‘lucía myrtea’ and ‘victoria myrtea’ are early-season cultivars of Japanese plum (Prunus salicina Lindl.) typology, both characterized by their low chilling requirements, so their adaptation is ideal for warm growing areas in the current context of climate change. High productivity, high-quality fruit and attractiveness are three characteristics common to both new cultivars. ‘lucía myrtea’ and ‘victoria myrtea’ stand out for their attractive dark purplish skin; their striking and intense red flesh; and their excellent taste qualities, with firm, juicy and aromatic fruit. Another remarkable characteristic is the floral self-compatibility in the case of ‘victoria myrtea’, uncommon in Japanese

Background

The Centro de Edafología y Biología Aplicada del Segura–Consejo Superior de Investigaciones Científicas (CEBAS-CSIC) Almond Breeding Program began in 1971, when the germplasm collection was established, with the aim of obtaining new self-compatible and late-flowering cultivars. The first crosses were carried out in 1985.

Late flowering decreases the risk of late frosts coinciding with flowering or fruit formation, thus avoiding crop losses. Self-compatibility enables a cultivar to produce fruit after pollination with its own pollen, which has enormous advantages for the grower compared with traditional self-incompatible cultivars (Dicenta et al., 2002). Self-compatibility allows the grower to cultivate
