TABLE 1.

Variance components estimates and respective standard errors, obtained with the fitting of the univariate linear mixed model for SLT in 2014, 2015, and 2016, and the P-value of the likelihood ratio test for variance components (testing the null hypothesis if the variance component is zero).

Year	Variance component	Estimate (SE)	P
2014	Genotypic	0.664 (0.108)	<0.001
	Incomplete block within complete block	6.157 (0.970)	<0.001
	Leaf (within plot)	7.034 (0.176)	<0.001
	Error	0.606 (0.005)
2015	Genotypic	0.725 (0.104)	<0.001
	Incomplete block within complete block	6.910 (1.081)	<0.001
	Leaf (within plot)	5.609 (0.140)	<0.001
	Error	0.441 (0.003)
2016	Genotypic	0.766 (0.115)	<0.001
	Incomplete block within complete block	4.308 (0.687)	<0.001
	Leaf (within plot)	6.623 (0.165)	<0.001
	Error	0.365 (0.003)

For the fixed-effects factor of the experimental design (complete block), the effect was significant in the 3 years (P < 0.01).
