The conservation and characterization of grape (Vitis spp) genetic resources in germplasm banks have been the basis of its use in breeding programs that result in development of new cultivars. There are at least 10,000 grape cultivars kept in germplasm collection. The genetic diversity in 136 table grape accessions from the state of Bahia, Brazil, was evaluated. Continuous and discrete morphoagronomic traits were assessed. The clustering analysis by the Tocher otimization method resulted in 30 clusters (considering continuous morphoagronomic traits), and 9 clusters (taking into consideration multicategorical traits). There was no agreement between clusters obtained by both, continuous or discrete phenotypic descriptors, independent of the cluster method analysis used. A satisfactory genetic variability among the table grape accessions was observed.

<p style="text-align: justify;">Many physiological processes related to plant growth and development are under the influence of growth regulators, which also have an impact on pollen germination. In this study, the effects of two brassinosteroid compounds, epibrassinolide and 22S,23S-homobrassinolide, and gibberellic acid (GA<sub>3</sub>) on <em>in vitro</em> pollen germination of two table grape cultivars, ‘Italia’ and ‘Cardinal’ (<em>Vitis vinifera</em> L.), were determined. A total of 28 treatments, alone and in combination, were applied to freshly collected pollens which were sown on a basic medium with 1% agar and 20% sucrose. Petri dishes were kept at 26±1°C for 24 hours. Counting of the germinated pollens revealed that the effects of these plant hormones were cultivar- and substance-specific. The cultivar ‘Italia’ was not influenced by the treatments (the highest germination ratio being 44.4% from 0.001 mg L<sup>-1</sup> epibrassinolide) as opposed to the cultivar ‘Cardinal’. The highest germination ratio in ‘Cardinal’ was about 50% in pollens treated with 25 mg L<sup>-1</sup> GA<sub>3</sub> + 0.01 mg L<sup>-1</sup> epibrassinolide. The control group resulted in 32.38% germination. Combining GA<sub>3</sub> with epibrassinolide provided slightly higher germination ratios compared to combining GA<sub>3</sub> with 22S,23S-homobrassinolide. </p>

AbstractFor more than four decades after the introduction of cv. Italia (Vitis vinifera L.) in Brazil, several somatic mutations in the genome of cv. Italia and its somatic mutants gave rise to phenotypes which generated at least five new cultivars of fine table grapes. Since no molecular marker proved to be effective in discriminating cv. Italia (V. vinifera L.) and its coloured mutants (Rubi, Benitaka, Brasil, Black Star), primers for the long terminal repeat (LTR) sequences were developed to analyse Inter Retrotransposon Amplified Polymorphism (IRAP) and Retrotransposon-Microsatellite Amplified Polymorphism (REMAP), and investigate how the coloured cultivars derived from clonal propagations of somatic mutations are genetically structured. Primers for LTR sequences of IRAP and REMAP markers were edited from grape sequence databases available at a GenBank. Twenty-four primers, denominated DKS001–DKS024, were edited. Three hundred and forty-nine DNA segments were amplified by individual DKS primers and DKS/ISSR (Inter Simple Sequence Repeats) primer combinations, at an average of 13.96 amplicons per primer pair. High genetic divergence between the five cultivars was inferred from polymorphism in retrotransposons IRAP and REMAP. The analysis of polymorphism of IRAP and REMAP retrotransposons was crucial to show that clonal propagation of somatic mutations may lead towards the formation of genetically divergent cultivars by the formation of genetically structured vineyards and show the mixture of genomes within each cultivar.

Climate change will lead to higher frequencies and durations of water limitations during the growing season, which may affect table grape yield. The aim of this experiment was to determine the variability among 3-year old table grape cultivars under the influence of prolonged water deficit during fruit development on gas exchange, growth, and water use efficiency. Six own rooted, potted table grape cultivars (cv. ‘Muscat Bleu’, ‘Fanny’, ‘Nero’, ‘Palatina’, ‘Crimson Seedless’ and ‘Thompson Seedless’) were subjected to three water deficit treatments (Control treatment with daily irrigation to 75% of available water capacity (AWC), moderate (50% AWC), and severe water deficit treatment (25% AWC)) for three consecutive years during vegetative growth/fruit development. Water deficit reduced assimilation, stomatal conductance, and transpiration, and increased water use efficiencies (WUE) with severity of water limitation. While leaf area and number of leaves were not affected by treatments in any of the tested cultivars, the response of specific leaf area to water deficit depended on the cultivar. Plant dry mass decreased with increasing water limitation. Overall, high variability of cultivars to gas exchange and water use efficiencies in response to water limitation was observed. ’Palatina’ was the cultivar having a high productivity (high net assimilation) and low water use (low stomatal conductance) and the cultivar ‘Fanny’ was characterized by the highest amount of total annual dry mass as well as the highest total dry mass production per water supplied during the experiment (WUEDM). Hence, ‘Fanny’ and ‘Palatina’ have shown to be cultivars able to cope with water limiting conditions and should be extensively tested in further studies.

Grapes can be an abundant source for polyphenols. This work was to extend the investigation to white grape antioxidants by determining antioxidants and antioxidant activity (DPPH, ABTS and FRAP). The results suggested the polyphenols of ‘Italia’ was significantly higher than ‘Rosario Bianco’. But except FRAP, DPPH and ABTS were no difference between two withe cultivars. Moreover, the seeds of tested grape cultivars were the best source of antioxidants content and activity, followed by skins and then pulps of grapes.
