Resumo: | The objective of this work was to evaluate the combining ability of determinate-growth-habit tomato inbred lines with multiple resistance to Tospovirus and Begomovirus species, ant to identify superior hybrid combinations. The experiment was carried out in greenhouse, with 14 hybrids obtained from crosses of seven lines of the group I (female parents) with two lines of the group II (male parent), in a partial diallel. The following agronomical traits were assessed: total production, early production, mean fruit mass, shape, initial firmness and half life firmness. The parental lines TOM-680 and TOM-682, from group I, stand out with the largest general combining ability (GCA) concerning total production, early production and average fruit mass, while line TOM-585 stood out as to higher values of total production and average fruit mass. In group II, TOM-698 showed higher estimates of GCA as to total production, early production, average fruit mass and initial consistence of the fruits. The hybrid TOM-682xTOM-698 had the highest estimate of general and specific combining ability to total production, early production and average fruit mass, and it is the most promising genotype among the materials tested. |

O experimento foi realizado em casa de vegetação, com 14 híbridos obtidos do cruzamento de sete linhagens femininas (grupo I) com duas linhagens masculinas (grupo II), em um dialelo parcial. As seguintes características agronômicas foram avaliadas: produção total, produção precoce, massa média de frutos, formato, firmeza inicial e firmeza na meia-vida. As linhagens genitoras TOM-680 e TOM-682, do grupo I, se destacaram por exibir as maiores estimativas de capacidade geral de combinação (CGC) quanto às características produção total, produção precoce e massa média de frutos, enquanto a linhagem TOM-585 se destacou quanto aos maiores valores de produção total e massa média de frutos. No grupo II, a linhagem TOM-698 apresentou estimativas superiores de CGC para as características de produção total, produção precoce, massa média dos frutos e firmeza inicial dos frutos. O híbrido TOM-682xTOM-698 apresenta as maiores estimativas de capacidade geral e específica de combinação para produção total, produção precoce e meia-vida da firmeza, e é o genótipo mais promissor entre os materiais testados.
