Results of a Gliricidia sepium (Walp) Steud. provenance and family trial in tropical humid forest conditions
Agroforestry has been identified as an alternative for sustainable land use in the tropics. Gliricidia sepium (Jacq.) Steud, a legume tree specie native from Mexico to Panama throughout Central America has shown potential in agroforestry for its multiple uses. The present study started with the following objectives: to determine the amount of variation among provenances and families within provenanaces, and to select superior genotypes for the different agroforestry systems. An evaluation of growth parameters and biomass quantity and quality was made on trees from a total of 177 families of 12 provenances. Multivariate statistical procedures were used to study the variation of this plant material. High variation was observed for all the variables among provenances and families within provenances. A clear separation of provenances was observed from the multivariate results, only a 9,7 of misclassification was obtained from the Discriminant Analysis.
