Genetic map of Zucchini × Scallop F2 population (LG8, LG9, LG10, LG11). Linkage map and locations of quantitative trait loci (QTL) whose effects have been verified in the backcross populations associated with vine development, flowering and fruit quality based on 146 F2 plants derived from a Zucchini × Scallop cross. The linkage groups (LGs) have been ordered according to the results obtained in this paper. Group numbers in parenthesis (LGp) correspond to LGs in the map by Gong et al. [44]. The correspondence between the two linkage groups has been determined according to the common SSR markers between maps (underlined). Markers with distorted segregation in F2 are in italics. QTL indicated in light grey, grey or black correspond to flowering, immature of mature fruit traits, respectively. QTL are represented with bars (2-LOD interval) and boxes (1-LOD interval). QTL for qualitative traits are represented with red lines spanning the region between flanking markers significantly associated with the trait at P < 0.05.
