Table 1.
Mean squares from ANOVA-GLM for yield-related traits of the three homozygous durum wheat NIRLs (HOM+) and of their 7AgL non-carrier controls (HOM−) determined for whole plant in (A) 2009 and 2010, (B) 2010 only, and (C) for the main shoot in 2009 and 2010
GY, grain yield per plant (g); SN, seed number per plant; TTN, total productive tiller number; TTH, tiller number per plant at heading; TKW, thousand-kernel weight (g); GYE, grain yield per ear (g); SNE, seed number per ear; TH, plant height (mm); DTH, days to heading; B, biomass per plant (g); HI, harvest index; FLW, flag leaf width (cm); FLL, flag leaf length (cm); FLA, flag leaf area (cm2); FL-1W, flag leaf-1 width (cm); FL-1L, flag leaf-1 length (cm); FL-1A, flag leaf-1 area (cm2); EL1, ear length (cm); SNE1, seed number per main shoot ear; SPNE1, spikelet number per main shoot ear; SPS1, seeds per spikelet; GYE1, grain yield per main shoot ear (g); *, **, *** indicate significant F values at P <0.05, 0.01, and 0.001, respectively.
