TABLE 3.

Variance component estimates and standard errors for standardized area under disease progress curve (sAUDPC) for the Rp1-D21 lesion phenotype and the mutant:wild type height ratio (Height) for a population consisting of F1 families from a cross between Rp1-D21-H95 heterozygote and 233 lines from the IBM population

	Variance component estimates (standard error) and P-values
Parameter	sAUDPC	P-value	Height (×10−2)	P-value
Environment	0.09 (0.09)a	NS	1.37 (1.46)	NS
Replication within environment	0.01 (0.01)	NS	0.11 (0.11)	NS
Line	0.18 (0.02)	<0.01	0.82 (0.11)	<0.01
Environment by line	0.03 (0.01)	<0.01	0.27 (0.07)	<0.01
Residual	0.06 (0.004)	<0.01	0.71 (0.06)	<0.01

The populations were scored in the field in Clayton, North Carolina, in the summers of 2007 and 2008 (two replications each) and in West Lafayette, Indiana, in 2007 (one replication). NS, not significant.
