“…This red grape genotype, a native of the O Rosal subzone of the Rías Baixas Denomination of Origin area (Northwest of Spain), was only recently included in the Spanish Registry of Commercial Varieties (Santiago et al, 2008). Huetz de Lemps (1967) describes it as highly susceptible to powdery mildew.…”

This paper reports the susceptibility to powdery mildew of 41 grapevine genotypes growing in the north and northwest of Spain over a three-year period. Although the humid climate of these vine-growing areas is not particularly favourable to the development of this disease, serious damages appears in some years when dry weather alternates with times of some rain. All the examined genotypes belonged to the collection of the Misión Biológica de Galicia (CSIC) (Pontevedra, Galicia, Spain). The incidence and severity of powdery mildew were determined on leaves three weeks after the onset of flowering and on clusters at harvest. The values for both variables were smaller than those recorded for other fungal diseases, although great differences in susceptibility between the different genotypes were observed. The most susceptible was Castañal (recently included in the Spanish Registry of Commercial Varieties), a genotype native to the O Rosal subzone of the Rias Baixas denomination of origin area. The present results could help viticulturalists grow different grapevine genotypes more successfully in regions with climatic conditions similar to those where the study was undertaken.

“…The term was first used by Sachs in the middle 17 th century (Viala & Vermorel, 1905). It represents the study most commonly used today in cultivar identification and differentiation (Truel, 1985;Martí et al, 2007;Santiago et al, 2008), canopy management (Poni et al, 2008), comparison of rootstock effects (Bica et al, 2000), environmental impacts (Ferrini et al, 1995) and even in the history of art (Gago et al, 2009). A sub-section of this science is ampelometry which is based on the nominal characterization of grapevine leaves.…”

“…Genetic diversity is strictly related to specific different cultivation methods and local traditions (Frankel et al, 1995) which are part of the heritage of history and culture (Sereni, 1979;Santiago et al, 2008). The major cause of genetic variability among cultivars is the diversity of environments in which extensive and prolonged breeders selection takes place (Pickersgill, 1997).…”

A traditional Italian sweet pepper landrace, 'Peperone di Voghera', which faced the risk of extinction, was analyzed for its genetic, phenological, morphological, agronomic and biochemical traits. An extant population was compared with cultivars 'Quadrato d'Asti', 'Cuneo', and 'Giallo d'Asti', cultivated in the same area, in order to evaluate the chance of the landrace recovery. Amplified fragment length polymorphism (AFLP) analysis demonstrated that Voghera landrace is distinct with respect to reference cultivars, thus excluding extensive genetic contamination and providing a molecular basis of both phenological and biochemical differences. Leaf chlorophyll content is lower, fruits start ripening earlier than controls, and yield (1,100-1,300 g plant -1 ) does not significantly differ. Sensitivity to root pathogens, the main factor that led to the decline in the past, does not seem to compromise the future chance of recovery. Vitamin C concentration is high (200-240 mg/100 g) and preserved by cold storage; more than 25% of vitamin C is also kept in pickled fruits. 'Voghera' landrace has nutritional and gastronomic properties that can be appreciated by consumers. The high internal genetic variability shown by AFLP analysis indicates that future selection work is necessary to fully maintain the original traits of the landrace and to improve it.Additional key words: AFLP; biodiversity; Capsicum annuum; extinction; nutraceutical properties; root mycosis. ResumenCaracterización de la variedad de pimiento tradicional 'Voghera', rescatada en el norte de ItaliaEn este trabajo se han analizado las características genéticas, morfológicas, fenológicas, agronómicas y bioquími-cas de una variedad tradicional italiana de pimiento dulce, 'Peperone di Voghera', en peligro de extinción. Se comparó una población existente con cultivares de la misma zona, 'Quadrato d'Asti', 'Cuneo', y 'Giallo d'Asti', a fin de evaluar la posibilidad de recuperarla. Análisis AFLPs (polimorfismos en la longitud de fragmentos amplificados) demostraron que 'Voghera' es distinta con respecto a los cultivares de referencia, lo que excluye que haya una amplia contaminación genética y proporciona una base molecular de las diferencias, tanto fenológicas como bioquímicas. Su contenido en clorofila es menor y los frutos comienzan a madurar antes que los controles, pero el rendimiento (1.100-1.300 g planta -1 ) no es significativamente diferente. Su sensibilidad a patógenos de la raíz, el principal factor que llevó a su declive en el pasado, no parece poner en peligro la posibilidad de una futura recuperación. La concentración en vitamina C es alta (200-240 mg/100 g) y se preserva en el fruto conservado en cámara frigorífica; también se detecta una buena cantidad (más del 25%) de vitamina C en las frutas encurtidas. 'Voghera' tiene propiedades nutritivas y gastronómicas que pueden ser apreciadas por los consumidores. La alta variabilidad genética interna detectada en los análisis AFLP indica que el trabajo de selección es necesario para mantener plena...
