Ximena, variety of poinsettia (Euphorbia pulcherrima Willd. ex Klotzsch) to decorate indoor spaces

Abstract

Objective: To describe the variety of Ximena poinsettia based on UPOV guidelines and to evaluate its behavior with a cooperating producer in Morelos state.
Design/methodology/approach: The variety was generated by the genotechnical methods of hybridization, recurrent selection and use of the grafting method. The varietal description was made based on the document of the Union for the Protection of New Varieties of Plants (UPOV). The experimental design used was a completely randomized, with 10 repetitions. Vegetative and bract characters of the plant were recorded. The information was studied by analysis of variance and Tukey means comparison test (P? 0.05).
Results: Ximena is tall, large, with intermediate branching. The leaf is oval, long and wide with a medium length petiole. Elliptical bracts, red color, without torsion and roughness between the nerves. The width of the top is medium, yellow ciatio glands, and without any deformation. Ximena's response was statistically similar to the two controls in stem diameter, number of internodes, leaf width, leaf petiole length and bract. Instead, it was statistically superior in bract length, bract canopy width, and diameter of ciatio.
Limitations on study/implications: The variety is maintained as an original plant, from which commercial crops will be established. Therefore, it requires adequate nutrition and conditions that do not allow its floral differentiation.
Findings/conclusions: Ximena's behavior and archetype was comparable to that of commercial varieties, it has aesthetic characteristics that the market demands, it can be competitive and it is considered a candidate to diversify the offer of poinsettias plants in the Christmas season.
