Non-Destructive Monitoring of Foliar Fungicide Efficacy with Hyperspectral Sensing in Grapevine Open
Frequent fungicide applications are required to manage grapevine powdery mildew ( Erysiphe necator). However, this practice is costly and has led to widespread fungicide resistance. A method of monitoring in-field fungicide efficacy could …

Discovery and genome-guided mapping of <i>REN12</i> from <i>Vitis amurensis</i>, conferring strong, rapid resistance to grapevine powdery mildew Open
Powdery mildew resistance genes restrict infection attempts at different stages of pathogenesis. Here, a strong and rapid powdery mildew resistance phenotype was discovered from Vitis amurensis ‘PI 588631’ that rapidly stopped over 97% of …

High throughput saliency-based quantification of grape powdery mildew at the microscopic level for disease resistance breeding Open
Imaging-based high throughput phenotyping (HTP) systems have demonstrated promising solutions to enhance genetic understanding of grapevine powdery mildew (PM) resistance and have accelerated PM-resistant cultivar breeding. The accuracy an…

Fine Mapping of Leaf Trichome Density Revealed a 747-kb Region on Chromosome 1 in Cold-Hardy Hybrid Wine Grape Populations Open
Segregation for leaf trichome density was observed in a cold-hardy hybrid grape population GE1025 ( N = ∼125, MN1264 × MN1246) that was previously used to detect a quantitative trait locus (QTL) underlying foliar phylloxera resistance on c…

Image-based Phenotyping Identifies Quantitative Trait Loci for Cluster Compactness in Grape Open
Grape ( Vitis vinifera ) cluster compactness is an important trait due to its effect on disease susceptibility, but visual evaluation of compactness relies on human judgement and an ordinal scale that is not appropriate for all populations…

High-resolution grape cluster images and color-based segmentations for population GE1025 in 2017 and 2018 Open
Two years (2017, 2018) of images are included. RAW (.NEFF) files were those originally captured; .TIFF files are those which were color-corrected and used for segmentation; .PNG files are output segmented images. More information on the im…

Mapping quantitative height traits in sorghum across growth stages Open
Heterosis, the relative increase in fitness of a hybrid offspring as compared to its parents, has contributed significantly to gains made through plant breeding. This phenomenon is most often observed in tall hybrid plants with increased v…
