Fig. 3. Effect of added puroindolines on flour and break flour yields. (A) Plot showing positive correlation between flour yield and single kernel characterization system (SKCS) for all 20 lines. (B) Plot showing negative correlation between break flour yield and SKCS for all 20 lines. HC = hard wheat controls, SC = soft wheat control (not included in correlation), A = pina-D1a transformants, and A + B, B = pina-D1a + pinb-D1b, pinb-D1b transformants. Data points are based on means of two environments.
