Morphoagronomic and isoenzymatic characterization of 23 accessions of Leucaena spp
Antecedents and objectives Leucaena leucocephala (Lam.) de Witt, is the species that has been most used throughout the world and has been widely studied in animal feeding.In Cuba, the main studies of characterization and identification of this species have focused mainly on morphoagronomic characteristics under field conditions, or in isolated trials, including only the four varieties recorded as commercial ( cv.Ipil‐Ipil ;cv.Perú ;cv.Cunningham and cv.CNIA‐250 ).The electrophoresis of isoenzymes favored the use of more efficient genetic markers than the morphological markers in many occasions.In spite of being influenced by the environmental action and depending on the tissue and developmental stage of the plant that is evaluated, these relatively simple, cheap and co‐dominant markers, allow us to distinguish the homozygous and heterozygous genotypes, and thus develop studies of mapping and binding,population genetics,etc.(Bretting and Widrlechner,1995).The objective of this work was the morphoagronomic and isoenzymatic (esterases, peroxidases and alcohol dehydrogenases) characterization of a sample of 23 accessions that included five species of the Leucaena genus (L.leucocephala, L.lanceolada, L.diversifolia, L.macrophylla y L.esculenta).
