Abstract
This study was carried out in 1996-2000 years for breeding ofPistachio rootstocks in order to obtain, fast growing, vigorous and buddingcompatible with cultivars.
At the begining of the experiments, in the 1996-97, the parent plants were determined in the surrounding of Gaziantep.
Five different types of P. khinjukand ofP. verahave been used as female parents, and 6 different P. veraand of P. khinjukhave been used as male parents. Both interspecific and specific hybridization was used. Thus 120 hybrid combination was obtained. Hybrid seeds were sown in plastic container in greenhouse.
According to Weighted-Rankit test, the highest score obtained fromSiirt x Male 46 (Kaska), Uzun x Male OBE-3, Halebi x Male 46 (Kaska), Ohadi x Male 46 (Kaska), Kallaghochi x Male 46 (Kaska), SB-2 x Male 12, SB-2 x Male 4, OB-1 x Male 5,AB x Male14 (Atli), AB-2 x Male KE and OB-8 x Male 10.
Among seven months old seedlings of P. vera parents, the best result was obtained from Ohadi x Male 46 (Kaska male cultivar) and Siirt x Male 46 (Kaska), among P. khinjuk parents, the best result was obtained from OB-1 x Male 5 andAB-2 x Male KE.
