A phenotypic comparison of yield and related traits in elite commercial corn hybrids resistant to pests
ABSTRACT The development of commercial maize hybrids tolerant to herbicide and resistant to lepidopterans has allowed an important ex pansion of this crop in Brazil. The objective of this study was to field-evaluate the performance of eleven maize hybrids at three different growing locations in Braz...
