Spanish Chestnut Cultivars

Abstract

<jats:p>Chestnut (<jats:italic>Castanea sativa</jats:italic> Mill.) is an important crop in Spain. This inventory of chestnut cultivars complements previous studies. We have located 152 chestnut cultivars in 131 municipalities covering 108.6 ha, with 72 new cultivars in addition to the 80 previously found. Fewer than 50% of these cultivars are extensively cultivated. Chestnuts in Spain are grown from sea level to 1100 m, but are more frequent between 200 and 800 m on northern-facing slopes. Most of the chestnuts are harvested from 25 Oct. to 10 Nov.</jats:p>

Use of Highly Discriminating Morphological Characters and Isozymes in the Study of Spanish Chestnut Cultivars

“…There are 187 cultivars documented in Spain (Pereira-Lorenzo et al, 2001a, 2001b. There is considerable need to defi ne precisely chestnut cultivar variation for improved planting regimes and chestnut breeding.…”

Production Practices and Quality Assessment of Food Crops Volume 1

“…Most of the cultivars are polyclonal, but some of them have been broadly spread (Pereira-Lorenzo et al, 1996 a and b) such as 'Parede' in Northern Spain (Pereira-Lorenzo et al, 2001a). First study reporting intra-cultivar variability was in the important cultivar Marrone Fiorentino (Borghetti et al, 1983), finding important differences between localities as it was suggested by Morettini and Saccardi (1951) previously.…”

“…Some cultivars in Spain such as Parede (Pereira-Lorenzo et al, 2001a) have been propagated profusely during last 200 years but it is difficult to explain their popularity because they produce quite small nuts. Perhaps Parede presents a better adaptability to areas where temperatures are too low to bear fruits or it is more resistant to natural conservation.…”

Composición Química De Cultivares Locales De Castañas De Tenerife: I. Composición Quimica Y Contenido De Antioxidantes Chemical Composition of Local Chestnut Cultivars in Tenerife Island: I. Chemical Composition and Antioxidant Content

“…En la descripción de las castañas analizadas (Tabla 1) se puede observar que el peso promedio por castaña (8,1 ± 2,7 g) varía en función del cultivar. Los cultivares Arafera, De Sala y Donosa presentaron los pesos mayores, y en contraste, los cultivares Corujera y Temprana son los de menor peso, especialmente esta última con 2,5 ± 0,9 g. Comparando los valores obtenidos en este trabajo con los reportados por Pereira-Lorenzo et al (2001, 2006 para los mismos cultivares se observa como los cultivares Arafera, Castagrande, De Sala, Del Haya, Grande, Mansa, Mulata y Polegre tienen un peso similar. Sin embargo, para el resto de los cultivares se obtuvieron valores inferiores a los encontrados por estos autores, excepto en el caso de Donosa que mostró un valor promedio mayor.…”
