Fruit quality traits play a significant role in consumer preferences and consumption in blueberry(Vaccinium corymbosum L).The objectives of this study were to construct a high-density linkage map and to identify the underlying genetic basis of fruit quality traits in blueberry.A total of 287 F_(1) individuals derived from a cross between two southern highbush blueberry cultivars,‘Reveille’and‘Arlen’,were phenotyped over three years(2016–2018)for fruit quality-related traits,including titratable acidity,pH,total soluble solids,and fruit weight.A high-density linkage map was constructed using 17k single nucleotide polymorphisms *** linkage map spanned a total of 1397 cM with an average inter-loci distance of 0.08 *** quantitative trait loci interval mapping based on the hidden Markov model identified 18 loci for fruit quality traits,including seven loci for fruit weight,three loci for titratable acidity,five loci for pH,and three loci for total soluble *** of these loci were detected in more than one *** loci explained phenotypic variance ranging from 7 to 28% for titratable acidity and total soluble solid,and 8-13% for ***,the loci identified for fruit weight did not explain more than 10%of the phenotypic *** also reported the association between fruit quality traits and metabolites detected by Proton nuclear magnetic resonance analysis directly responsible for these fruit quality *** acids,citric acid,and quinic acid were significantly(P<0.05)and positively correlated with titratable *** molecules showed a strong and positive correlation with total soluble ***,the study dissected the genetic basis of fruit quality traits and established an association between these fruit quality traits and metabolites.

Effect of Phenolic Compounds on the Growth and L-Malic Acid Metabolism of Oenococcus oeni

The effect of some phenolic compounds recurrent in wines on technological features of Oenococcus oeni was studied in order to individuate those strains to be utilized as starter in the deacidification of aged red wines. For this purpose, the growth and the L-malic acid metabolism of 100O. oeni strains, previously isolated from different wines, was assayed in a synthetic medium added with ethanol, malic acid and phenol carboxylic （gallic, caffeic, p-coumaric and ferulic） acids or flavonoids （catechin and quercetin） at different concentrations. Results evidenced a different sensitivity of strains to each assayed compound. All the compounds restrained or stimulated the growth of 57 and 11 strains respectively, while no effect was detected on 6 strains. The remaining 26 strains showed a different behaviour： all were restrained by ferulic acid and stimulated by gallic acid and catechin. As for caffeic acid, 17 out of 26 strains were restrained, while 9 strains were stimulated. The main result obtained in this study was the establishment of a relationship between the effect of phenolic compounds on the O. oeni growth and the behaviour of the malolactic fermentation. This study may enrich the selection criteria of strains for the deacidification of aged red wines.
