It provides a method for the selection of an alfalfa plant with improved nutritional value and greater flexibility, whether to increase Forage Quality provided, either to improve the biomass available previously. Plant. Alfalfa Seed and Product Processing.Claim 1: a method for the selection of an alfalfa Plant Components with enhanced nutritional value, from a population of Alfalfa plants, where the population of Alfalfa plants comprising a recombinant DNA Molecule, and where a portion of the Molecule. Recombinant DNA is homologous or complementary to sec. Id. no. 1 sec. Id.No. 2, comprising: (a) the Measurement of the concentration of acid detergent lignin (ADL) in a Lower STEM tissue of each of these alfalfa plants in this population of Alfalfa plants.Where the concentration of ADL is reduced from approximately 31% and 12% in comparison with a Lower STEM tissue of an alfalfa plant that does not understand the DNA Molecule； (b) the Measurement of the concentration of guaiacil (G lignin lignin) in the lower STEM tissue, where And the content of G lignin is reduced about 25% or more in the lower STEM tissue.Compared with tissue of Lower stem of Alfalfa Plant which includes the DNA Molecule； (c) measuring the component of neutral Detergent Fiber digestibility (ndfd) in the lower STEM tissue.Where the value of ndfd is increased by more than 18% in the lower STEM Tissue compared with tissue of Lower stem of Alfalfa Plant which includes the DNA Molecule； (d) the selection of an alfalfa plant that includes components of nutritional value. Prayed the steps (a) - (c)； and (e) the cultivation of the alfalfa Plant selected in STEP (d).Se provee un método para la selección de una planta de alfalfa con mejorado valor de alimentación y mayor flexibilidad, ya sea para incrementar la calidad de forraje proporcionada, ya sea para mejorar la biomasa disponible con anterioridad. Planta. Semilla y producto de alfalfa procesado. Reivindicación 1: Un método para la selección de una plan
