RILs | 254 | HB = RIL − MP, where MP = (Lemont + Teqing)/2 |
LTBCF_{1} | 172 | H_{MP} = F_{1} − MP, where MP = (RIL + Lemont)/2 |
TQBCF_{1} | 177 | H_{MP} = F_{1} − MP, where MP = (RIL + Teqing)/2 |
Z413BCF_{1} | 192 | H_{MP} = F_{1} − MP, where MP = (RIL + Z413)/2 |

RIL, recombinant inbred line; H_{MP}, heterosis.
↵^{a} LTBCF_{1} and TQBCF_{1}s are two BCF_{1} populations obtained by crossing the RILs with the parents, Lemont (LT) and Teqing (TQ); while Z413F_{1}s and IR64F_{1}s are two testcross F_{1} populations obtained by crossing the RILs with the testers, Zhong 413 (Z413) and IR64.
↵^{b} HB and H_{MP} are estimates of hybrid breakdown and midparental heterosis. F_{1}'s are mean trait values of individual BC or testcross hybrids while RIL is the corresponding female RIL parent for each of the BC or testcross hybrids.
