“…Significant correlation coefficients between bunch weight and grape yield and between berry weight and grape yield in both crossing combinations, suggest that these two traits are important components of yield in grapevine. Similar conclusions came from Firoozabady and Olmo [1987], Goldy [1988], Fatahi et al [2004], Fanizza et al [2005], Leão et al [2010], and Song et al [2014].…”

The mode of inheritance and the degree of phenotypic correlation between some more important agronomic traits in two offsprings obtained by direct and reciprocal crossing of cultivars 'Smederevka' and 'Gewurztraminer' were investigated in this study. In 62 genotypes from direct crossing (Smederevka  Gewurztraminer) and 66 genotypes from reciprocal crossing (Gewurztraminer  Smederevka), the traits evaluated were as follows: time of bud burst, flowering time, ripening time, bunch weight, berry weight, grape yield, sugar content of must and total acidity of must. The genotypes of F 1 generation for the investigated traits were arranged into a number of categories by the OIV method. In both crossing combinations (direct and reciprocal) for most traits, the same mode of inheritance (partial dominance, dominance or heterosis) was determined. Differences in the mode of inheritance, depending on whether the parental varieties were used as a father or mother, were found only for ripening time (partial dominance and intermediate inheritance). The prevailing mode of inheritance established for most of studied traits, regardless of the crossing method, was negative heterosis. From all examined traits, a significant influence of maternal effect was determined for the inheritance of flowering time and ripening time. In both crossing combinations, statistically significant phenotypic correlations were found between some studied traits.

“…The correlation between yield per plant and total acidity was high and positive (r = 0.88), indicating that the higher the yield, the greater the acidity of the berry. Fatahi et al (2004) obtained a negative correlation between yield per plant and content of soluble solids.…”

“…Finally, the main component 4, explaining 12.79% of the total variance was correlated with the bunches maturation, because the highest scores were obtained for the duration of the phenological cycle, TSS/TTA, TTA and TSS. Fatahi et al (2004) analyzed 90 grape varieties using principal components found that seven components were needed to explain 81% of the total variance, with the first factor was related to the berry characteristics and the second factor was associated with bunches characteristics. Looking at Table 4, it is possible to identify the variables of greatest weight in the last eigenvectors.…”

-The objectives of this study were to evaluate the performance of cultivars, to quantify the variability and to estimate the genetic distances of 66 wine grape accessions in the Grape Germplasm Bank of the EMBRAPA Semi-Arid, in Juazeiro, BA, Brazil, through the characterization of discrete and continuous phenotypic variables. Multivariate statistics, such as, principal components, Tocher's optimization procedure, and the graphic of the distance, were efficient in grouping more similar genotypes, according to their phenotypic characteristics. There was no agreement in the formation of groups between continuous and discrete morpho-agronomic traits, when Tocher's optimization procedure was used. Discrete variables allowed the separation of Vitis vinifera and hybrids in different groups. Significant positive correlations were observed between weight, length and width of bunches, and a negative correlation between titratable acidity and TSS/TTA. The major part (84.12%) of the total variation present in the original data was explained by the four principal components. The results revealed little variability between wine grape accessions in the Grape Germplasm Bank of Embrapa Semi-Arid. Index terms: germplasm, grapevine, grape cultivars, Vitis spp., multivariate analysis. DIVERSIDADE GENÉTICA DE UMA COLEÇÃO BRASILEIRA DE UVAS PARA VINHO BASEADA EM CARACTERES MORFOAGRONÔMICOSRESUMO -Os objetivos deste trabalho foram avaliar o comportamento agronômico, quantificar a variabilidade e estimar as distâncias genéticas de 66 acessos de videira destinadas à elaboração de vinhos, presente no Banco de Germoplasma de Videira da EMBRAPA Semiárido, em Juazeiro-BA, Brasil, por meio da caracterização de descritores fenotípicos de variação contínua e discreta. As técnicas multivariadas utilizadas, componentes principais, método de otimização de Tocher e projeção gráfica das distâncias foram eficientes no agrupamento dos genótipos mais similares, de acordo com as suas características fenotípicas. Não houve concordância na formação dos grupos pelo método de otimização de Tocher, quando foram avaliadas características morfoagronômicas de variação contínua e discreta. A utilização de variáveis discretas permitiu a separação de Vitis vinifera e híbridos em grupos distintos. Correlações significativas positivas foram observadas entre peso, comprimento e largura de cachos, bem como correlação negativa entre acidez total titulável e relação SST/ATT. 84,12% da variação total presente nos dados originais foram explicados pelos primeiros quatro componentes principais. Os resultados obtidos demonstram que existe pequena variabilidade entre os acessos de uvas para vinho no Banco de Germoplasma da Embrapa Semiárido.

The origins of the main cultivar groups of Vitis vinifera, their relationships with wild grapevine populations, and the use of other Vitaceae are relevant issues for the improvement and conservation of Vitis diversity. Morphometric studies, domestication indices, multivariate analyses, and Bayesian hypothesis testing have been used. Eight different seed types have been identified in the 24 samples analyzed from materials from the Upper Euphrates sites of Tell Khâmis and Tell Qara Quzaq (Early Bronze Age to Hellenistic), ranging from highly domesticated to purely wild. We have been able to establish the predominance among the domesticated of Proles orientalis Negrul (three samples, Domestication Index = 1), the existence of and extinct Proles euphratica (six samples, Domestication Index = 0.67–0.83) and numerous intermediates and hybrids (eight samples). We have determined the continued presence throughout the period studied of wild grapevines related to Vitis sylvestris C.C.Gmelin and V. caucasica Vavilov (5 samples, with Domestication Indices = 0.17–0.5). The existence of Ampelopsis seeds was established for three samples. We determined that the oldest Vitaceae seed linked to human presence, in the Acheulense (780 myr), also belongs to Ampelopsis. Finally, “stenosperms” appear associated with Ampelopsis seeds (three samples), suggesting anomalies in seed formation due to intergeneric cross-pollination. Moreover, if isolated, they suggest the presence of “stenospermocarpic” Vitis vinifera raisins of the Sultanina type. Finally, we must reflect on the role that Ampelopsis species may have played and their possible cultivation and domestication almost 4000 years ago.
