Chromosome Homology in Tetraploid Southern Highbush x Vaccinium elliottii Hy brids
A yellow-leaf seedling marker, r, was used to determine if there was pref er en tial chromosome pairing in a group of tetraploid southern highbush blueberry hybrids. Plants with four copies of r (no copies of R) fail to develop anthocyanins, and cotyledons, hypo co t yls, leaves, stems, and other vegetative tissues have a bright yellow-green color. In the hybrids that were studied, two genomes ...
متن کاملCorrelation between sensory and instrumental measurements of standard and crisp-texture southern highbush blueberries (Vaccinium corymbosum L. interspecific hybrids)
BACKGROUND Fruit texture is a primary selection trait in southern highbush blueberry (SHB) breeding to increase fresh fruit postharvest quality and consumer acceptance. A novel crisp fruit texture has recently been identified among SHB germplasm. In this study, we developed a common set of descriptors that align sensory evaluation of blueberry fruit texture with instrumental measures that could...
متن کاملFruit quality parameters of some southern highbush blueberries (Vaccinium xcorymbosum L.) grown in Andalusia (Spain)
Physical and chemical parameters of fresh berries from three southern highbush (‘O’Neal’, ‘Sharpblue’ and ‘Misty’) blueberry cultivars grown in Huelva (Southwestern Spain) under two production systems were measured and evaluated. ANOVA applied to data yielded significant differences between production systems for mean fruit size and mean fruit fresh weight (P<0.05), although main effects on phy...
متن کاملDemographic source-sink dynamics restrict local adaptation in Elliott's blueberry (Vaccinium elliottii).
In heterogeneous landscapes, divergent selection can favor the evolution of locally adapted ecotypes, especially when interhabitat gene flow is minimal. However, if habitats differ in size or quality, source-sink dynamics can shape evolutionary trajectories. Upland and bottomland forests of the southeastern USA differ in water table depth, light availability, edaphic conditions, and plant commu...
متن کاملChanges in Anthocyanins and Polyphenolics During Juice Processing of Highbush Blueberries (Vaccinium corymbosum L.)
Frozen blueberries (Vaccinium corymbosum L.) were processed into juice and concentrate, and the changes in anthocyanin pigments and polyphenolics (cinnamates, procyanidins, flavonol glycosides) were monitored. While juice yield was 83%, only 32% of the anthocyanins were recovered in single-strength juice. Flavonol, procyanidin and chlorogenic acid recoveries in juice were 35%, 43%, and 53%, res...
