RODRIGUEZ, J et al. Identificación de progenitores de tomate (Solanum lycopersicum) para la obtención de híbridos F1 adaptados a las condiciones de Cuba. cultrop [online]. 2008, vol.29, n.3, pp. 69-72. ISSN 0258-5936.
The present study was carried out at the National Institute of Agricultural Sciences (INCA), with the objective of evaluating 14 tomato cultivars coming from different regions and breeding programs to identify, through qualitative and quantitative analyses, those progenitors enabling to obtain national high-quality hybrids. The experiment was performed in asbestos cement gutters with a microjet irrigation system under organoponic conditions. Results from the Main Components analyses showed those quantitative characters contributing the most to the total variation, standing out fruit number per plant, average fruit weight and polar as well as equatorial diameters in component 1, whereas in component 2 stood out yield per plant and days to flowering and maturity of studied cultivars; meanwhile Biplot and Cluster Analysis Dendrogram representation allowed to identify cultivars LMN-64, Vyta, Amalia, Floradel AN-104-1 and A4 with the highest differences among themselves in the evaluated characters.
