Identifying Breeding Priorities for Blueberry Flavor Using Biochemical, Sensory, and Genotype by Environment Analyses

摘要: Breeding for a subjective goal such as flavor is challenging, many blueberry cultivars are grown worldwide, and identifying breeding targets relating to biochemistry that have high degree of genetic control low environmental variability priorities. A variety biochemical compounds physical characters induce the sensory responses taste, olfaction, somatosensation, all which interact create what perceived flavor. The this study was identify with larger versus component regulating their expression over an array cultivars, locations, years. Over course three years, consumer panelists rated overall liking, texture, sweetness, sourness, intensity 19 southern highbush (Vaccinium corymbosum hybrids) genotypes in 30 panels. Significant positive correlations liking fruit (P<0.001) were found sweetness (R2 = 0.70), texture 0.68), 0.63). Sourness had significantly negative relationship 0.55). between also linear 0.73, P<0.0001) demonstrating interaction olfaction somatosensation. Partial least squares analysis used sugars, acids, volatile contributing intensities, revealed strong effects fructose, pH, several upon parameters measured. To assess feasibility components, year conducted compare influences on biochemistry. Panelists could discern genotypic variation affecting favor blueberries, β-caryophyllene oxide 2-heptanone, sufficiently genetically controlled allocating resources worthwhile.
