a Position is reference to the Rice Genome Annotation Project Release 7 (RGAP 7 of Nipponbare). b P = 0.01, Wald value = 11.34; p = 0.05, Wald value = 7.81. c The genetic effects indicate that the introgression of the donors resulted in the segregation distortion loci. ∗ Indicates the significant difference at P < 0.05.
