Abstract
- The aim of this study was to evaluate the efficiency of selection of potato families in early generations for heat tolerance. Thirty families were evaluated in the seedling generation (SG), first clonal generation (FCG) in the field and greenhouse under high temperature conditions, and second clonal generation (SCG) under mild temperatures. The mean of the families was obtained in each generation. The 16 most productive families in FCG were selected, and the clones of these families were evaluated in experiments in the winter and rainy crop seasons. The results showed that family selection for tuber shape may be applied as of the SG. It was also observed that family selection in the FCG and SCG for yield and tuber specific gravity contributed to identification of clones tolerant to heat and responsive to environmental improvement. Resumo O objetivo deste trabalho foi avaliar a eficiência da seleção de famílias de batata nas gerações precoces para tolerância ao calor. Foram avaliadas 30 famílias na geração seedling (SG), primeira geração clonal (FCG) em campo e casa de vegetação sob condições de temperaturas elevadas e segunda geração clonal (SCG) sob temperaturas amenas e obtidas as médias das famílias em cada geração. Foram selecionadas 16 famílias mais produtivas na FCG e os clones dessas famílias foram avaliados em experimentos nas safras de inverno e "das águas". Os resultados mostraram que a seleção de famílias para formato de tubérculos pode ser aplicada desde a SG. Também observou-se que a seleção de famílias na FCG e SCG para produtividade e peso específico de tubérculos contribuiu para a identificação de clones tolerantes ao calor e responsivos a melhoria ambiental.
