Characterization in Clonal Selections of Citrus X latifolia Tanaka ex Q. Jiménez: Español

Abstract Objective: To physically and chemically characterize clonal selections with Persian lemon potential. Design/methodology/approximation: A core component analysis was used, using a mixed data factor analysis model. The distribution of genotypes was plotted by major components through the K-medoid method, while cluster analysis it was determined by a Gower dissimilarity matrix. A dendogram was performed by Ward's method with a minimum variance grouping criteria. In the morphological characterization of the fruits which were considered trees of Citrus volkameriana, Citrus macrophylla, Citrus paradisi X Poncirus trifoliata, X Citroncirus spp., Citrus X aurantium. The diameter, length, weight, color and shape of the fruit was analyzed. Other variables to evaluate were the shape of the base, apex shape, surface texture, albedo adhesion, number of seeds, maturation rate, juice weight, juice yield, pH, Brix and tidable acidity. Data analysis was performed with R software and the factoextra and FactoMineR packages. Results: The physical and chemical characteristics of Persian lemon fruits varies due to the correlation between the different types of rootstock grown in the citrus area studied. Study limitations/implications: Producers are unaware of the clone or type of plant material they propagate, making selections of clones that show outstanding morphoagronomic characteristics. Findings/conclusions: The morphological diversity and quality fruit is closely related to the type of rootstock used for its spread. The internal and external characteristics in Citrus macrophylla stand out as the fruit.Objective: To physically and chemically characterize clonal selections of Persian lime(Citrus x latifolia Tanaka ex Q. Jiménez).Design/Methodology/Approach: The principal components analysis was employed,using a mixed data factorial analysis model. Genotype distribution was graphed usingprincipal components with the k-medoids method, while a Gower’s dissimilarity matrixwas determined for the conglomerate analysis and a dendrogram was developed usingWard’s minimum variance cluster method. For the morphological characterization of thefruits, the study considered the following trees: Citrus volkameriana, Citrus macrophylla,Citrus paradisi X Poncirus trifoliata, X Citroncirus spp., and Citrus X aurantium. Thefruit’s diameter, length, weight, color, and shape were analyzed, in addition to its baseshape, tip shape, surface texture, albedo adherence, number of seeds, ripening rate,juice weight, juice yield, pH, °Brix, and titratable acidity. Data were analyzed using Rsoftware and the factoextra and FactoMineR packages.Results: The physical and chemical traits of Persian lime fruit vary due to thecorrelations between the types of rootstock that are cultivated in the citrus zone studied. Study Limitations/Implications: Farmers do not know which clone or type of plantmaterial they propagate; they simply select clones that show outstanding morpho-agronomical traits.Findings/Conclusions: The morphological diversity and quality of the fruit is related tothe type of rootstock used in its propagation, in addition to internal and external traits inCitrus macrophylla standing out in fruit quality
