Yeasts were isolated from three vineyards located in the South Region of Brazil. A cross evaluation was carried out at the oldest vineyard of the study in Pinheiro Preto. Samples of grape berries, grapevine leaves and the soil, along with samples of the winery equipment and effluent, were collected. In the Serra do Marari and Campos Novos vineyards only samples of grape clusters were obtained. The 106 yeast isolates were identified by sequencing the D1/D2 domain of LSU rDNA or ITS1-5.8S-ITS2 region in 22 species. The values for the richness indices varied between the vineyards. A comparison of the taxonomic diversity of the yeasts from these regions using the reciprocal Simpson index showed a significant difference between the Serra do Marari and Campos Novos vineyards (5.72 ± 0.36 and 2.92 ± 0.36, respectively, p < 0.0001). The functional diversity was assessed in relation to the use of carbon and nitrogen sources by the yeasts isolated from each location. In general, we observed that the Pinheiro Preto and Campos Novos vineyards differed consistently from the Serra do Marari vineyard according to these indices (FAD2, FDc and Rao, p < 0.0001). The possible spreading of Saccharomyces cerevisiae from the winery to the vineyard in Pinheiro Preto was observed. © 2017, Springer Science+Business Media Dordrecht.

In Brazil, the average yield of sweet potato is consistently below the potential of the crop due to the cultivation of local varieties and unimproved genotypes. Increase in yield is achieved by the adoption of appropriate cultural practices and use of more productive cultivars. Thus, the aim of this study was to evaluate the performance of root yield traits in sweet potato cultivars. Six sweet potato cultivars were evaluated: Princesa, BRS Amelia, BRS Cuia, Brazlândia Roxa, Beauregard and BRS Rubissol in an experiment conducted in Canoinhas-SC. These cultivars were planted in the field, in the agricultural years 2012 and 2013, in a randomized block design with three replications and plots consisting of 11 plants. At 150 days after planting, the plants were harvested and the root yield components were evaluated. In general, the cultivars assessed in this study are good choices for sweet potato growers, with yields greater than the country's average. Cultivars Beauregard and BRS Rubissol showed the best results for the traits related to root yield. Cultivars Princesa, BRS Amelia and BRS Cuia showed intermediate performance for commercial roots, especially in the second year of the assessment. The cultivar Brazlândia Roxa had the worst performance for yield root characters at 150 days after planting, which was probably due to its longer cycle.

The replacement of open-pollinated carrot cultivars by hybrids is a reality in the seed market. We aimed to evaluate the productive potential of experimental carrot hybrids, tolerance to leaf blight as well as the uniformity of roots, compared to open-pollinated cultivars. Eighteen carrot genotypes, 15 experimental hybrids, one commercial hybrid (Juliana) and two open-pollinated cultivars (OPs) (Brasília and BRS Planalto) were evaluated in the 2011/12 crop in Brasília, Brazil, in randomized blocks design with three replications in plots of 2 m2. At 90 days the incidence of leaf blight was evaluated and at 100 days we measured production component characters, in addition to taking at random 50 roots per plot for individual measures. Difference was observed for all traits among the genotypes, hybrid being better or worse than OPs. For total root yield, no contrast was found between hybrids and OPs. However, hybrids showed higher amount of marketable roots compared to OPs. Regarding uniformity of root lenght, OPs were similar to hybrids, but more irregular in relation to diameter and individual weight. The results demonstrate superiority of hybrids in relation to OPs for marketable production and uniformity of roots. © 2015, Sociedade de Olericultura do Brasil. All rights reserved.

The objective of this study was to identify the best time of desiccation of plants to promote skin quality without detriment of potato cultivar BRS Clara. The experiment was carried out at Embrapa Produtos e Mercado, Canoinhas, Santa Catarina state, Brazil. 'Agata' was used as the control cultivar. The treatments were four desiccation times (90, 95, 100, and 105 days after planting), in spring season. The experimental design was randomized blocks with four replications. Each plot consisted of four rows of ten plants each. Ten days after desiccation of plants, the two internal rows of each plot were harvested and the tubers evaluated for yield component, skin roughness, and tone coloration of tuber skin. The data were submitted to analysis of variance and regression. For BRS Clara, a desiccation of the plants should be done earlier to avoid losses in quality of the skin, especially in relation to the roughness of the tubers. The maximum date for desiccation was 100 days after planting of tubers to obtain tubers with skin quality and no further reduction in yield of tubers. For the control cultivar Agata, that presented better tuber appearance than BRS Clara, but lower yield, delaying the desiccation date up to 100 days of planting also seems appropriate, but not due to loss of quality of the skin, but by having reached the maximum yield.

The aim of this research was to study the possibility of decreasing the amount of nitrogen recommended based on the soil analysis for the potato cultivar BRS Ana, considering yield component variables. The experiment was carried out in Haplustox soil, in the experimental field of Embrapa Produtos e Mercado, Canoinhas, Santa Catarina state, Brazil, in the spring season. The treatments consisted of six nitrogen doses applied at planting time (0, 60, 80, 100, 120 and 140 kg ha-1), as ammonium sulphate. The recommended dose of N based on soil analysis was 120 kg ha-1. A randomized complete block design with four replications was used. The tuber yield of each plot was evaluated for yield component variables. Plants of BRS Ana did not respond considerably in yield to nitrogen levels higher than 100 kg ha-1, suggesting that the dose recommended by the soil analysis, 120 kg ha-1, can be reduced in 17%, without loss of yield of tubers. A larger decrease in the amount of nitrogen, however, would cause a reduction in the commercial tuber yield.

