1. Potential of forage and grain yield of maize genotypes in the Brazilian semiarid region
ABSTRACT Maize is importance in the semiarid region due to its forage potential. However, the large number of hybrids on the market hampers the selection of the hybrid by the producer. Given the above, the objective of this paper is to identify genotypes with productive potential for forage and grain production according to the characteristics of the semiari

2. Inbreeding depression and genetic variability of populations for green maize production
ABSTRACT The production of green maize is considerable important for various regions of Brazil. It is vital that breeding programs of public institutions seek to meet the needs of this market sector, which has a relevant social role, mainly on small properties. The aim of this study was to estimate the inbreeding depression and the genetic components (m + a

3. Combining abilities analysis for ear rot resistance in popcorn hybrids development
ABSTRACT Ear rot caused by fungi of genus Fusarium (FER) is one of the potentially harmful diseases to grain quality in maize. Given the capacity to produce mycotoxins, FER presents a risk to food safety. This study sought to identify parents and indicate hybrids of popcorn with a higher level of resistance to the incidence and severity of FER. Hybrids were

4. The usefulness of GGE biplot methodology for line × tester data of maize inbred lines
ABSTRACT The genotype + genotype × environment (GGE) biplot methodology has the potential to determine combining ability effects, identify efficient testers, and distinct heterotic groups in a line × tester study. However, it has not been adequately applied for such analysis. Therefore, this study was done to assess the combining ability of some maize inbr

5. Resistance of maize landraces from Brazil to fall armyworm (Lepidoptera: Noctuidae) in the winter and summer seasons
ABSTRACT The fall armyworm (Spodoptera frugiperda) is a major maize (Zea mays L.) pest in Brazil, whose larvae cause losses from plant emergence to harvesting stage. This pest has been controlled almost exclusively with chemical insecticides and Bt plants (transgenics); however, resistance evolution has been detected to these two control tactics. Therefore,

6. Partially inbred maize lines in topcrosses and hybrid performance
ABSTRACT In plant breeding programs, the selection of potential progenies in early generations of inbreeding is an essential step. Considering that, the adoption of topcrosses helps the breeder in the selection, this study aimed to verify the potential of S2 strains for synthesis of synthetic varieties and to obtain experimental information on yield and agro

7. Performance, carcass characteristics and ingestive behavior of steers fed with silages of different maize hybrids
RESUMO O objetivo deste trabalho foi avaliar desempenho, características da carcaça e comportamento ingestivo de novilhos terminados em confinamento alimentados com silagens dos híbridos de milho: Maximus VIP3, Defender VIP e Feroz VIP. O experimento teve duração de 112 dias, sendo quatro pesagens a cada 28 dias. As dietas experimentais foram formuladas

8. Influência da qualidade micotoxicológica e nutricional de híbridos de milho no custo da ração de frangos de corte
RESUMO Objetivou-se avaliar as variáveis micotoxicológicas e nutricionais de híbridos de milho com diferentes características que influenciam no custo da ração para frangos de corte. Foram avaliados 26 híbridos de milho geneticamente modificados nas safrinhas de 2016 e 2017, com diferentes germoplasmas, textura de endosperma e duração do ciclo. Nos

9. Reaction of maize hybrids to Northern corn leaf blight and common rust, and chemical control of Northern corn leaf blight
RESUMO: A helmintosporiose e a ferrugem comum estão entre as principais doenças fúngicas que afetam a produção do milho. Os objetivos desse trabalho foram avaliar a suscetibilidade de dez híbridos de milho a helmintosporiose e a ferrugem comum e verificar a eficiência de fungicidas no controle de Exserohilum turcicum. No primeiro experimento utilizara

10. CONTROL OF GLYPHOSATE-RESISTANT VOLUNTEER MAIZE USING ACCase INHIBITING HERBICIDES
RESUMO O controle das plantas voluntárias foi dificultado com o advento das culturas geneticamente modificadas para tolerância ao herbicida glyphosate, exigindo novas recomendações técnicas para manejo. Este trabalho foi desenvolvido com o objetivo de avaliar alternativas para controle químico de plantas voluntárias de milho resistentes ao glyphosate,

11. YIELD AND BIOMETRIC CHARACTERISTICS OF MAIZE SUBMITTED TO PLANT POPULATION AND TRINEXAPAC-ETHYL DOSES
RESUMO O uso de biorreguladores na agricultura pode alterar a morfologia das plantas de milho, aumentando a produtividade da cultura pela possibilidade do incremento populacional. O trabalho objetivou avaliar os efeitos de populações de plantas associadas às doses de trinexapac-ethyl (TE) sobre as características biométricas da parte aérea e a produtiv

12. Leaf application of chitosan and physiological evaluation of maize hybrids contrasting for drought tolerance under water restriction
Resumo As regiões que cultivam milho como cultura principal ainda não possuem tecnologias adequadas para mensurar as perdas na produtividade decorrentes na disponibilidade irregular de água. O objetivo desse estudo foi avaliar as características fisiológicas de híbridos de milho tolerante (DKB 390) e sensível (BRS1030) à seca, no estádio de crescime
