“…The high incidence of virus infections in small populations of local varieties complicates their clonal selection (Salazar, 1985;Borgo et al, 2000;Poljuha et al, 2004;Spinthiropoulou et al, 2004;Materazzi et al, 2006;Zduniç et al, 2007). In Majorca two main factors may have lead to such a virus incidence.…”

Three autochthonous grapevine varieties of Majorca (Spain) were analyzed for the presence of viruses listed by the international certification programs. Enzyme-Linked Immuno-Sorbent Assay (ELISA) screenings were performed in 193 vines from 46 vineyards included in a clonal selection. Virus-free vines were only 6.4%, 9.6% and 11.5%, in Manto Negro, Callet and Moll, respectively. Infections by grapevine leafroll associated viruses (GLRaVs) were ascertained in 71%, 78% and 60% of Manto Negro, Callet and Moll vines, respectively. Each variety was also highly infected by Grapevine fanleaf virus (GFLV) and Grapevine fleck virus (GFkV). The percentage of plants displaying multiple infections was 58.4% in Manto Negro, 63.8% in Callet and 42.6% in Moll. Thus, it was very difficult to identify virusfree clones with suitable agronomic characteristics to be considered as a reference for the grape market. In order to obtain certified propagation material under such conditions of endemic viral infection, sanitation should be the main focus in clonal selection processes. However, the time and financial requirements for proper sanitation process bring to consideration the need to use, at least temporarily, standard multiplication material while certified clones are achieved.Additional key words: autochthonous varieties, grapevine certification, standard material virus incidence. Resumen Incidencia de las infecciones víricas en antiguos viñedos de tres variedades de vid autóctonas de Mallorca: consecuencias sobre las estrategias de la selección clonalEn este estudio se analizó la presencia de las virosis contempladas por las leyes internacionales en tema de certificación en tres variedades de vid autóctonas de Mallorca. Para ello se realizó el test ELISA (enzyme-linked immunosorbent assay) sobre 193 cepas procedentes de 46 viñedos incluidos en un programa de selección clonal. Las cepas que resultaron libres de los virus analizados fueron el 6,4% en Manto Negro, el 9,6% en Callet y el 11,5% en Moll. Los porcentajes de cepas infectadas por los virus asociados al síndrome del enrollado de la vid (GLRaVs) fueron 71% en Manto Negro, 78% en Callet y 60% en Moll. Se detectaron también altas tasas de infecciones para el virus del entrenudo corto infeccioso de la vid (GFLV) y el virus del jaspeado de la vid (GFkV) en las tres variedades. Los porcentajes de cepas sujetas a infecciones múltiples fueron 58,4% en Manto Negro, 63,8% en Callet y 42,6% en Moll. Por tanto fue difícil encontrar cepas que cumpliesen tanto los requisitos sanitarios para la certificación como aquellos agronómicos necesarios según las exigencias del mercado vitivinícola. En tales condiciones de infecciones víricas endémicas, el saneamiento debería ser el primer objetivo a seguir con el fin de obtener material de propagación certificado. Sin embargo, el tiempo y los recursos económicos necesarios para llevar a cabo el proceso de saneamiento conllevan la necesidad de considerar el uso temporal de material de propagación estándar hasta que se obtengan clones cer...

Micropropagation of Vitis vinifera L. cv. ‘Malagouzia’ and ‘Xinomavro’

Abstract:The effects of six basal media on in vitro shoot proliferation of the greek grapevines Vitis vinifera L. cv. 'Malagouzia' and 'Xinomavro' were investigated. Galzy and Zlenco proved to be the most effective for 'Malagouzia' and 'Xinomavro', respectively. If only BA was present in the medium, shoot development was poor and the plantlets were chlorotic. When the medium was supplemented with BA and NAA, growth was enhanced. The best ratio (in μM) of growth regulators was 0.5/0.3 for 'Malagouzia', and 0.1/0.03 for 'Xinomavro', which resulted in the highest number of microshoots per explant and greatest proliferation rate. The development of 'Malagouzia' and 'Xinomavro' explants at 21±2 and 26±2°C was also investigated, revealing the higher temperature to be more effective. Regarding rooting, 0.5 μM IBA improved root formation at 26°C for 'Malagouzia' and 0.5 μM IBA at 21°C for 'Xinomavro'. Moreover, 0.5 μM IBA resulted in a higher rooting percentage (>95%) and proved to be more beneficial for the overall morphological appearance of the plantlets of 'Malagouzia'. After acclimatization, survival of microshoots cultivated in media with IBA was higher than those in NAA.

“…Nearly all of them were identified and discriminated either by the corresponding toponym of the cultivation area or by an adjective referring to a particular and well-observed feature. In recent years, some "heretic" statements, judging on the phenotypic characteristics, referred that "Asproudes" represent groups of white varieties that need to be separated [6], regardless of how difficult the task might be [7]. Therefore, a working hypothesis was emerged, according to which the term "Asproudi", together with its variants (e.g., "Asprouda", "Asproudes"), is a general term that has served as a verbal repository for grouping in the same heterogeneous group different varieties, exclusively on the basis of their light berry color and their time of maturation.…”

An interesting way to maintain genetic diversity in the vineyard could be based on selecting the desirable characters of each clone or variety in order to produce a high-quality poly-clonal or poly-varietal wine, according to the consumer’s desire. The current study describes a holistic approach in viticulture towards wine production, applying a multidisciplinary methodology. Firstly, “Asproudi”, a rare Greek variety, was analyzed molecularly. The initial hypothesis that “Asproudi” is a distinct variety was questioned; microsatellite analysis showed that “Asproudi” is a population of different genotypes, at least in the Monemvasia Winery vineyard. A targeted harvest of each genotype was performed during the same day and was followed by micro-vinifications. All standard analyses of must and wine were performed in the laboratory, while a sensory analysis by a professional team evaluated each of the produced wines, showing distinctive differences. The genetic relationship of some of the Monemvasia Winery “Asproudi” genotypes to the varieties maintained in the reference collection was revealed whereas some other genotypes remained unknown.
