Authors: MC Reis, DBO Cardoso, EG Silva J�ºnior, BC Gomes, LTG Pereira, DA Gomes and LB Sousa.
The cotton crop has notable importance for Brazilian and worldwide economy. Relationships knowledge among characters allows developing alternatives that increase the genetic progress with simultaneous selection of several traits. The use of correlation estimates for use in indirect selection helps the breeder in the selection .. Read More»

Molecular identification of variety purity in a cotton hybrid with unknown parentage using DNA-SSR markers
Authors: X.Q. Fu, F.X. Yang, X.K. Lu, X.G. Wang, B.X. Yang, F.J. Liu, Y. Liu and J. Peng
Molecular identification of hybrid purity is difficult in regional trials of cotton varieties and hybrid trials. In particular, the molecular detection of hybrid purity has not yet been reported in the case of unknown parentage. In this study, we screened 5000 pairs of primers and chose 17 pairs of core simple sequence repeat .. Read More»

Genetic diversity of arboreal cotton populations of the Brazilian semiarid: a remnant primary gene pool for cotton cultivars
Authors: I.P.P. de Menezes, L.V. Hoffmann, T.H. de Lima, A.R. da Silva, V.S. Lucena and P.A.V. Barroso
Mocó cotton belong to the same species as the cultivated species, Gossypium hirsutum, and cultivated forms were mainly landraces but also developed as cultivars, bearing good fiber quality and drought tolerant when cropped as a perennial species. The northeast Brazil crop system based on this cotton type is finished, wi.. Read More»

Assessment of allelic diversity among drought-resistant cotton genotypes using microsatellite markers
Authors: A. Javaid, F.S. Awan, F.M. Azhar and I.A. Khan
Drought, in conjunction with high temperature, is an important environmental constraint to cotton production. Development of cotton varieties with increased tolerance against adverse environmental conditions has been proposed as effective strategy for ensuring reliable yields. In the present study, 30 simple sequence repeat (S.. Read More»

Novel method to establish molecular identity using inter-simple sequence repeat markers in cotton (Gossypium hirsutum) cultivars
Authors: Z.-Y. Zhao, M.-X. Zhi, Z.-Y. Zhang, H.-L. Sun, Y.-S. Liu and X.-J. Li
Plant molecular identity (ID) is used to describe molecular characteristics of plants, which should contain all of the necessary information. Using inter-simple sequence repeat (ISSR) primers, molecular ID can be described in a way that reflects the polymerase chain reaction (PCR) conditions, annealing temperature, and the ban.. Read More»

Natural hybridization between Gossypium mustelinum and exotic allotetraploid cotton species
Authors: I.P.P. de Menezes1, J.O. da Silva1, G. Malafaia1, R.D.D. Silveira1 andP.A.V. Barroso2
Cotton has been collected in Brazil for decades for its conservation, evaluation, and the use of its genetic resources. Gossypium mustelinum is an allotetraploid cotton species that only occurs in Brazil, and little is known about its genetic potential for improvement. However, the species is threatened by habitat fragmentation and interspecific hybridiza.. Read More»

Identification of RNA editing sites in cotton (Gossypium hirsutum) chloroplasts and editing events that affect secondary and three-dimensional protein structures
Authors: Y. Jiang, S.L. Fan, M.Z. Song, J.N. Yu and S.X. Yu
RNA editing can alter individual nucleotides in primary transcripts, which can cause the amino acids encoded by edited RNA to deviate from the ones predicted from the DNA template. We investigated RNA editing sites of protein-coding genes from the chloroplast genome of cotton. Fifty-four editing sites were identified in 27 tra.. Read More»

Analysis of upland cotton (Gossypium hirsutum) response to Verticillium dahliae inoculation by transcriptome sequencing
Authors: B.X. Shao, Y.L. Zhao, W. Chen, H.M. Wang, Z.J. Guo, H.Y. Gong, X.H. Sang, Y.L. Cui and C.H. Wang
Verticillium wilt is one of the main diseases in cotton (Gossypium hirsutum), severely reduces yield and fiber quality, and is difficult to be controlled effectively. At present, the molecular mechanism that confers resistance to this disease is unclear. Transcriptome sequencing is an important method to detect resistance genes, explore metabolic pathways..

Combining ability analysis for within-boll yield components in upland cotton (Gossypium hirsutum L.)
Authors: M. Imran A. Shakeel F.M. Azhar J. Farooq M.F. Saleem A. Saeed W. Nazeer M. Riaz M. Naeem A. Javaid
Cotton is an important cash crop worldwide, accounting for a large percentage of world agricultural exports; however, yield per acre is still poor in many countries, including Pakistan. Diallel mating system was used to identify parents for improving within-boll yield and fiber quality parameters. Combining ability analysis was employed to obtain suitable pa.. Read More»

Genetic diversity among exotic cotton accessions as for qualitative and quantitative traits
Authors: L.P. de Carvalho, F.J.C. Farias, J.I.S. Rodrigues, N.D. Suassuna and P.E. Teodoro
Studying genetic diversity among a group of genotypes is important in genetic breeding because identifying hybrid combinations of greater heterotic effect also increases the chance of obtaining plants with favorable allele combinations in an intra-population selection program. The objective of this study was to compare differe.. Read More»
