The seed coat colour is an important contributor to the quality of oilseed,which is determined by the content of phenolic compounds cyanidin and procyanidins that is synthesized via the flavonoid pathway,a core branch pathway of phenylpropanoid pathway.Here,in order to determine the upstream regulatory network of the flavonoid biosynthesis pathway genes families,we performed an eQTL analysis of 94 recombinant inbred lines (RILs) from a cross between the female parent GH06 and male parent ZY821,using the transcript-level variation in seeds of 30 days after flower (DAF).
