  1. aof all expressed genes.
  2. bof non-additively expressed genes.
  3. The up- or down-regulated numbers of the nonadditively expressed genes.
  4. The nonadditively expressed genes can be divided into six categories based on their expression: F represented the synthetic allohexaploid lines; P, paternal lines; and M, maternal lines. High-paternal dominance, F = P, F > M, P > M; high-maternal dominance, F = M, F > P, M > P; low-paternal dominance, F = P, F < M, P < M; low-maternal dominance, F = M, F < P, M < P; over-dominance, F > P and F > M; under-dominance, F < P and F < M.
