The contribution of Prunus webbii to almond evolution

摘要

A Spanish population of Prunus webbii, first mentioned in 1977, shows great variation for morphological traits, pointing to the possibility of hybridization with cultivated almond Most forms are self-compatible. Self-compatibility in P. webbii must beallelic with that of almond, as shown by the study of its transmission to hybrid seedlings, suggesting that self-compatibility in almond could be due to hybridization with P. webbii.
