Objective: To evaluate the behavior of the Naomi poinsettia variety and its varietal description applying the guidelines of the Union for the Protection of New Varieties of Plants (UPOV).
Design/Methodology/Approach: The variety was generated through the following methods: plant genetic hybridization, individual selection, and use of the grafting technique. The varietal description was based on the document of the Union for the Protection of New Varieties of Plants (UPOV). A completely randomized experimental
design with 10 replications was used. Vegetative and reproductive characteristics of the plant were recorded. The data was subjected to an analysis of variance and Tukey’s mean comparison test (P ≤ 0.05).
Results: The Naomi variety is tall with intermediate width and branching. It has a very intense green color in the middle third of the stem. It has oval-shaped leaves of intermediate size, with a rounded base, and without curvature in the main nerve. Its elliptical bract does not have a torsion, but it has an intermediate roughness between its
Study Limitations/Implications: The variety is propagated asexually via cuttings and
the plants from which the cuts are made are preserved as mother plants. It needs
adequate nutrition and light and temperature conditions that hinder floral differentiation.
Findings/Conclusions: The new poinsettia material has phenotypic attributes demanded by the market. The varietal description indicates that it is comparable with other INIFAP varieties and with commercially available varieties. This plant can be considered a competitive candidate for the diversification of the offer of poinsettia plants in the Christmas season.
