Resumen

RODRIGUEZ, C. J et al. Evaluación de la heterosis y heredabilidad en híbridos cubanos de tomate (Solanum lycopersicum). cultrop [online]. 2008, vol.29, n.3, pp. 63-68. ISSN 0258-5936.

The characters of yield and its components were evaluated in tomato F1 hybrids, obtained through two statistical genetic designs (Top cross and Biparental) and their progenitors, seeded within the optimal crop season (October 15-December 20, 2006) at the National Institute of Agricultural Sciences. The experiment was performed in asbestos cement gutters with a microjet irrigation system under organoponic conditions. The percentage of heterosis and narrow-sense heritability was estimated. The study of heterosis enabled to identify those hybrids showing a better behavior than their cultivars of origin, regarding many important characters for the producer, reaching the highest yield values at the Top cross, and yield as well as fruit number at the Biparental one. Every character showed high values of heritability, except yield per plant with mean values.
