Abstract:
This study was carried out at the Pistachio Research Institute to obtain new
male and female pistachio cultivars by hybridization of domestic and foreign
cultivars since 1996. Siirt, Ohadi, Haciserifi, Kalehghouchi and Sel 14 cultivars have
been used as female, and Uygur, Atli and Kaska used as male parent in this
research. The seeds of Kalehghouchi and Akbari cultivars were sown in the pots in
order to obtain chance seedlings. To get new pistachio genotypes, 3500 F1 hybrid
plants and chance seedlings were obtained and planted in Pistachio Research
Institute’s area by 90 x 40 cm in space in 1997 and 1998. Five male types have been
selected among the plants with respect to phenological characteristics, pollen
production, pollen germination and flowering period. Four female types selected for
more yield, high splitting ratio, largeness, kernel ratio, kernel colour, suture opening
and dehulling easiness as to Weighted-Rankit.
