One of the pests that infests the corn crop (Zea mays) in Brazil is the fall armyworm (Spodoptera frugiperda, Lepdoptera: Noctuidae), considered its most important pest because of the significant damage produced. The use of resistant cultivars is an efficient control method. The objective of this work was to evaluate the mechanisms of resistance ... more
There is a lack of information regarding variables that regulate the expression of the yield potential of maize. We studied yield components of maize under different arrangements on field, in the southwest region of the state of Goiás, Brazil. The soil of the experimental area is classified as Typic Orthotic. The experimental design was randomized blocks, in a 9x2 ... more
The corn leafhopper, Dalbulus maidis, is the most important pest of maize (Zea mays) in the Neotropics, due to its efficiency in pathogen transmission and close evolutionary association with the crop. This host specialization has enabled D. maidis to spread with maize, from their center of origin in Mesoamerica to all tropical and ... more
Selection of appropriate genitors in breeding programs increases gains due to the variability found in the divergent groups; this allows quantification of the existing variability, saving time and resources. There are many methods for quantification and evaluation of diversity in population studies, among which we highlight methods that are based on multivariate ... more
