  1. *Differentially expressed genes (based on ANOVA FDR < 0.05)
  2. **filters: 1) at least one genotype avg signal > 50; fold-change of at least 1.2 between any two genotypes (parent1-parent2 or parent1-hybrid or parent2-hybrid comparisons)
  3. ***based on two-tailed t-test between midparent and hybrid (p < 0.05)
  4. ****based on two-tailed t-tests (p < 0.05); hybrid must be significantly different than midparent and not significantly different from either high or low parent
  5. *****AHP: above high parent; based on one-tailed t-test between high parent and hybrid (p < 0.05) and d/a > 1
  6. ******BLP: below low parent; based on one-tailed t-test between low parent and hybrid (p < 0.05) and d/a < -1
