The invention discloses a breeding method for identifying the color of colored rape petals based on spectral characteristics, which comprises the following steps: selecting petals of a colored rape single plant, putting the petals into a centrifugal tube filled with an extracting agent, sealing, and soaking in a dark place; uniformly mixing the soak solution, taking 1mL of the soak solution, carrying out full-wave band scanning, and recording peak values of all wave bands; according to the spectrum characteristics of the mottle pigment, naming the colored rape, and recording; the method comprises the following steps: listing named colored rape as a female parent, selecting yellow rape flowers as a male parent, and hybridizing to obtain F0 seeds; the F0 seeds are sown, excellent single plant main inflorescences are selected for seed reserving to obtain Fl seeds, and F1 seeds are sown in a mixed mode; and carrying out multi-generation selfing separation until strains with the same target flower color of the who
