Table 2 The 90% credible interval for causal structural coefficients in the three causal structures
λPH→FTA(0.30, 0.52)NA(0.30, 0.55)
λPH→PN(-0.21, -0.02)(-0.20, -0.01)NA
λFTA→PHNA(0.22, 0.44)NA
λPN→PHNANA(-0.27, -0.05)
  • PH, FTA, and PN represent traits plant height, flowering time in Arkansas, panicle number per plant, respectively. λab represents the causal effects of trait a on trait b. NA denotes structural coefficients those do not exist in the causal structure.
