Dent populations are named D1–D6 and flint populations are named F1–F6, followed by the names of the two founder lines. The number of hybrids derived from each parental population is indicated (“Total no. of hybrids”) as well as the number of lines that contributed to hybrids (“Total no. of lines”).
