Table 6 QTLs detected for TGW, GL, and GW in two RH-derived populations in F11 and two backcross populations in BC3F5. TGW, 1000-grain weight (g); GL, grain length (mm); GW, grain width (mm); A, additive effect of replacing a HHZ allele with a JZ1560 allele; D, dominance effect; R2, proportion of phenotypic variance explained by the QTL effect; ns, no significance.
