Additional file 2: of Genetic dissection of yield-related traits and mid-parent heterosis for those traits in maize (Zea mays L.)

Figure S2. Phenotypic variance explained (PVE) by QTL and epistasis interaction (EPI, digenic interaction) effects for nine yield-related traits in the RILs, IF2 population and the MPH dataset. The total PVE for QTL and epistasis was estimated on ICIM-ADD and ICIM-EPI, respectively. ICIM, inclusive composite interval mapping. RIL, recombinant inbred line. IF2, immortalized F2. MPH, mid-parent heterosis. EWPE, ear weight per ear; CWPE, cob weight per ear; EL, ear length; ED, ear diameter; CD, cob diameter; RN, row number; KNPR, kernel number per ear; KWPE, kernel weight per ear; RKP, rate of kernel production.