The correct definition of the desiccation time, aiming the balance between early maturity and tuber yield is important in the production of potatoes for fresh market. The objective of this study was to investigate the early yield and yield potential of the potato clone CL02-05. The experiment was carried out in the experimental field of Embrapa Produtos e Mercado (Embrapa Products and Market), Canoinhas, Santa Catarina state, Brazil, in the spring season (“rainy” season). Treatments consisted of four desiccation times (80, 90, 100, and 110 days after planting). The experimental design was of randomized complete blocks with three replications. The experimental plot consisted of four 10-plant rows. Ten days after desiccant paraquat application (Gramoxone, 2.5 L/ha), plots were harvested and tubers evaluated for yield component traits. Data were submitted to analysis of variance and of polynomial regression. Mass of marketable tubers of clone CL02-05 desiccated at 90 days after planting (DAP) (20.21 t/ha) was higher than that of ‘Agata’ desiccated at the same time (20.57 t/ha) and similar to ‘Agata’ desiccated at 100 DAP (20.57 t/ha). In the 100 and 110 DAP desiccations the mass of marketable tubers of clone CL02-05 (28.32 and 41.25 t/ha) also was significantly higher than that of ‘Agata’ (20.57 and 21.61 t/ha). The results suggest that, compared to ‘Agata’ which has a mass of marketable tubers optimized close to 100 DAP, the clone CL02-05 reached similar level at 90 DAP, offering greater early yield. The delay in the desiccation, however, enabled significant increases in marketable yield of tubers until at least the 110 DAP, confirming the high yield potential of clone CL02-05. © 2015 Sociedade de Olericultura do Brasil.

The aim of this study was to evaluate the concentrations of indole-3-butyric acid (IBA) in hardwood cuttings of promising grapevine rootstocks for southern Brazil. Plant material was collected from selected plants from the grapevine rootstock collection of EPAGRI Experimental Station, in the city of Videira - SC. The experiment was conducted in a greenhouse during the period from July to October 2013. The experimental design was completely randomized with 20 treatments arranged in a 4x5 factorial scheme, consisting of four rootstocks (VR043-43, Dogridge, Richter 99 and EEV793-5) and five IBA concentrations (0 , 1.000 , 2.000, 3.000 and 4.000 mg L L-1). After 60 days, it was evaluated the rooting percentage, the number, length and the fresh weight of the roots. The use of IBA increased rooting percentage, number, length and fresh weight of roots for all rootstocks. The rootstock VR043-43 showed better root development than the other rootstocks studied. To propagate the four cultivars of grapevine rootstocks evaluated via hardwood cuttings it is recommended the use of IBA at 1000 mg L-1. © 2015, Sociedade Brasileira de Fruticultura.

Although peach breeding programs in Brazil date back to the 1950s all cultivars released were public domain and there has not been any type of plant patent, royalties or similar, until 1997. Since that year all new cultivars may be protected. The main reason for the protection was the need to organize the propagation chain, once nurseries now need the certificate of origin, for all protected cultivars and only the licensee ones can have it. The first peach cultivars protected, in Brazil, were 'BRS Kampai', 'BRS Libra', released in 2009, and 'BRS Regalo' and 'BRS Fascínio', released in 2012. Except 'BRS Libra', all others are table cultivars. All four were obtained by Embrapa Clima Temperado through hybridization, using traditional breeding methods. 'BRS Libra' is the earliest non melting cultivar and is a very low chilling, estimated in less than 150 hours. The cultivars 'BRS Kampai', 'BRS Regalo' and 'BRS Fascínio' produce low acid white flesh fruits, and are being planted under the subtropical climate condition as well as on the temperate zone. 'BRS Kampai' is the earliest one, ripening in mid-November in the south, and at the second half of October in the southeast areas. The harvest of 'BRS Regalo' and 'BRS Fascínio' differs only a few days from each other, being at end of November in the Southeast, and 15 to 20 days later in Southern Brazil. A description of the four cultivars will be provided. Growers from six different Brazilian states have been participating in testing and evaluating the material before releasing, under a nonpropagation agreement. This procedure has been rewarding and gave a lot more confidence on the results. Once a new variety and the mother plants were registered and the protection process had begun, a call for nurseries interested in propagating them was published. © 2015 ISHS.

In recent years, platycarpa peaches have reached high prices due to their good acceptance in the international market. However, the great majority of the released varieties are high chill and do not adapt to Brazilian conditions except on a few microclimes of high altitudes. The cultivar BRS Mandinho is the first peach cultivar of the botanical variety platicarpa, released in Brazil and adapted to subtropical conditions. The plants are vigorous and, in the state of Rio Grande do Sul, the blooming occurs on the second half of July. The fruits are sweet and ripe in November with an average weight of 55.3 g. © 2016, Sociedade Brasileira de Fruticultura. All rights reserved.
