摘 要:Deciphering the genetic control of grape berry traits is crucial for optimizing yield,fruit quality,and consumer *** this study,an association panel of 179 grape genotypes comprising a mixture of ancient cultivars,landraces,and modern varieties collected worldwide were genotyped with genotyping-by-sequencing using a genome-wide association approach based on 32,311 single-nucleotide polymorphism(SNP)***-wide efficient mixed-model association was selected as the optimal statistical model based on the results of known control loci of grape berry color *** of the associated SNPs identified in this study were in accordance with the previous QTL analyses using biparental *** grape skin color locus was found to be associated with a mybA transcription factor on chromosome *** strong and distinct association signals associated with berry development periods were found on chromosome *** candidate genes of the interval were highlighted as receptor-like protein *** berry weight,significant association loci were identified on chromosome 18,as previously known,and on chromosome 19 and chromosome 17,as newly *** flesh texture was newly located on chromosome 16;candidate genes in the interval were related to *** flavor was determined on chromosome *** regions were further investigated to reveal candidate *** this work,we identified interesting genetic determinants of grape berry-related *** identification of the markers closely associated with these berry traits may be useful for grape molecular breeding.
