Comments about the QTL

Interval length is approximated from illustration in publication

Publication measured nodule number which was used as an indicator of nitrogen fixation, and defined as the number of root nodules counted per plant. See publication for additional details.

Parent_1 was Bossier, Parent_2 was Embrapa 20
