Selection in sugarcane based on inbreeding depression

A. A. C. de Azeredo, Bhering, L. L., Brasileiro, B. P., Cruz, C. D., Barbosa, M. H. P., de Azeredo, A. A. C., Bhering, L. L., Brasileiro, B. P., Cruz, C. D., and Barbosa, M. H. P., Selection in sugarcane based on inbreeding depression, vol. 15, p. -, 2016.

This study aimed to evaluate the gene action associated with yield-related traits, including mean stalk weight (MSW), tons of sugarcane per hectare (TCH), and fiber content (FIB) in sugarcane. Moreover, the viability of individual reciprocal recurrent selection (RRSI-S1) was verified, and the effect of inbreeding depression on progenies was checked. The results were also used to select promising genotypes in S1 progenies.

Genetic analyses, phenotypic adaptability and stability in sugarcane genotypes for commercial cultivation in Pernambuco

J. A. Dutra Filho, Junior, T. C., and Neto, D. E. Simões, Genetic analyses, phenotypic adaptability and stability in sugarcane genotypes for commercial cultivation in Pernambuco, vol. 14, pp. 12102-12110, 2015.

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 juice, tonnage of saccharose per hectare (TPH), sugarcane tonnage per hectare (TCH), fiber, solid soluble contents, total recoverable sugar tonnage (ATR), and total recoverable sugar tonnage per hectare (ATR t/ha).

Genetic divergence of sugarcane varieties collected in the region of Lavras, Minas Gerais, Brazil

L. E. V. Cesar, Bruzi, A. T., Nunes, J. A. R., Andrade, L. Ade B., Lopes, M. F., Sales, L. R., and Mourão, M. M., Genetic divergence of sugarcane varieties collected in the region of Lavras, Minas Gerais, Brazil, vol. 14, pp. 14043-14049, 2015.

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 accessions and varieties used for the production of craft-distilled cachaça (distilled sugarcane alcohol) in the region of Lavras, Minas Gerais, Brazil.
