Summary:ABSTRACT The aim of this work was to evaluate the performance of advanced potato clones for plant vigor, tuber yield components and specific gravity. Two sets of advanced clones and two control cultivars broadly grown in Brazil were compared. The first set, formed by 11 clones, was evaluated in the spring season of 2010, and the second, constituted by six clones, in the autumn season of 2011, in Canoinhas, Santa Catarina State, Brazil. The design of both experiments was a randomized complete block with four replications of two rows of 10 plants each. Plant vigor, tuber yield components and specific gravity were evaluated. The data of each experiment were submitted to analysis of variance and grouping means. Plant vigor was highly influenced by the environment. In the first set, 2197-15 and CL02-05 were the best clones for tuber yield traits. ‘2197-15’ presented potential for processing and fresh market, with high plant vigor, whereas ‘CL02-05’ showed potential only for fresh market, and less vigorous plants. In the second set, again the outstanding clone was CL02-05. RESUMO O objetivo do trabalho foi verificar o desempenho de clones avançados de batata em relação a vigor de planta, caracteres componentes de rendimento de tubérculos e peso específico. Foram comparados dois conjuntos de clones avançados e duas cultivares plantadas amplamente no Brasil. O primeiro conjunto, formado de 11 clones, foi avaliado na safra de primavera de 2010, e o segundo constituído de seis clones, na safra de outono de 2011, em Canoinhas-SC. O delineamento de ambos os experimentos foi blocos casualizados com quatro repetições de parcelas de duas linhas de 10 plantas cada. Foram avaliados o vigor vegetativo de planta, os componentes do rendimento de tubérculos e o peso específico. Os dados de cada experimento foram submetidos à análise de variância e de agrupamento de médias. O caráter vigor das plantas foi muito influenciado pelo ambiente. No primeiro conjunto de clones, 2197-15 e CL02-05 foram os melhores para os caracteres de rendimento de tubérculos, sendo que ‘2197-15’ apresentou potencial para processamento industrial além do mercado fresco, e plantas com maior vigor, enquanto ‘CL02-05’ limitou o potencial apenas ao mercado fresco com plantas de menor vigor. No segundo conjunto, novamente o destaque coube ao clone CL02-05.
