  • a GPC: grain protein content, BMT: bake mixing time, BA: baking absorption, BLV: bread loaf volume, CBCL: crumb color, CTCL: crust color, FE: flour extraction rate, MIXOPA: the general mixograph pattern, MELS: mixograph envelope left slope, MERS: mixograph envelope right slope, MMLPT: mixograph MID line peak time, MMLPV: mixograph MID line peak value, MMLTV: mixograph MID line time * value, MMLPW: mixograph MID line peak width, MMLPI: mixograph MID line peak integral; DO: dough character.

  • b *A significant difference between parental lines at P < 0.05.

  • c Standard deviation.

  • d Range is estimated based on BLUP values.

  • e The second quartile or median.

  • f broad-sense heritability coefficient according to Holland (2003).

  • g Class of broad-sense heritability according to Hallauer and Miranda (1988), VH = very high = H2 > 0.70, HI = high = 0.50 < H2 < 0.70, M = medium = 0.30 < H2 < 0.50, L = low = H2 <0.30.
