The numbers at the left of the slash (“/”) are mean squares or heritability for the unconditional phenotype of RILs, and the numbers at the right indicate the conditional phenotype of RILs.

^*P ≤ 0.05 and

^**P ≤ 0.01.

S1–S5 are as shown in Table 1. S|S-1 indicates the time interval from S-1 to S.
