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

Table 2

Aspergillus flavus/maize ratio for 10 maize single cross hybrids following inoculation with A. flavus using the side needle technique or infected wheat in 2011 and 2012.

Data were transformed (ln(y + 1), where y = ratio of A. flavus/maize) before statistical analysis. Geometric means were calculated by converting logarithmic means back to original units of measure. Means in a column followed by the same letter do not differ (Fisher’s Protected LSD, P = 0.05).
