A., “Selection between and within full-sib sugarcane families using the modified BLUPIS method (BLUPISM)”, vol. 15, p. -, 2016.

The objective of this study was to assess the efficiency of a modification of the simulated individual best linear unbiased prediction (BLUPIS) procedure, which is used for the approximation of classic individuals (BLUPI) for selection between and within sugarcane families. A total of 110 full-sib families were employed in an experiment initiated in 2007 using a randomized block design with five replicates. The variable tons of stalks per hectare was measured from a plot containing 20 plants.

Paternity identification in sugarcane polycrosses by using microsatellite markers

M. A. Xavier, Pinto, L. R., Fávero, T. M., Perecin, D., Carlini-Garcia, L. A., and Landell, M. G. A., “Paternity identification in sugarcane polycrosses by using microsatellite markers”, vol. 13, pp. 2268-2277, 2014.

Although polycrosses have been used to test the potential of cross-combination of a large number of sugarcane parents, the male parent of the half-sib progenies produced is unknown. The present study aimed to integrate the molecular marker technology to the sugarcane polycross approach by the application of microsatellite markers to identify the male parent of 41 elite clones derived from polycross families.

Relationships between methods of variety adaptability and stability in sugarcane

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 investigate the relationship between methods of adaptability and stability in sugarcane. Data were collected from trials using a randomized block design with three repetitions and 15 clones of sugarcane in nine environments in the State of Minas Gerais, Brazil.
