-
Quality traits measured in wholemeal maize flour from each of the 132 maize inbred lines evaluated in two growing seasons (2011 and 2012)
- aTraits: PR – Protein, in %; FI – Fiber, in %; FT – Fat, in %; STL – Starch, in %; SIZEL – Mean particle size, in μm; PV – Peak (maximum) viscosity, in cP; TV – Trough (minimum) viscosity, in cP; FV – Final viscosity, in cP; BD_SqRt – Breakdown, in cP; SB1 – Setback from trough viscosity, in cP; SB2 – Setback from peak viscosity, in cP
-
b
Variance attributed to the individual terms of the statistical model: σ
2
p
corresponds to the phenotypic variance; σ
2
g
corresponds to the genotypic variance; σ
2
g×y
corresponds to the interaction between inbred lines and growing seasons variance; σ
2
error
(%) corresponds to the variance attributed to the block, row, column, and residual terms which altogether compose the error variance
-
c
h
2
=broad-sense heritability estimates obtained by fitting inbred lines as random terms in the statistical model across growing seasons
-
d
Traits values obtained from lyophilized flour
-
e
Breakdown values were squared-root transformed
