Description
The introduction of australian subclover varieties in the mediterranean environments of Europe has had irregular results (Olea et al., 1985). For this reason, important projects in selection and genetic improvement of subclover varieties adapted to these environments are carried out in Spain, Portugal and Sardinia. The selection program used at Badajoz (Spain) has originated ecotypes which have been described by Gomez Pitera (1985) and Gonzalez et al. (1986). These ecotypes have short cycles, high level of hardseedness, high seed production and long flowering period. The final stage in the selection of pasture plants must include the evaluation under grazing. Subclover has a high natural capacity of seed burial and a perfect adaptation to high stocking rates and continuous grazing by its morphological and physiological characteristics (Morley et al., 1965 ; Rossiter, 1966; Katznelson, 1974). The objective of this study was to evaluate the new ecotypes and varieties of subclover under real grazing conditions.
