Table 3.
QTLs detected for TGW, GL, and GW in ten RH-derived populations in F9 and F10. 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.
