Evaluation of The Most Important Apple Varieties in Syria


Abstract in English

Twenty apple varieties were evaluated in the germ plasm of the Agricultural Scientific Research Center in Swaida for Morphological traits, bud honological stages, days after full bloom, storability which were ranged between 2.5 – 8 months, and best susceptibility (e.g. wooly aphid and powdery mildew), all studied varieties showed low susceptibility to wooly aphid, while Jersy Mac revealed high susceptibility to powdery mildew compared with the other varieties. The yield of all varieties was studied, so, they divided into: high yield varieties such Stark Earliest, Royal Gala and Golden 972; Good yield varieties "Golden Delicious, Starking Delicious, and Granny Smith etc."; and moderate yield varieties" Red Spur Delicious and Rome Beauty". Chemical analysis (Total soluble solids and total sugars) were achieved for all studied apple varieties. Apple Varieties were divided into five groups depending on Days After Full Bloom (DAFB). The present investigation indicted the high quantitative and qualitative traits of studied varieties which candidate for credence and distribute them in suitable environmental areas in Syria.
