“…Each block had 2 grooves, containing 10 plants each. Each family was represented by 120 genotypes (20 genotypes per block), of which the seedlings were obtained from seeds previously produced in the Sugarcane Flowering and Crossing Station of Serra do Ouro of Rede Interuniversitária para o Desenvolvimento do Setor Sugroenergético -RIDESA (Barbosa et al, 2002). Witnesses used in this experiment were 2 sugar cane varieties, RB867515 and RB855156.…”

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 families used in this study were sampled from crosses carried out at the Experimental Station of Serra do Ouro (BARBOSA et al, 2002), in the municipality of Murici, in the state of Alagoas. Samples were removed from 68 biparental crosses (full-sib) of this experiment.…”

“…These progenies were obtained using standard procedures at the RIDESA sugarcane breeding program (Barbosa et al 2002), where plants were cultivated in the field before opening of the anthers, and subsequently protected to avoid contamination from foreign pollen. Plants were cultivated in Hawaiian nutrient solution (Heinz and Tew 1987) for the duration of the experiment.…”
