Resistance to Pratylenchus brachyurus in Vitis species population through multi...
Santos,Paulo Ricardo dos; Viana,Alexandre Pio; Gomes,Vicente Martins; Preisigke,Sandra da Costa; Almeida,Odimar Ferreira de; Santos,Eileen AzevedoABSTRACT: Genetically diverse interspecific hybrids of Vitis were selected for resistance to Pratylenchus brachyurus. Three segregating populations with 57 hybrid crosses were evaluated. The parents included Vitis romanetiiC166-043 × 07355-075, 06354-047 × Cereza and 06354-047 × Nocera, selected from the germplasm bank at the University of California, Davis, the United States. The experiment was arranged in a r...
Genome selection in fruit breeding: application to table grapes
Viana,Alexandre Pio; Resende,Marcos Deon Vilela de; Riaz,Summaira; Walker,Michael AndrewABSTRACT Genomic selection (GS) has recently been proposed as a new selection strategy which represents an innovative paradigm in crop improvement, now widely adopted in animal breeding. Genomic selection relies on phenotyping and high-density genotyping of a sufficiently large and representative sample of the target breeding population, so that the majority of loci that regulate a quantitative trait are in lin...
Obtaining interspecific hybrids, and molecular analysis by microsatellite marke...
Schuck,Mariane Ruzza; Biasi,Luiz Antonio; Mariano,Ada Michele; Lipski,Bernardo; Riaz,Summaira; Walker,Michael AndrewThe 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...
