ALONSO, Maruchi et al. Evaluación de tres cultivares de papaya del grupo Solo basada en caracteres de crecimiento y productividad. cultrop [online]. 2008, vol.29, n.2, pp. 59-64. ISSN 0258-5936.

Papaya (Carica papaya L.) is one of the most important and widely spread fruit trees in tropical and subtropical countries. Due to the monovarietal explotation of ‘Maradol’ cultivar in Cuba, this crop is submitted to serious risks. Thus, the introduction, characterization and maintenance of new cultivars in the germplasm of this species constitute a key factor to identify and obtain new genotypes. This work presents the behaviour of three papaya cultivars introduced in the fruit germplasm bank from the Research Institute of Tropical Fruit Crops. Results indicate that cultivars ‘BH-65’ and ‘Baixinho de Santa Amalia’ showed significant plant height differences compared to ‘Sunset’. More than 100 leaves were emitted per year, which indicates a good genotypic adaptability to the contidions of this trial. Cultivars ‘BH-65’ and ‘Baixinho de Santa Amalia’ emitted the first flower at a lower plant height, a useful feature for productive purposes. In general, all papaya cultivars from Solo group had a favourable growth and vegetative development as well as an excellent productivity. It is a great advance to conduct further breeding programs to be used for commercial purposes. The mere introduction of new cultivars from ‘Solo group’ to the country could promote a crop production increment and therefore open future fruit market ways for exportation due to its trade success
