Necesidades de polinización en variedades de albaricoquero (Parte I): autoincompatibilidad

An important varietal renewal is taking place in apricot with the introduction of new releases from different breeding programs. Most traditional cultivars are self–compatible and their flowers can be fertilized with their own pollen to set fruit. However, some of the new cultivars are self–incompatible and must be interplanted with other compatible cultivars that overlap in flowering time. The objective of this work is to determine the self(in)compatibility of the main cultivars currently grown in Spain and of the new releases to know those that can be pollinated with their own pollen and those that need cross pollination to set fruit. Of the 55 main cultivars grown in 2019, 31 were identified as self–compatible (54%) and the other 24 as self–incompatible (42%).
