Caracterización morfológica y fenológica de la diversidad de tomates silvestres (Sección Lycopersicon) distribuidos en Ecuador.

Abstract

Abstract:The present work was developed with the objective of analyzing the morphological and phenological diversity of five species of wild tomatoes belonging to the Lycopersicon section, represented by 34 accessions of the seed banks of the UTPL and the INIAP. Twenty-two quantitative morphological characters and 14 sub phenological scales were evaluated. The data were subjected to multivariate analyzes (groupings and main components). The evaluated materials showed a wide variability for the morphological characters, the most representative ones related to the number of inflorescences, flowers, infrutescences and fruits, including the weight of the fruit; so that the accessions of S. habrochaites of the other species have been clearly differentiated, finding a differentiation in turn between S. pimpinellifolium, S. neorickii, S. galapagense and S. cheesmaniae. With respect to the phenological characterization, the most representative sub scales have been the development of inflorescences and infrutescences, resulting that the accessions of S. neorickii and S. pimpinellifolium have been the earliest materials; a tendency to differentiation between species is also generated here. With the results found there is a morphological and phenological profile of the 34 accessions and of each species studied, information relevant to its conservation and use both for plant improvement and for consumption and possible commercialization of fruits of certain species.
