“…Some of these cultivars are considered traditional, such as Solferino, SO4, Kober 5BB and 101-14 Mgt (V. berlandieri x V. riparia), whereas others were more recently introduced, such as Paulsen 1103 and R99 (V. berlandieri x V. rupestris). Although these rootstocks have been recommended due to their resistance to Fusarium oxysporum Schlecht., they are the most susceptible to the main soil pest of this region, the Brazilian ground pearl [Eurhizococcus brasiliensis Hempel (Hemiptera: Margarodidae)] (Botton & Colleta, 2010;Botton et al, 2010).…”

-The objective of this work was to assess the potential of interspecific hybridization of Vitis labruscana and Muscadinia rotundifolia by using artificial cross-pollinations. Microsatellite markers were used to confirm interspecific hybridizations and the identity of the parental genotypes. In crosses in which M. rotundifolia was used as the female parent, no true hybrids were obtained. In the reciprocal crosses, 114 seedlings were identified as true V. labruscana x M. rotundifolia hybrids. Self-pollination occurred in direct and in reciprocal crosses. The crossings between 'Bordo' x 'Carlos', 'Magnolia', 'Regale' and 'Roanoke', and between 'Isabel' x 'Bountiful', 'Carlos', 'Magnolia', 'Regale' and 'Roanoke' were confirmed. The 15 markers evaluated showed that two M. rotundifolia parental genotypes had the same fingerprint profile, indicating a likely planting error. The success of hybridization depends mainly on the species and on the cultivar used as the female parent. Microsatellite markers are efficient to confirm the paternity of interspecific F1 hybrids and to determine the correct identity of M. rotundifolia cultivars.Index terms: Muscadinia rotundifolia, Vitis labruscana, hybrid identification, interspecific crosses, SSRs.

“…M. rotundifolia (Michx.) Small] are resistant to the Brazilian ground pearl (Botton & Colleta, 2010). This species has been classified as having the highest level of resistance to grape pests and disease (Kellow et al, 2002) and has consequently been used in many breeding programs worldwide to create resistant rootstocks.…”

“…In the evaluation of the roots of plants I for the number of ground pearl cysts, an average of 4.2 cysts per plant was reported, a value lower than observed by other authors under field conditions (BOTTON & COLLETA, 2010;BROETTO et al, 2011). Despite the foliar health, the cuttings collected in beds with infestation of ground pearl (I) had, on average, smaller fresh and dry weight, shorter length, and smaller diameter when compared with the cuttings collected from the beds without infestation of ground pearl (Figure 1).…”

“…However, under field conditions, 'Paulsen 1103' plants, within six months of planting, were reported to have two to five cysts per plant and already manifested the symptoms of foliar chlorosis and necrosis (MARCOS BOTTON, verbal report) which are the commonly cited symptoms of ground pearl. According to BOTTON & COLLETA (2010), plants of the rootstock '101-14' (V. riparia ×V. rupestris) with 2 years of high infestation (average of 10 to 60 cysts plant -1 ) had symptoms of infestation and did not survive.…”

“…this practice has satisfactory efficiency only in the case of young plants . The use of more resistant rootstocks against decline has been a way to reduce the problem COLLETA, 2010;DALBÓ et al, 2012). Another measure that has proved effective is preparing the ground for preplanting with the use of trenches or drains, which improves the conditions of drainage and soil aeration (DALBÓ et al, 2007).…”

-the incidence of grapevine decline and dye back is quite severe in grapevine-growing regions of southern Brazil, especially in the midwest of the State of Santa catarina. Field studies on problematic areas identified the presence of the Brazilian ground pearl or margarodes (Eurhizococcus brasiliensis Hempel) and soil fungi (Cylindrocarpon, Fusarium and others) associated with the disease. Soil characteristics such as high clay content and poor aeration were associated with the problem. to evaluate the effect of pre-planting tillage in reducing the incidence of grapevine decline, an experiment was carried out with two rootstocks and three pre-planting tillage (regular plowing, drains, and ridges) in an area where high plant mortality had been previously observed. Pre-planting tillage with the use of ridges along the rows gave the best results with a drastic reduction in the decline incidence. the number of ground pearl cysts was unaffected by pre-planting tillage and did not relate with the incidence of decline and death of plants. Index terms: Vitis sp., rootstocks, black foot disease, ground pearl. CONTROLE DO DECLÍNIO DA VIDEIRA COM O USO DE DRENOS E CAMALHÕESRESUMO -a incidência de declínio e morte de plantas de videira é bastante comum nas regiões vitícolas do Sul do Brasil, especialmente no Vale do Rio do Peixe-Sc. estudos de campo realizados em áreas com grande incidência identificaram a presença de pérola-da-terra (Eurhizococcus brasiliensis Hempel) e fungos de solo (Cylindrocarpon, Fusarium e outros) associados à doença. Observou-se também que características de solo, como alta percentagem de argila e deficiência de aeração, estavam associadas ao problema. Para avaliar o efeito de sistemas de preparo do solo em pré-plantio na redução do declínio e morte de plantas de videira, implantou-se um experimento fatorial com dois porta-enxertos e três sistemas de preparo do solo em pré-plantio (preparo regular e confecção de drenos e camalhões) em área com histórico de alta mortalidade de plantas. A confecção de camalhões na linha de plantio proporcionou os melhores resultados, com redução significativa da incidência de declínio. O número de cistos de pérola-da-terra foi pouco afetado pela confecção de drenos ou de camalhões e não se correlacionou com a incidência de declínio e morte de plantas. Termos para indexação: Vitis sp., porta-enxerto, pérola-da-terra, pé-preto.1
