Results for the ANOVA performed for the cell-wall analysis.

Cell-wall component	Midas vs. MG38				Indehiscent vs. highly dehiscent
	M.S.	F1, 4	P	$R_{adj}^2$	M.S.	F1, 22	P	$R_{adj}^2$
Total fiber (NDF)	600.2	98.7	<10−3	0.95	825.15	273.04	<.0001	0.92
Lignin (ADL)	9.5	163.0	<10−3	0.97	115.74	305.35	<.0001	0.93
Hemicellulose (NDF-ADF)	129.3	14.0	0.02	0.72	151.43	140.95	<.0001	0.86
Cellulose (ADF-ADL)	100.9	134.1	<10−3	0.96	32.05	14.64	0.0009	0.37

ANOVA was applied to the following comparisons: Parental lines MG38 (dehiscent) vs. MIDAS (indehiscent); and two groups of 12 introgression lines, one completely indehiscent vs. one highly dehiscent (i.e., with percentage shattering pods >65% of MG38). M.S., Mean Square; F_x/y, F ratio with x and y degrees of freedom for the numerator and denominator, respectively. $R_{adj}^{\mathit{\text{2}}}$, adjusted R²; P, significance level.

NDF, neutral detergent fiber; ADL, acid detergent lignin; ADF, acid detergent fiber.
