Sin embargo, su domesticación, diversidad genética e historia han sido poco estudiadas. En este trabajo se analizó la diversidad genética y las relaciones de parentesco de nochebuenas de parques y jardines del Distrito Federal, México, a fin de evaluar la diversidad genética e identificar la procedencia de las nochebuenas sembradas en esta zona urbana. Las plantas del Distrito Federal representan 2 variantes genéticas o haplotipos. Una de estas variantes proviene del estado de Guerrero, mientras que la otra pertenece a cultivares mexicanos cercanamente emparentados a las poblaciones silvestres de Guerrero y Morelos. Documentos históricos señalan que desde la época prehispánica las nochebuenas se cultivaban en el centro de México, y en un manuscrito de 1801 se ilustran nochebuenas en los jardines de la Nueva España con modificaciones con respecto a las silvestres. El reconocimiento de la diversidad genética de plantas cultivadas, así como la inferencia de su posible origen geográfico, permitirá la protección, manejo sostenible, conservación y mejoramiento genético del germoplasma mexicano de nochebuena.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Poinsettia (Euphorbia pulcherrima ) is one of the most economically and culturally important ornamental plants in the world because it is the floral symbol of Christmas. However, little is known about its domestication, genetic diversity and history. This paper analyses the genetic diversity of plants grown in gardens and parks of the Distrito Federal, Mexico, and we compare it with that found in wild populations to document the genetic diversity of poinsettia represented in the Distrito Federal and its relationship to the plant's origin. The plants found in the Distrito Federal are 2 genetic variants or haplotypes. One of these variants belongs to the state of Guerrero and the other belongs to a variant closely related to wild populations of Guerrero and Morelos. Historical documents show that since the Pre-Hispanic era, poinsettias were grown in central Mexico and in a manuscript from 1801 poinsettias are illustrated in the gardens of New Spain with modifications as compared to wild plants. The recognition of the genetic diversity of cultivated plants will allow the protection, sustainable management, conservation and genetic improvement of Mexican poinsettia germplasm.]]></p></abstract>
