Naomi Poinsettia (Euphorbia pulcherrima Willd. ex Klotzsch) variety for indoor spaces

Abstract

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 experimentaldesign 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 itsnerves.Study Limitations/Implications: The variety is propagated asexually via cuttings andthe plants from which the cuts are made are preserved as mother plants. It needsadequate 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.

“…Las brácteas son de forma elíptica y de color rojo. Es una variedad de ciclo tardío de acuerdo a la respuesta del fotoperiodo (Canul-Ku et al, 2022a).…”

“…Las nuevas variedades mejoradas que se introducen al país carecen de evaluaciones previas en vivero de productores, lo cual conduce a un crecimiento y desarrollo anormal, pigmentación de brácteas fuera del periodo comercial, por lo que las plantas no tienen la calidad comercial y se traduce en pérdidas económicas. El precio del material vegetativo para el establecimiento del cultivo incluye el pago de regalías, lo cual causa aumento en los costos de producción (Canul-Ku et al, 2017a). Así, el productor cultiva lo que las empresas ofertan de material vegetativo, sin tener en cuenta los gustos y las preferencias del consumidor, menos las condiciones ambientales de los centros de producción.…”
