| Abstract: The objective of this work was to estimate the genetic parameters for the performance prediction of sugarcane (Saccharum spp.) families under natural cold stress, in Southern Brazil, and to identify the best combinations of parents aiming at the selection for tolerance to cold. Fifty-three full-sib families were evaluated in an incomplete block design, with five replicates per family, in the municipality of Pelotas, in the state of Rio Grande do Sul, Brazil. Harvest occurred in August 2013, nine months after planting and after cold spells with negative temperatures down to -2.2ºC. Statistical analyses, performed with the mixed model methodology, detected significant differences among families. Heritability estimates among progeny means were... |

| O objetivo deste trabalho foi avaliar a adaptabilidade e estabilidade de genótipos de cana‑de‑açúcar de maturação precoce, quanto à produtividade de colmos e de Brix, no Estado do Rio Grande do Sul. Quinze genótipos de maturação precoce foram avaliados nas safras 2009/2010 e 2010/2011, por meio da análise de efeitos principais aditivos e interações multiplicativas (AMMI). As interações genótipo x ambiente foram de alta significância e evidenciaram a alteração de posição na classificação dos genótipos de um ambiente para outro. Novos genótipos superaram, em produtividade e estabilidade, o genótipo‑padrão precoce RB855156, embora este ainda se destaque pela produtividade, estabilidade moderada e ampla adaptabilidade. O genótipo RB966928 destacou-se pela... |

| ABSTRACT: The purpose of this study was to select cold-tolerant sugarcane families and clones. Evaluations were carried out during three selection phases in the municipality of Pelotas, state of Rio Grande do Sul, Brazil. The experiments were arranged in an incomplete block design, with initially 4,452 seedlings of 53 full-sib families. Aside from the traits soluble solids content (BRX), tons of stalks per hectare (TSH) and tons of brixper hectare (TBH), the survival of the apical bud (ABS) was evaluated in the first selection stage (T1) of the breeding program. At the end of three selection phases, 15 clones of 14 of the 53 families evaluated in the first phase (T1) were selected for the experimental phase. Of these, the clones RS/PR126066, RS/PR126044,... |
