Ornamental horticulture is a dynamic and growing industry that develops new varieties of plants every year. In the case of poinsettia (Euphorbia pulcherrima Willd. ex Klotzsch), the growing demand for new materials in the Mexican market has motivated the Chapingo Autonomous University to generate at least 10 varieties of this species. The genotechnical method for obtaining the variety was the directed cross between the Charllote and Juan Pablo II V-1 varieties in 2018 and the subsequent selection of an individual from the progeny obtained. The progeny were evaluated for two years in Chapingo greenhouses, located in Texcoco, State of Mexico, selecting a segregant, which was named Lupita. This variety is a compact and highly branched indoor plant; the pigmentation of the bracts in Texcoco begins in mid-September and it is fully colored by the end of November, so it requires 10 weeks to pigment. It has intense red bracts in the middle of the inflorescence and a pink-veined red coloration in the other. This variety is a colorful and attractive option for indoor poinsettia producers to grow a variety of Mexican origin with characteristics different from those present in the national market.
