1. Genetic diversity and correlation network approach on cotton genotypes in southern of Minas Gerais
ABSTRACT The cultivation of Cotton (Gossypium hirsutum) is trending in an upward expansion at Minas Gerais state, Brazil. Due this growth, the breeding program has been demanded for the knowledge about the genetic diversity and correlation between morpho-agronomic traits, to start interesting crosses. The objective of this work was to study the genetic diver

2. PhenoRoots: an inexpensive non-invasive phenotyping system to assess the variability of the root system architecture
ABSTRACT: The root system architecture (RSA) of plants and its functioning play a fundamental role in a number of plant growth mechanisms including water and nutrient uptake. Optimization of the RSA is important for stable and increased plant productivity under adverse conditions. Despite its great importance, studying the RSA is notoriously laborious becaus

3. Association of Mechanical and Chemical Methods for Cotton Stalk Destruction
RESUMO: A destruição de soqueiras do algodoeiro após a colheita é uma medida profilática que visa reduzir a população de insetos-praga e de inóculos de doenças que podem permanecer alojados nos restos culturais e plantas de algodoeiro remanescentes. O objetivo deste trabalho foi avaliar métodos integrados de manejo das soqueiras, conciliando contro

4. Behavioral aspects of Helicoverpa armigera in the cotton vegetative phase1
RESUMO Helicoverpa armigera (Hübner) faz parte de um importante complexo de insetos-pragas que atacam a cultura do algodoeiro. Objetivou-se identificar partes da planta preferenciais para a oviposição das mariposas, bem como os comportamentos de movimentação e alimentação das lagartas, na fase vegetativa da cultivar de algodão BRS 369 RF.

5. Performance of colored cotton under irrigation water salinity and organic matter dosages
Resumo Este trabalho foi realizado com o objetivo de avaliar o desenvolvimento do algodoeiro colorido, submetido a diferentes níveis de salinidade da água de irrigação e doses de matéria orgânica proveniente de esterco bovino curtido. O delineamento experimental utilizado foi inteiramente casualizado em esquema fatorial 4 x 4, com 3 repetições, total

6. Does the Introgression of Bt Gene Affect Physiological Cotton Response to Water Deficit?
RESUMO: O déficit hídrico pode afetar a expressão de proteínas que promovem o controle de lepidópteras no algodoeiro. Entretanto, não é conhecida a resposta de cultivares de algodão Bt e convencionais ao déficit hídrico, o que poderia afetar o potencial de competição com plantas daninhas. O objetivo deste trabalho foi avaliar a resposta de cultiv

7. Residual Activity of Diclosulam Applied to Soybean on Cotton Crop in Succession
RESUMO: A aplicação de herbicidas alternativos ao glyphosate pode afetar a cultura em sucessão devido à persistência no solo. O objetivo deste trabalho foi avaliar a atividade residual do diclosulam aplicado em pré-emergência na cultura da soja sobre o algodoeiro em sucessão. O delineamento experimental foi em blocos casualizados com cinco repetiçõ

8. Genetic gains in agronomic and technological traits of elite cotton genotypes
ABSTRACT The objective of this work was to estimate the predicted genetic gains with the simultaneous selection of agronomic and technological traits from elite cotton lines using selection indexes. Data from the evaluation of 36 elite lines were evaluated in three trials located in Apodi-RN in 2013 and 2014 and Santa Helena, GO, Brazil in 2013, in a randomi

9. Diallel analysis in cotton (Gossypium hirsutum L.) for water stress tolerance
Abstract Information about combining ability is important in determining breeding strategies. The objective of this study was to estimate the general (GCA) and specific (SCA) combining abilities among twenty cotton hybrid combinations submitted to water stress, based on agronomic traits. The trails were carried out in semiarid environment (Barbalha, CE), dur

10. Nutrient Uptake by High-Yielding Cotton Crop in Brazil
ABSTRACT: Determining nutrient uptake and accumulation rates by cotton crops is important to define management strategies, especially for transgenic varieties, which are cultivated using high-technology approaches that require substantial investment to maximize yield. Currently in Brazil, the states of Bahia and Mato Grosso are responsible for 84.4 % of the

11. The behavior of Aphis gossypii and Aphis craccivora (Hemiptera: Aphididae) and of their predator Cycloneda sanguinea (Coleoptera: Coccinellidae) in cotton-cowpea intercropping systems
ABSTRACT The intercropping is an important cultural practice commonly used in pest management. It is based on the principle that increased plant diversity in the agro-ecosystem can lead to reductions of pest populations in the crop. The current study aimed to assess the impact the colored fiber cotton-cowpea intercropped systems on Aphis gossypii and Aphis c

12. Effects of temperature on the feeding behavior of Alabama argillacea (Hübner) (Lepidoptera: Noctuidae) on Bt and non-Bt cotton plants
ABSTRACT The host acceptance behavior and environmental factors as temperature affect the feeding behavior of Lepidoptera pests. Thus, they must be considered in studies about the risk potential of resistance evolution. The current study sets the differences in the feeding behavior of neonate Alabama argillacea (Hübner) (Lepidoptera: Noctuidae) larvae expos
