  • The QTL are designed with the serial numbers of chromosome and marker interval; ao (do) is the embryo additive (dominance) effect of one QTL; Embedded Image Embedded Image Embedded Image and Embedded Image are the interaction effects of the embryo additive and the embryo dominance with the first (subscript 1) and the second (subscript 2) environments, respectively; aaoo, aamo, and aaom are the embryo additive–additive epistatic effect, the maternal–embryo additive–additive epistatic effect, and the embryo–embryo additive–additive epistatic effect, respectively; Embedded Image Embedded Image Embedded Image Embedded Image Embedded Image and Embedded Image are the embryo additive–additive × environment interaction effects in the first (subscript 1) and the second (subscript 2) environments, the epistasis × environment interaction effects between maternal additive and embryo additive in the first (subscript 1) and the second (subscript 2) environments, and the epistasis × environment interaction effects between embryo additive and maternal additive in the first (subscript 1) and the second (subscript 2) environments, respectively; * and ** indicate reaching significance at a level of 0.05 and 0.01, respectively. Chr., Pos., am, Embedded Image Embedded Image aamm, Embedded Image and Embedded Image have the same definitions as those in Table 1, Table 2, Table 3 and Table 4.
