Method for enrichment analysis for the QTL terms

Question

[rice.researcher]

I have a micro-array anatomical tissue based co-expressed list of around 80 genes. For each of this gene, I found out the QTL terms associated with it from a genome wide QTL mapped to gene in the organism. For every gene, there are multiple QTL term similar to GO assignment. I would like to know what is the way to do an enrichment analysis for the QTL terms of my co-expressed candidates? The references which I followed use DEGs with certain p-value cutoff but I selected the co-expressed genes based on K-means clustering.
