Fruit quality attributes were studied for two consecutive years in forty-three apricot cultivars and selections grown in a Mediterranean climate. Physical parameters (weight, size, flesh and skin colour, percentage of blush, firmness and percentage of dry matter), chemical parameters (total soluble solids content and acidity) and sensory parameters(More)
The effects of different factors on the control and reversion of hyperhydricity during the in vitro propagation of Prunus armeniaca were studied. Treatments that decreased the hyperhydricity but did not affect micropropagation rates were the use of the bottom cooling system for 1 or 2 wk and agargel as gelling agent in ‘Helena’, whereas the best results(More)
In this study different aspects of the in vitro introduction and establishment of apricot cultivars were investigated through meristem tip culture. The best time to introduce the meristems of ‘Canino’ was when buds were starting to swell. Various plant growth regulators were used at different concentrations on four distinct apricot cultivars to promote the(More)
Thirty-seven apricot varieties, including four new releases (Rojo Pasión, Murciana, Selene, and Dorada) obtained from different crosses between apricot varieties and three traditional Spanish cultivars (Currot, Mauricio, and Búlida), were separated according to flesh color into four groups. The L*, a*, b*, hue angle, and chroma color measurements on the(More)
Mitochondrial fatty acid β-oxidation disorders (FAOD) are main targets for newborn screening (NBS) programs, which are excellent data sources for accurate estimations of disease birth prevalence. Epidemiological data is of key importance for the understanding of the natural history of the disorders as well as to define more effective public health(More)
Time of flowering was studied during 3 years in a BC1 apricot progeny of 73 seedlings derived from a cross between the F1 selection “Z506-07” (“Orange Red” × “Currot”) and the Spanish cultivar “Currot”. Results indicated a quantitative inheritance of flowering time in apricot with an influence of juvenility and environmental conditions (chill accumulation)(More)
Evaluation of Plum pox virus (PPV) resistance is a laborious and expensive task, and the development of new accurate methods, including the use of molecular markers, would be very useful for breeding programs for resistance. In this work, the Plum pox virus resistance of 80 apricot genotypes of different genetic origins was evaluated in controlled(More)
Pollen tube growth dynamics along the style at different times after self- and cross-pollination of four heterozygous self-compatible (SfSx) almond cultivars were studied by means of fluorescence microscopy. Results showed a reduction of pollen tube number along the style following both self-pollination (half-compatible reaction) and cross-pollination(More)
In this study, 17 peach simple sequence repeat (SSR) sequences were used in the exploration of the genetic heterozygosity level of several apricot cultivars from Spain, France, Greece, and the USA, and 23 descendants. The genotypes can be classified in three groups as a function of their genetic heterozygosity (1) local cultivars from Murcia (Spain)(More)
Twelve important pomological traits related to fruit quality were studied during 3 years in an F1 apricot progeny of 160 seedlings derived from a cross between the Spanish selection ‘Z701-1’ and the South African cultivar ‘Palsteyn’. Results indicated quantitative transmission of most of the fruit quality traits studied. In addition, a clear influence of(More)
