Abstract

TORAL, Odalys C.; NAVARRO, Marlen  and  REINO, J. Prospection and collection of species of interest for livestock production in two Cuban provinces. Pastos y Forrajes [online]. 2015, vol.38, n.3, pp. 157-163. ISSN 2078-8452.

A mission of prospection was carried out in Las Tunas and Camagüey provinces, in order to collect samples of herbaceous, shrub and tree species of multipurpose use in the livestock production sector, to create a germplasm bank. When abundant population was found a random sampling method was used, and in small populations individual sampling was made, in which species were repeated in different sites. The information was gathered through several descriptors related to the location, natural habitat, vegetation, soil and damage caused by insects and microorganisms. In the prospected zones a high genus and species diversity was concentrated, for the accessions of herbaceous type (17 genera with 23 species) as well as for the tree and shrub accessions (13 genera with 15 species). A total of 55 accessions of 38 herbaceous and 17 shrub and/or tree species were collected. The highest diversity of species was found on the soils of the Brown and Fersialitic groupings, which are more fertile and show better permeability. Species that have been used with diverse purposes were collected, belonging to the genera: Teramnus, Lablab, Cynodon, Clitoria, Canavalia, Centrosema and Leucaena; as well as new materials (Sesbania sp. and Cassia sp.) which could be used as living fence, cover plants and green manure. It is considered that the collection provides a material with excellent multiuse perspectives in the livestock production sector, and contributes to the increase of the existing germplasm reserve with naturalized ecotypes.
