| dc.description.abstract | Description of the subject: Principal Component Analysis (PCA) and Morphological Similarity Coefficient were used for the objective to determine the ability of the 29 morphological descriptors in distinguishing lettuce cultivars. Objective: The characterization of five lettuce cultivars was performed based on a study of 29 morphological descriptors proposed by the International Union for the Protection of New Varieties of Plant (UPOV). Methods: Twenty-three descriptors quantitative, and six pseudo qualitative were analyzed in the present study. Results. PCA showed that 13 descriptors out of 29 were admitted as the most important descriptors. Morphological similarity coefficient suggested that the five lettuce cultivars belonged to three clusters. Conclusion: The results of the current study indicated that the use of morphological descriptors, along with morphological similarity analysis and PCA, proved to be effective for discriminating lettuce cultivars. | en_US |
