Fig. 2. Likelihood intervals for QTLs associated with ¹³C and other traits detected from 2001 to 2004. Abbreviations: ¹³CG, ¹³C in grain; ¹³CS, ¹³C in shoot; DTH, days to heading; FG/Pan, filled grain number/panicle; GY, grain yield; HI, harvest index; %NG, grain N content; %NL, N content in leaf; %NS, N content in shoot; %NSt, N content in stem; %NStLL, N content in stem + lower leaf; %NTL, N content in top leaf; NUp, N uptake; PH, plant height; PN, panicle number; SLA, specific leaf area; SLN, specific leaf N; TDW, aboveground dry weight; TGW, 1000-grain weight 01 to 04 indicate year. M and MG indicate traits measured at maturity and midgrowth stages, respectively. + and – indicate the positive and negative effect of QTL on the value with alleles from IR69093–41–3–2 (new plant type), respectively.
