  1. Karyotype of Lupinus hispanicus subsp. bicolor from Galicia (Northwest of the Iberian Peninsula)

    Monteagudo, Ana Belén; Lindner Selbmann, Ruth; Fortes Pérez, Rocío
    In Galicia, the northwest of the Iberian Peninsula, three Lupinus species are presented, Lupinus angustifolius L., L. luteus L. and L. hispanicus Boiss and Reuter. In the present study we present the cariotype of L. hispanicus subsp. bicolour which is an endemic form of the region. Though the difficulty to count the chromosome number, due to their very small size, 56 chromosomes were counted in this subspecie.

  2. Extended genetic resources of Dactylis glomerata subsp. izcoi in Galicia (northwest Spain)

    Lindner Selbmann, Ruth; Lema Márquez, Margarita; García de Izaguirre, Álvaro
    Dactylis glomerata subsp. izcoi, endemic to Galicia (NW Spain), includes diploid and tetraploid cytotypes. The present paper results from ongoing research on the distribution of Dactylis in Galicia. Tetraploids dominate all kind of habitats, but diploids do occur in restricted areas. After intensive exploration carried out by the Misión Biológica de Galicia, dealing with diploid populations of subspecies izcoi, 13 new diploid localities were recently detected along the ridge called >Macizo Galaico Duriense> three on the west side of the ridge and the remainder on the east, persisting in ancient habitats in the following communities: Quercetea robori-petrea, Erico-Ulicetalia, Ericion australis...

  3. Identifying Superior Snow Pea Breeding Lines

    Ron Pedreira, Antonio Miguel de; Magallanes Magalllanes, Jorge Luis; Martínez Tilve, Oscar; Rodiño Míguez, Ana Paula; Santalla Ferradás, Marta
    Thirty-three edible-pod pea (Pisum sativum L.) lines selected from single plants within 11 snow pea landraces and three elite cultivars were evaluated for their horticultural value in three field trials at Pontevedra and Lugo (Northwestern Spain). Field performance was estimated according to six traits related to earliness and duration, while horticultural value was determined by five pod traits. The global pod quality was estimated by a taste panel. Lines showed significant differences in nine quantitative traits. Significant differences were found among means of five landraces and the lines selected within them for pod length, width and weight. Cluster and principal...

  4. Relationship between maize stem structural characteristics and resistance to pink stem borer (Lepidoptera: Noctuidae) attack

    Santiago Carabelos, Rogelio; Souto, X. C.; Sotelo Bernárdez, Jesús; Butrón Gómez, Ana María; Malvar Pintos, Rosa Ana
    The pink stem borer, Sesamia nonagrioides (Lefebvre), is one of the most important insect pests of maize (Zea mays L.) in northwestern Spain. The objectives of this work were to evaluate, at different times during the growth of maize, structural traits related to the entry point and tissues on which larvae feed and to determine the relationship between these structural traits and the stem borer resistance. Six inbred lines with different levels of stem resistance to S. nonagrioides were evaluated in several trials. Potential structural resistance factors included rind and pith puncture resistance (RPR and PPR), rind thickness, length of...

  5. White maize: genetics of quality and agronomic performance

    Malvar Pintos, Rosa Ana; Revilla Temiño, Pedro; Moreno-González, Jesús; Butrón Gómez, Ana María; Sotelo Bernárdez, Jesús; Ordás Pérez, Amando
    White maize (Zea mays L.) is preferred for human consumption, but little is known about the genetic regulation of flour quality, and the potential value of genotypes adapted to temperate areas has not been reported. The objectives of this work were to assess the potential value of flint white maize inbreds from northwestern Spain and to determine the genetic effects of quality. A diallel among flint and dent white inbred lines was evaluated in northwestern Spain, and generation mean analyses were performed for three crosses representing flint by flint, dent by dent, and flint by dent combinations. Dent × dent...

