Evaluation of three papaya cultivars from the Solo group based on growth chatacters and productivity
Main Article Content
Abstract
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.
