This maize genetic map was mainly based on expressed sequences, and it incorporates data from four segregating populations. The final integrated map included 275 loci and covered 1765 cM. Three recombinant inbred line populations were derived from the nonreciprocal crosses between three inbred lines. Among three inbred lines, F2 is a French early flint line, F252 is an American early dent line, and Io is a line from the Iodent group. The first RI population was derived from the cross between Io and F2, and has 145 RI lines. The second was derived from the cross between F252 and F2, with 129 RI line. The third was derived from the cross between Io and F252, with 152 RI lines. Another F2 population derived from the cross between Io and F2 with 95 individuals was also used to generate the composite map. |
