“…The seeded berries are long ellipsoid shaped, having dark red skin color which tends to turn black at full maturity. Its cycle, productivity and susceptibility to fungal diseases are similar to 'Italia' table grape (ROBERTO et al, 2012).…”

The berry-cluster thinning technique was evaluated at different phenological times to prevent bunch compactness of ‘Black Star’ table grape, a new somatic mutation of ‘Brasil’ grape. The trial was carried out during 2012 and 2013 seaons in a vineyard situated in Marialva, PR, Brazil. Vines were trained in an overhead trellis system and spaced at 3x4m. The randomized block design was used as a statistical model with five replications and five treatments. The following treatments were evaluated: control; brushing prior to anthesis; and berry-cluster thinning at different times, when berries were 3-6, 7-10, or 11-15mm in diameter. The prevalence of bunch compactness was evaluated considering the levels: loose, medium loose, and dense bunches. The main physico-chemical characteristics of grapes and yield were also appraised. The data obtained were submitted to ANOVA, and toTukey’s test at 5% was applied. So, thinning is a mandatory practice to avoid bunch compactness of ‘Black Star’ grapes. The technique has to be performed, preferably, by means of brushing prior to anthesis, and the failure to accomplish this practice at this time, berry-cluster thinning when berries are 11-15mm in diameter can be used.

“…Além disso, vários trabalhos científicos são desenvolvidos no sentido de conhecer e melhorar os tipos de uva cultivados na região, como a mutação somática natural Black Star, originada da uva cv. Brasil em uma propriedade de Marialva (Roberto, Assis, Genta, Yamamoto, & Sato, 2012); a avaliação da qualidade das uvas (Roberto et al, 2002); estudos sobre as exigências climáticas da videira (Hiera & Silveira, 2011); avaliação nutricional e qualidade dos frutos (Tonin et al, 2009), entre outros. Essa dinâmica de pesquisa e desenvolvimento parece impulsionar o ritmo da produção territorial da uva, conforme defende Raffestin (2009) e Saquet (2009).…”

O presente trabalho tem por objetivo compreender as ações e os atores que configuram Marialva como um território produtor de uva fina. Articulam-se teoricamente questões sobre território e desenvolvimento territorial e sobre Sistema Agroalimentar Localizado (SIAL), que é um tipo de arranjo envolvendo relações de produção organizadas horizontal e verticalmente que emergem a partir da ação coletiva e da coordenação local em torno de um recurso territorializado. Para tanto, foi realizada uma pesquisa descritiva, com dados secundários e análise documental. Admitem-se avanços analíticos ao combinar a perspectiva do SIAL com uma abordagem ampliada de território, haja vista que um sistema agroalimentar localizado envolve não só aspectos econômicos e sociais, mas também aspectos políticos, culturais e da natureza, reciprocamente relacionados. Frisa-se a necessidade de que o desenvolvimento local seja alvo de discussão e análise por parte dos agentes públicos e da sociedade civil organizada, tendo em vista um maior desenvolvimento territorial.

“…They may eventually give rise to plant variants without going through the gametophytic phase. Somatic variation has a strong relevance in the generation of the cultivars ' Rubi', 'Benitaka', 'Brasil', 'Redmeire' and 'Black Star' (Kishino and Mashima, 1980;Sousa, 1996;Pires et al, 2003;Roberto et al, 2012) from cv. 'Italy' as the fundamental genome.…”

During more than 50 years the vegetative propagation has been the form of maintaining and multiplication of the cv. ’Italy’ vineyards, a ’Bicane’ x ’Muscat Hamburg’ hybrid. In the current study, polymorphism in 17 microsatellite loci was used to evaluate the genetic stability at DNA level in vineyards of cv. ’Italy’ planted in different regions of the states of Paraná and São Paulo, Brazil. Unchanged and equal allele frequency indicating genetic stability was reported in 47% of the microsatellite loci in vineyards of six localities, while allele frequency variation has been observed in Scu15vv, Udv44, Udv74, Udv96, Udv107, Udv108, Vvmd5, Vvmd6 and Vvs3 microsatellite loci. Alleles Udv96140 and Vvs3448, detected in vines in only one of the vineyards, evidenced somatic mutations at molecular level in cv. ’Italy’. Genetic diversity, as result of changes in the allele frequencies in 53% of microsatellite loci, was detected more frequently than somatic mutations due to new alleles. Polymorphism in microsatellite loci revealed different genetic stability in vineyards of cv. ’Italy’ cultivated in six different Brazilian regions and indicated vineyards with less genetic stability as a possible source of somatic mutants, showing traits of agronomic interest with a potential to generate new cultivars.
