La disponibilidad de un método rápido y eficiente para comprobar la paternidad de los individuos procedentes de un cruzamiento es un requisito indispensable en cualquier programa de mejora genética. Esto es especialmente importante en el caso del olivo, ya que el nivel de autocompatibilidad es alto.

Previous analyses of olive (Olea europaea L.) crosses have revealed an important degree of pollen contamination. For this reason, the authors tested the paternity of a set of progenies coming from crosses among different cultivars within the olive breeding program of Cordoba, Spain, using four polymorphic microsatellites. They found that the...

We studied the self-incompatibility of two main Spanish olive (Olea europaea L.) cultivars, 'Picual' and 'Arbequina', by testing the selfing of the seeds with microsatellites. For this purpose, we used a rapid single-seed DNA extraction method and four highly polymorphic microsatellites. We analyzed seeds produced in branches bagged for selfing...

Con el fin de establecer una alternativa de polinización al uso de ácido giberélico en la producción del cultivar de peral Agua de Aranjuez, se han evaluado las relaciones de inter-incompatibilidad de Agua de Aranjuez con 17 cultivares coincidentes en floración con este cultivar. De los 17 cultivares estudiados 3 resultaron no aptos como polinizadores.

Bactrocera oleae (Rossi), the olive fly, represent an important biotic factor in olive groves (Olea europaea L.) causing significant production losses. Ensuring effective management of this pest is of paramount importance to safeguard and uphold the quality and quantity of table olive production. The University of Seville's (US) table olive...

The number of local and traditional fruit cultivars in Andalusia (Southern Spain) has decreased dramatically since the 1970s when new commercial cultivars from breeding programs were introduced, replacing old varieties, and thus decreasing genetic diversity. The present study was included in a genetic resources project with the objective of...

The olive tree is well adapted to the Mediterranean climate, however, the current increase in temperature as a consequence of the global warming affects the phenological stages and can accelerate the ripening of the fruits, moving the harvesting to periods that are less favorable for quality production. In this work, the impact of harvesting...

At a time of increasing demand, the extremely high cost of manual labor required to harvest fruit in table olive groves is limiting the economic survival of the crop in many producing countries. New grove designs and management practices such as superhigh-density (SHD) groves now in use in oil olive production should be explored as an option to...

Andalucía es la segunda región productora de cítricos de España, teniendo por tanto una extraordinaria importancia económica y social. Sin embargo, la cadena de valor de los cítricos comprende un sector productor bastante atomizado frente a unos compradores muy concentrados y organizados, y un mercado poco transparente. El objetivo de esta...

Old traditional cultivars are valuable genetic resources for crop improvement, but a great number of them have disappeared in the past century. This study aimed to characterize traditional cultivars of different Prunus species collected in small family orchards in southwestern Spain and to evaluate their genetic diversity and relationships....

BACKGROUND Mechanical harvesting with over-the-row harvesters in super-high-density (SHD) table olive orchards increases the effectiveness of fruit removal, although bruising can limit the fruit quality. Additionally, an early harvest in periods less favourable to quality production is increasingly frequent as a result of global warming. The...

Actualmente el sector del olivar en España incluye dos subsectores claramente diferenciados por su aprovechamiento: el olivar de almazara y el de mesa o verdeo, cada uno con unas particularidades específicas que los diferencian, tales como variedades empleada s y técnicas de cultivo como la poda o la recolección. En los últimos años, la...

Sexual reproduction in olive is carried out for purposes such as breeding. The seedlings evolve from the juvenile to the adult stage, and until now, only the discrete developmental phases have been investigated in detail. However, the transition process has been poorly studied in fruit trees, especially in olive. In this paper, juvenile to...

Las plantaciones superintensivas de olivar (Olea europaea L.), con densidades superiores a los 1.000 árboles por hectárea, se han convertido en una interesante alternativa al cultivo de olivar de almazara en la que el coste de recolección disminuye por la drástica reducción de la mano de obra y del tiempo requerido por el empleo de cosechadoras...

Thirty-three new genotypes coming from a table olive cross-breeding program were evaluated to assess their adaptability to standard processes, namely Spanish-style and black ripe olives. Different physical and chemical parameters were evaluated in fresh fruits, processed olives and brines. Most of these traits exhibited large variability...

Super-high density olive orchards may increase proftability for table olive producers. However, water needs and fruit dam age could limit their viability. Defcit irrigation scheduling would reduce the amount of water required, but rehydration before harvest is extremely important. The aim of this work was to compare a typical defcit farm...

Los contenidos prácticos constituyen una parte fundamental del programa de la asignatura Propagación Vegetal, impartida en la Escuela Técnica Superior de Ingeniería Agronómica (Universidad de Sevilla), y representan cuatro créditos de un total de seis. Con ellos se pretende consolidar y aplicar los conocimientos teóricos, practicar determinadas...

Airborne methodologies based on unmanned aerial vehicles (UAV) are becoming an extraordinary tool for implementing fast, accurate and affordable phenotyping strategies within plant breeding programs. The aim of this paper was to study the potential use of a previously developed UAV-OBIA platform, to fasten and support decision making for olive...

The need for the olive farm modernization have encouraged the research of more efficient crop management strategies through cross-breeding programs to release new olive cultivars more suitable for mechanization and use in intensive orchards, with high quality production and resistance to biotic and abiotic stresses. The advancement of breeding...

New super-high-density (SHD) olive orchards designed for mechanical harvesting using over-the-row harvesters are becoming increasingly common around the world. Some studies regarding olive SHD harvesting have focused on the effective removal of the olive fruits; however, the energy applied to the canopy by the harvesting machine that can result...
