Fine Mapping of Leaf Trichome Density Revealed a 747-kb Region on Chromosome 1 in Cold-Hardy Hybrid Wine Grape Populations

Segregation for leaf trichome density was noticed in a cold-hardy hybrid grape inhabitants GE1025 (N = ∼125, MN1264 × MN1246) that was beforehand used to detect a quantitative trait locus (QTL) underlying foliar phylloxera resistance on chromosome 14. Our speculation was that prime trichome density was related to resistance to phylloxera. Existing literature discovered trichome density QTL on
