluation of local genotypes was also implemented in the Zanjan Agriculture and Natural Resources Research Center. In 1997, cuttings of 25 T-olive genotypes were prepared from the Hashem Abad olive orchard of Golestan province. In 1998, the propagated plants were planted at the collection of Tarom Olive Research Station. Since 2006, with the implementation of five research projects for 15 years, the “Gilvaneh” cultivar was released by the selection method of genotypes. The “Gilvaneh” cultivar has oval leaves, the average number of flowers in an inflorescence is (22.9), the average length of the inflorescence is (27.5 mm), and the date of opening of the flowers and formation of the fruit of this cultivar occurs in the first half of May. “Gilvaneh” cultivar has medium fruit weight (2.8-3.2 gr), and the most important characteristic of this cultivar is having 70.3% oil in the dry matter of the fruit, high oleic acid (80.1%) and low palmitic acid (9.9%); Therefore, this cultivar has high oil quality among different olive cultivars and is suitable for cultivation in Tarom region.
