In searching for alternative forage legumes, there is a need for increased emphasis on understanding the influence of environment on quality and anti-quality factors. The tropical pasture legume Desmodium ovalifolium contains high levels of tannins, which, however, vary among accessions and seem to be influenced by environmental factors. A core collection of 18 accessions was selected based on geographic origin, and agronomic and quality parameters. A multilocational trial with this core collection was initiated in six contrasting environments in Colombia to identify soil fertility and climate effects on tannin contents.
