Evaluating and Mapping Grape Color Using Image-Based Phenotyping

Table 4

QTL significant at a chromosome-wide level using a threshold of for image-derived color values in the GE1025 population (2017: , 2018: ). Parental map specifies the parent from which the QTL originates (maternal: MN1264; paternal: MN1246).
