Comparison of Two Inoculation Methods for Evaluating Maize for Resistance to Aspergillus flavus Infection and Aflatoxin Accumulation

Table 1

Geometric means for aflatoxin accumulation in 10 maize single cross hybrids grown at Mississippi State in 2011 and 2012 following inoculation with A. flavus using the side-needle technique or infected wheat kernels.

Data were transformed (ln(y + 1), where y = aflatoxin concentration) before analysis. Geometric means were calculated by converting logarithmic means back to the original units of measure. Means in a column followed by the same letter do not differ (Fisher’s Protected LSD, P = 05).
