Multiple localization analysis of the major QTL sfw 2.2 for controlling single fruit weight traits in melon based on SLAF sequencing

Cucumis melo, is an annual dicotyledonous trailing herb. It is fruity, cool and refreshing to eat and widely loved by consumers worldwide. The single fruit weight is an important factor affecting the yield, and thus the income and economic benefits, of melon crops. In the present research, to identify the main QTLs (quantitative trait locus) controlling the single fruit weight of melon and thereby identify candidate genes controlling this trait, specific-locus amplified fragment sequencing analysis was performed on the offspring of female 1244 plants crossed with male MS-5 plants.
