1Abbreviations: C, the original QTL in Morgans; s, the reduction factor; c, target QTL in Morgans; NTG3, total size of G3 population; NG2, total size of G2 population. NTRP, total number required across G2 and G3 populations; NF2, population size for equivalent QTL width using an F2 design. Assumptions: polygenic effect present; standardized allele substitution effect, d = 0.2; reproductive potential of the G2 generation, n = 50; and confidence level set at (1-α) = 95%
