‘Alisio 15®’, a new peach [Prunus persica (L.) Bastch] for the fresh market, resulted from a cross made in Murcia (Spain) as part of the IMIDA-NOVAMED breeding program with the aim of breeding new early-ripening cultivars with dark red skin, good size, and high sugar content as an improvement over other early cultivars currently available. This cultivar combines very early-season ripening, extensive red-blushed skin, and very good eating quality of the fruit. Few peaches in the Mediterranean area are marketable in the very early season (mid-April to early May) and the European-wide demand for early-maturing peaches

The effects of carbon source and concentration and of seedcoat were tested on the in vitro germination of peach seeds derived from crosses performed in the field. Seeds were extracted from the fruit and cultured in Woody Plant Medium (WPM) supplemented with sucrose, glucose, or sorbitol at concentrations of 15, 30, and 45 g·L−1. The percentage of germination as well as the root and hypocotyl lengths were measured after the stratification process and before acclimatization. Seedcoat did not have any influence on seed germination in any tested media and genotype. Glucose at a concentration of 15 g·L−1 and sucrose at 15, 30, and 45 g·L−1 resulted in greater stem seedling growth. The root developed the most when seeds were cultured in media with 15 or 30 g·L−1 of sucrose.

‘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
