Combined analysis of variance for Sclerotinia basal stalk rot disease incidence scores among individuals of the HA 89/Helianthus praecox AB-QTL population tested at Carrington, ND during 2017–2018.

Component	df	Variance estimate	Confidence limit (0.05)		F/Z value†	p > F/Z
			Lower	Upper
Genotype (Gen)	173	${\sigma }_g^2$ = 90.68	66.32	131.53	2.90	<0.0001
Environment (Env)	1	${\sigma }_l^2$ = 43.48	8.23	96,733	0.67	0.2507
Rep (Env)	4	${\sigma }_r^2$ = 5.74	1.76	101.68	1.15	0.1254
Gen × Env	172	${\sigma }_{gl}^2$ = 21.84	9.93	81.03	2.23	0.0128
Error	689	${\sigma }_e^2$ = 219.51	198.06	244.68

Coefficient of variations (CV) for DI in the field = 86.9%.

^†In the PROC MIXED model, genotypes were considered fixed and, therefore, subject to F-test (values in bold). F, Fisher’s F-test statistic; Z, Z-test statistic.
