Abstract

The aim of this study is to select promising wild apricot rootstocks among wild apricot populations propagated by seeds naturally found in Malatya, Erzincan, Nev?ehir, Sivas and Elaz?g provinces. In the first stage, land scans were carried out between 2007 and 2009 and 756 genotypes were determined which could be suitable for the characteristics of the rootstock by considering the phenotypic characteristics. On land surveys,  the wild apricot trees that are healthy, productive, bitter seeds, thornless, dwarth growth habit and smooth trunk structure was selected. Among the marked wild apricot types were selected 240 types in 2008, 262 types in 2009 and 254 types in 2010. Seeds taken from these determined wild apricot trees were planted for 2 years in Erzincan and Malatya locations and germination experiments were carried out. In the study, Hasanbey and Hac?halilo?lu apricot varieties were used as control plants. Seed germination percentage, seedling diameter, height, diameter and high homogeneity were determined. At the end of three years of germination experiments were evaluated according to weighting ranking score and finally 8 types that has hight score selected for Malatya location and 18 types for Erzincan location. In the second step, these 26 types after selected in germination tests, was grafted by cv. Hac?halilo?lu in Malatya and by cv. Hasanbey in Erzincan. After grafting success, shoot diameter, homogenity, shoot length and homogenity were evaluated. Then, the data was selected according to weighting ranking score and finally 7 types (58/6, 58/7, 24/111, 24/7, 24/25, 24/33 and 44/8) that has hight score selected for Malatya and Erzincan locations, and transferred to the third stage. In third stage, collection orchards will be established and rootstocks-scion, yield, phenological observations, pomological analysis, tree growth and habit will be evaluated.
