“…This result shows that a large portion of the variance was associated to the additive action of the genes. To assess the genetic patterns of sugar cane, Barbosa et al (2005), aimed to predict the additive of genes value for the selection of the parents and the families based on REML/ BLUP analysis in 113 full sib families. The authors showed that the additive genetic effects were predominant for certain characteristics, including the number of culms, average weight of a culm, and ton of sugar cane per hectare (TCH).…”

ABSTRACT. This study evaluated different strategies to select sugar cane families and obtain clones adapted to the conditions of the Brazilian savannah. Specifically, 7 experiments were conducted, with 10 full sib families, and 2 witnesses in common to all experiments, in each experiment. The plants were grown in random blocks, with witnesses in common (incomplete blocks), and 6 repetitions of each experiment. The data were analyzed through the methodology of mixed patterns, in which the matrices of kinship between the families were identified by the method of restricted maximum likelihood. The characteristics that were evaluated included soluble solids content (BRIX), BRIX ton/ha, average mass of a culm, number of culms/m, and tons of culms/ha. A multi-diverse alternative based on the analysis of groupings by using the UPGMA method was used to identify the most viable families for selection, when considering the genotypic effects on all characteristics. This method appeared suitable for the selection of families, with 5 family groups being formed. The families that formed Group 2 appeared superior to all other families for all the evaluated characteristics. It is recommended that the families in Group 2 are preferentially used in sugar cane improvement programs to obtain varieties optimally adapted to the conditions of the Brazilian savannah.

“…The smaller is the coeffi cient of variation of a trait, the greater is the experimental accuracy. The high coeffi cients of variation can be interpreted with low experimental precision, which affects the inferences that can be made for the observed traits (BARBOSA et al, 2005).…”

“…Thus, the selection of the best families in sugarcane may be performed as based on the number of stalks (NS), whose heritability based on mean values of families has been greater than the heritability with individual plants, as shown by Kimberg and Cox (2003), Barbosa et al (2005) and Oliveira et al (2008). In addition, its direct effect on SW is of great magnitude.…”

-The aim of this research was to evaluate the consistency of path analyses in sugarcane experiments based on genetic, phenotypic and genotypic correlations. Forty-four analyses were made with a view toward quantifying the direct and indirect effects of stalk height (SH), stalk diameter (SD) and number of stalks (NS) on sugarcane weight (SW). NS had the greatest direct effect on SW in all the analyses with the use of genetic and phenotypic correlations and in 12 analyses with use of the genotypic correlations. SD had a high direct effect on SW, going beyond NS in only one experiment, while SH had the lowest direct effect on SW in most of the experiments. The results showed greater consistency with the use of genetic and phenotypic correlations. In the balanced experiments, the phenotypic and genetic correlations showed equivalent results. NS is the main determinant of changes in sugarcane production.
