Abstract
This study was carried out from 1999 to 2001 in Gaziantep to obtain vigorous Pistachio rootstocks with high bud take characteristics.
At the begining of the experiments, in the 1999, the parent plants were determined in the surrounding of Gaziantep. For this purpose seed of 13Pistacia khinjuk types were collected and sown. These parents were re-selected according to the growth rate of their seedlings. The male parents were selected during the same years by studying their positive characteristics as males.
Five different types of P. khinjuk have been used as female parents, and 5 different Pistacia vera, 5 Pistacia khinjuk, 5 Pistacia atlantica ve 5 Pistacia terebinthushave been used as male parents. Both interspecific and intraspecific hybridization was used. Thus 80 hybrid combination was obtained. Hybrid seeds were sown in plastic containers in greenhouse.
According to Weighted-Ranking Test, the highest scores were obtained. Among seven months old seedlings of P. khinjuk parents, the best results were obtained from FB2 x A3 (855 points), OB5 x A3 (840 points) ve OB5 x A4 (825 points).
