Abstract: To explore the inheritance and genetic loci of melon rind color, the yellow-rind line B432 and green-rind lines B168 and B421 were used as parent to construct six generations of genetic population (P1, P2, F1, F2, BC1P1, BC1P2) to analyze the inheritance of melon rind color. In addition, the BSA-seq and whole genome resequencing technology were used to locate the genetic loci responsible for melon rind color. The results show that the melon rind color is controlled by two genes, of which green has a dominant epistatic effect on white and white is dominant to yellow. The rind color related genes are mapped to the 0.02-5.7 Mb and 0.08- 9.5 Mb intervals of chromosome 4 and chromosome 10, respectively. This experiment preliminarily elucidates the genetic mechanism and the location of the genes controlling the rind color of melon, and could provide a basis for the subsequent fine-grained gene mapping and molecular marker-assisted selection of melon rind color.
