摘要： Key message QTL mapping identified simply inherited genes and quantitative trait loci underlying morphologically characteristic traits of the Sikkim cucumber, which reveals their genetic basis during crop evolution. The data suggest the Sikkim cucumber as an ecotype of cultivated cucumber not worthy of formal taxonomic recognition. The Sikkim cucumber,Cucumis sativusvar.sikkimensis, is featured with some morphological traits like black spine, brown fruit with fine and heavy netting, as well as large hollow in mature fruit. Despite its establishment as a botanical variety similar to 150 years ago, and its wide use as an important source of disease resistances in cucumber breeding, little is known about its taxonomic status and genetic basis of those characteristic traits. Here we reported QTL mapping with segregating populations derived from two Sikkim-type inbred lines, WI7088D and WI7120, and identification of 48 QTL underlying phenotypic variation for 18 horticulturally important traits. We found that the fruit spine and skin colors in the two populations were controlled by the previously cloned pleiotropicB(black spine) locus. The fruit netting in WI7088D and WI7120 was controlled by the well-knownH(Heavy netting) and a novelRs(Russet skin) locus, which was delimited to a 271-kb region on Chr5 and similar to 736-kb region on Chr1, respectively. A single major-effect QTL was detected for flowering time in each population (ft1.1for WI7088D andft6.2for WI7120). Fifteen, six and five QTL were identified for fruit size, hollow size and flesh thickness variation in the two populations, respectively. No major structural changes were found between the Sikkim and cultivated cucumbers. Except for the rare allele at theRslocus, there seem no private QTL/alleles identified from this study supporting the Sikkim cucumber as an ecotype ofC. sativus, not worthy of formal taxonomic recognition.
