Collecting and characterizing landrace populations of Tri folium pratense in Uruguay
Forage legume production is restricted by several environmental constrains,such as drought,flooding,soil acidity, that may affect the establishment,growth and persistence,in spite of the adaptation of naturalized legumes to low fertility soils.The physiologic and morphologic characterization of naturalized populations help to determine the genetic diversity generated by natural selection (biotic and abiotic stresses,grazing, etc) due to several years of on‐farm seed multiplication.This research is part of the research developed by the Project FTG-787/2005:Amplification of the genetic base of naturalized forage legumes for sustainable pastoral systems,financed by FONTAGRO (http://www.inia.org.uy/sitios/lesis/).Landraces (L) of Trif olium p ratense collected from different Uruguayan farming systems were compared with local check cultivars (LC) that were initially introduced by the farmers.
