Authors: J.A. Dutra Filho, T.C. Junior, D. E. Simoes Neto, L. S. Souto, Romulo Gil de Luna A.S. Souza
Sixty-eight sugarcane genotypes were evaluated to determine the number of harvests required to select new genotypes in the sugarcane belt in the state of Pernambuco, northeast Brazil. Using a random block design, the following parameters were evaluated: (i) polarizable sugars (POL) per hectare, in metric tons (TPH); (ii) culm .. Read More»

Implications of the clone by harvest interaction in the selection of sugarcane genotypes in a regionalized program
Authors: D.N.A. Cabral, J.A.R. Nunes, P.D.S. Cabral, J. Zuchi, A.J. Raizer and T.O.M. De Paula
The recommendation of sugarcane clones depends on several factors, as the response or performance of the clones over different cuts or harvests. The clone by harvest interaction might be difficult to identify superior clones in the final stages of the sugarcane breeding program. Thus, the objective of this study was to investi.. Read More»

Sugarcane production is strongly influenced by drought, which is a limiting factor for agricultural productivity in the world. In this study, the gene expression profiles obtained by de novo assembly of the leaf transcriptome of two sugarcane cultivars that differ in their physiological response to water deficit were evaluated..

Relationships between methods of variety adaptability and stability in sugarcane
Authors: T.O. Mendes de Paula, C.D. Marinho, V. Souza, M.H.P. Barbosa, L.A. Peternelli, C.A. Kimbeng and M.M. Zhou
The identification and recommendation of superior genotypes is crucial for the growth of industrial crops, and sugarcane breeding performs a vital role by developing more productive cultivars. The study of genotype x environment interaction has been an essential tool in this process. Thereby, the purpose of this study was to i.. Read More»

Genetic divergence of sugarcane varieties collected in the region of Lavras, Minas Gerais, Brazil
Authors: L.E.V. Cesar, A.T. Bruzi, J.A.R. Nunes, L.A. de B. Andrade, M.F. Lopes,L.R. Sales and M.M. Mour�£o
Genetic diversity among local accessions and varieties subsidize plant breeding programs, allowing the utilization of existing variability in plants that have already adapted to local climate conditions. An alternative to studying genetic variability is the study of diversity. The aim of this research was to study genetic diversity among sugarcane accessi.. Read More»

Genetic analyses, phenotypic adaptability and stability in sugarcane genotypes for commercial cultivation in Pernambuco
Authors: J.A. Dutra Filho; T.C. Junior and D.E. Sim�µes Neto
In the present study, we assessed the agro-industrial performance of 22 sugarcane genotypes adaptable to edaphoclimatic conditions in production microregions in the State of Pernambuco, Brazil, and we recommended the commercial cultivation of select genotypes. The variables analyzed were as follows: sucrose percentage in cane .. Read More»

Comparison between different selection indices in energy cane breeding
Authors: A.A.C. de Azeredo, L.L. Bhering, B.P. Brasileiro, C.D. Cruz,L.C.I. Silveira, R.A. Oliveira, J.C. Bespalhok Filho, E. Daros
Sugarcane breeding programs have been adapting to a new market demand: aside from high sucrose yield per hectare, the sector needs new cultivars with higher fiber percentages. The selection of sugarcane clones based on phenotype alone is a complex task. The selected clones should display high performance in a series of yield- .. Read More»

Authors: B.P. Brasileiro, C.D. Marinho, P.M.A. Costa, E.F.A. Moreira, L.A. Peternelli and M.H.P. Barbosa
We evaluated the genetic diversity of 77 clones of sugarcane used in crosses made by the Brazilian interuniversity network for the development of the sugar/energy sector (RIDESA) breeding program. Characterization of the genotypes was carried out at the ratoon stage, based on eight morphological traits and seven agronomic trai.. Read More»
