ABSTRACT: This study aimed
to assess the resistance of grain from two varieties of maize landraces in
initial breeding in Bom Jesus-PI, with respect to S. zeamais attack. Seeds of two maize landraces were used: purple straw maize from two different origins (São Paulo (SP) and
Espírito Santo (ES)) and Peruvian purple
maize. The experimental design
was completely randomized with four replications. The
data for each response variable were subjected to analysis of variance,
applying the F-test (p ≤ 0.05), and when significant differences were found,
there was a comparison of means by Tukey test (p ≤ 0.05). The statistical
analyses were performed using the software SAS®. In a free-choice
test and bioassay for evaluating the nutritional index (no choice test), maize
varieties differed significantly by Tukey test and the cultivar SP was
considered resistant, while the cultivars purple and ES were considered
susceptible.
