Abstract – The objective of this work was to estimate the genetic parameters
and to evaluate the genotypic diversity of 12 'Tahiti' acid lime (Citrus latifolia)
genotypes grafted onto two rootstocks. The experiment was carried out from
July 2017 to January 2019, in the municipality of São Mateus, in the state of
Espírito Santo, Brazil. Vegetative (stem diameter, canopy projection diameter,
and plant height), productive (yield and fruit number), and fruit quality (fruit
diameter, soluble solids content, and juice yield) traits were determined. A
mixed model was used to estimate heritability and repeatability coefficients,
as well as to predict clonal values. Scion diversity was determined through
the standardized mean difference of Euclidean distances, and genotypes were
clustered by modified Tocher. Clustering quality and trait importance were
evaluated using the principal component analysis (PCA). Genotypic variance
was observed, which is indicative of the possibility of selection of superior
genotypes. The Tocher method showed the presence of three clusters, which
is in alignment with the PCA results. The multivariate analyses allows of the
selection and the recommendation of superior 'Tahiti' acid lime genotypes.

Resumo – O objetivo deste trabalho foi estimar os parâmetros genéticos e
avaliar a diversidade genética de 12 genótipos de lima ácida 'Tahiti' (Citrus
latifolia) enxertados em dois porta-enxertos. O experimento foi conduzido
de julho de 2017 a janeiro de 2019, no município de São Mateus, no estado
de Espírito Santo, Brasil. Foram mensuradas características vegetativas
(diâmetro de caule, diâmetro de projeção de copa e altura de planta), produtivas
(rendimento e número de frutos) e de qualidade de frutos (diâmetros de fruto,
teor de sólidos solúveis e rendimento de suco). Utilizou-se modelo misto
para estimar os coeficientes de herdabilidade e repetibilidade, bem como
predizer os valores genéticos. A diversidade entre os enxertos foi obtida
por meio da diferença da distância euclidiana média padronizada, e os
genótipos foram agrupados pelo método de Tocher modificado. A qualidade
do agrupamento e a importância dos caracteres foi avaliada pela análise de
componentes principais (ACP). Observou-se variabilidade genética, o que
indica a possibilidade de seleção de genótipos superiores. O método de Tocher
mostrou a presença de três grupos de genótipos, o que foi congruente com
os resultados da ACP. O uso de técnicas multivariadas permite a seleção e a
recomendação de genótipos superiores de lima ácida 'Tahiti'.
