摘要：

The incidence of self-compatibility in 742 almond trees, resulting from 25 inter-cultivar crossings in which at least one of the parents is self-compatible (Genco and Tuono), was determined by means of microscopic observation of the pollen tube growth in the pistil. The data obtained are consistent with the assumption that self-incompatibility in the genus Prunus is controlled by a single, multiallelic gene whose expression in the pollen is gametophytic. The 100 per cent occurrence of self-compatible specimens in the cross where the Ferragnes cultivar is the female parent is due to the existence of an allele shared with the self-compatible cultivars used. The high number of progeny examined and the method used to ascertain the self-compatibility make the results very reliable, as opposed to other less precise methodologies or tests with few seedlings.
