↵a The three DNA extraction methods were described in detail in Materials and Methods. Data were analyzed by using indicator variables in the general linear model as described in the text.

↵b Probability of a greater

*F*value (*P*values) when testing whether the extraction procedure had an effect on the DNA yields as described by SAS type III sums of squares.*P*values greater than 0.05 were considered significant. NSD, values that were not significantly different (*P*values of 0.18 to 0.95).
