Abstract
In the table grape industry, because of a number of critical factors as the high specialization of the crop, the qualitative standards required by the consumers, the high costs of production and the recurrent problems of market, every technical mistake in the establishment of new vineyards can vanish all the heavy investments required. The genetic and sanitary quality of the propagating materials is the key element for the economic success of the new vineyards; however in Italy only 4 major (Cardinal, Italia, Matilde and Regina bianca) cultivars have certified clones registered in the Italian National Catalogue of grapevine varieties, consequently the sanitary status of propagation material still represents a serious unsolved problem. As result of a long clonal and sanitary selection activity, 15 new clones, named with acronym CRSA and belonging to 11 different varieties cultivated in Apulia (South-east Italy), have been recently approved for registration by the official Committee of the competent Ministry. The results of the pluriannual evaluation conducted with 26 candidates in comparative trials demonstrate that the 15 selected clones show, for some characteristics as productivity, morphology of cluster and berry, ripening uniformity, organoleptic properties and percentage of berry shooting, performances significantly higher of the varietal standards. For the most widespread varieties as Victoria and Michele Palieri they represent in absolute the first registered clones while for Cardinal, Italia, Matilde and Regina bianca, the clones, differentiable for agronomic-productive traits, will enrich the number of clones available. Concerning other varieties, traditionally vocated but actually underused (Almeria, Baresana, Ciminnita, Lattuario nero, Regina dei vigneti), the availability of certified clones could contribute to revitalize their cultivation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
