Table 2. Comparison of means and variance of disease severity scores from two F₁ mapping populations (PIO and AFX) inoculated with Verticillium alfalfae.

Population	No.*	Mean	Standard error	Levene's test for equality of variances	T-test for equality of means#
PIO	188	2.75	0.08	p = 0.513	p = 0.08
AFX	164	2.54	0.08

Note: “*”, number of individuals in each population. “#”, means of disease severity scores.
