Abstract

Poinsettia (Euphorbia pulcherrima Willd. ex Klotzsch) is native to Mexico and Mesoamerica. Its cultivation depends on improved varieties from abroad, which causes foreign exchange losses and economic losses. Currently its import is restricted. This represents an opportunity to offer varieties generated in the country. The INIFAP, Experimental Field Zacatepec realizes the genetic improvement of poinsettia. Thus, in 2010 by manual cross between MOR13 x MORPR10 F1 progeny was obtained, which was evaluated in 2011 and in the immediate cycle the number of plants increased. In 2013, clonal hybrid progeny (barb) with a commercial variety (pattern) were grafted by wedge; in 2014, graft cuttings were obtained, they were grown to a finished plant and selected according to the biotype demanded by the market. In 2015 it was evaluated in a nursery in Tetela del Monte, Cuernavaca, Morelos. In 2016, the varietal description was made with Leticia name. This variety has an intermediate size of great amplitude with intermediate branching, leaves of large oval shape with petioles of medium length, bracts of elliptical shape and red. It is of intermediate response, the pigmentation of bracts appears nine weeks after the beginning of autumn.