  6. Influence of Growing and Storage Conditions on Bakery Quality of Traditional Maize Varieties under Organic Agriculture

    Revilla Temiño, Pedro; Landa, Arsenio; Rodríguez Saavedra, Almudena; Ordás Pérez, Amando; Malvar Pintos, Rosa Ana
    Maize (Zea mays L.) used for human consumption is frequently processed following traditional methods with unknown effects. The objectives of this research consist of studying genotypic and environmental effects on grain quality for human consumption and evaluating traditional grain processing methods. Three maize varieties were evaluated for 2 yr in two locations. Populations were significantly different for grain quality while grain yield and pericarp damage were mostly affected by environment. Moisture content varied from 24% for early harvest to 20% for late harvest, pericarp damage from 24 to 19%, and germination from 62 to 84%. Environments explained most of the...

  7. Identification of quantitative trait loci involved in the response to cold stress in maize (Zea mays L.)

    Rodríguez Graña, Víctor Manuel; Butrón Gómez, Ana María; Rady, Mohamed; Soengas Fernández, María del Pilar; Revilla Temiño, Pedro
    The effect of low temperature on the physiology of maize has been well studied, but the genetics behind cold tolerance is poorly understood. To better understand the genetics of cold tolerance we conducted a quantitative trait locus (QTL) analysis on a segregating population from the cross of a cold-tolerant (EP42) and a cold-susceptible (A661) inbred line. The experiments were carried under cold (15 °C) and control (25 °C) conditions in a phytotron. Cold temperature reduced the shoot dry weight, number of survival plants and quantum yield of electron transport at photosystem II (ΦPSII) and increased the anthocyanin content in maize...

  8. Variedades comerciales de guisante

    Amurrio, Juana Marina; Magallanes Magalllanes, Jorge Luis; Ron Pedreira, Antonio Miguel de
    Peer reviewed

  9. Las proteaginosas

    Lema Márquez, Margarita; Lindner Selbmann, Ruth
    Las proteaginosas (guisantes, altramuces y otros) son leguminosas de alto contenido en proteínas. El uso más conocido para el guisante es en verde y se consume fresco, enlatado o congelado; también se puede utilizar la vaina verde o tirabeque o el grano seco para la producción de piensos (hasta un 25% de proteína). El altramuz despierta gran interés para la agricultura moderna no sólo por su excepcional contenido en proteínas sino también por su adaptación a terrenos pobres, de reacción ácida. Se utiliza para forraje verde, heno y ensilado. Además sus semillas presentan un valor nutritivo muy elevado y se...

  10. Performance of maritime pine spanish mediterranean provenances at young ages in a transitional region between atlantic and mediterranean climates in NW Spain

    Mata Pombo, Raúl de la; Zas Arregui, Rafael
    Maritime pine (Pinus pinaster Ait.) occurs naturally in a wide variety of sites around SW Europe, from typical Mediterranean climates to areas in Northern Spain and France with a strong oceanic influence. Within its distribution range populations are strongly differentiated, showing local adaptations to environmental conditions that have been widely documented in different provenance trials both in the Atlantic region and in the Mediterranean area. In the present paper, we analyzed the performance of six Mediterranean provenances in three sites in the interior of Galicia (NW Spain), a transitional region between Atlantic and Mediterranean climates where few catalogued materials are...

  11. Preliminary evaluation of scarlet bean landraces from Spain

    Martínez Rivas, Tala; Santalla Ferradás, Marta; Ron Pedreira, Antonio Miguel de
    Scarlet bean (Phaseolus coccineus) is a frequent crop in small farms and gardens in the North of Spain and Portugal. In spite of the fact of its reduced contribution to the overall production of bean in these countries, some landraces have importance in these areas as a traditional crop for self consumption or sale in local markets (Campion and Servetti, 1991; Zeven, 1993). This species deserves also special attention due to the possibility of being a germplasm source to transfer to common bean (Phaseolus vulgaris) resistance to diseases (Vanderborgt, 1983) as well as tolerance to some abiotic stresses. In addition,...
