1. Transcription factors and molecular markers revealed asymmetric contributions between allotetraploid Upland cotton and its two diploid ancestors
ABSTRACT Three Gossypium species have been used to breed cotton as they vary in their fiber production and resistance to stresses. Transcription factors (TFs) mostly are present in different copies or isoforms by which they conduct their regulation. Their copy number can determine organism behavior to a cue. Simple sequence repeats (SSRs) are one of the most

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. Selection of upland cotton for the Brazilian semi-arid region under supplementary irrigation
Abstract This study aimed to select cotton genotypes adapted to semi-arid conditions grown with supplementary irrigation. Two experiments were carried out between March and July 2016 in Serra Talhada- Pernambuco and Apodi-Rio Grande do Norte, Brazil. Eighteen elite genotypes bred by Embrapa Cotton and two controls (BRS 286 and BRS 336) were evaluated under d

5. Diallel analysis and inbreeding depression in agronomic and technological traits of cotton genotypes
ABSTRACT Cotton provides about 90% of the world textile fiber, and is one of the crops of greater industrial relevance. The objectives of this study were to estimate the inbreeding depressionand the genetic effects involved in the control of the agronomic andfiber quality traits in F1 and F2 generations and to identify promising hybrids for obtaining superio

6. Sequence-related amplified polymorphisms (SRAPs) reveal genetic diversity and variation regions in upland cotton (Gossypium hirsutum L.) in China
Abstract The lack of genetic diversity is an obstacle for genetic improvement of upland cotton in China; thus, new technologies must be developed to produce more polymorphic molecular markers associated with agricultural traits of the existing resources for breeding. A highly efficient and economical technology of sequence-related amplified polymorphism (SRA

7. BRS 368RF: A glyphosate tolerant, midseason upland cotton cultivar for Northeast and North Brazilian cerrado
Abstract Cotton cultivar BRS 368RF was developed by EMBRAPA in a partnership with the Bahia Foundation, aiming to create high-yielding germplasm by adding transgenic traits addressed to Brazilian Savanna (cerrado) of the Northeast and North regions. BRS 368RF is a midseason cultivar and has yield stability and transgenic tolerance to glyphosate.

8. BRS 369RF and BRS 370RF: Glyphosate tolerant, high-yielding upland cotton cultivars for central Brazilian savanna
Abstract BRS 369RF and BRS 370RF were developed by the EMBRAPA as a part of efforts to create high-yielding germplasm with combinations of transgenic traits. BRS 369RF and BRS 370RF are midseason cultivars and have yield stability, adaptation to the central Brazilian savanna, good fiber quality and tolerance to glyphosate herbicide.

12. Selecao recorrente para resistencia a ramulose do algodoeiro (Gossypium hirsutum L. var. latifolium Hutch).
Este trabalho teve como objetivo desenvolver linhagens de algodoeiro resistentes a ramulose. Foram utilizados tres ciclos de selecao recorrente, no final dos quais foram comparados os niveis de resistencia a doenca das populacoes melhoradas com o da populacao original nao-melhorada, da qual foram obtidas. Evidenciou-se que a partir do segundo ciclo de seleca
