Self- and Cross-compatibility among Apricot Cultivars

Abstract

Eight apricot (Prunus armeniaca L.) cultivars were self- and cross-pollinated to determine pollen compatibility. Pollen tube growth in the laboratory and the percentage of fruit set in the orchard were evaluated. The results confirmed that `Moniqui Fino' and `Velázquez Tardío' are self-incompatible and established that `Gitano', `Pepito del Cura', and `Velázquez Fino' are also self-incompatible. No cross-incompatibility was found in the 25 cross-combinations.
