Morphological variation and classification of field-grown Stylosanthes seabrana and S, scabra

摘要

Seventy-eight Stylosanthes seabrana and S. scabra lines were grown at CSIRO Lansdown Research Station, north Queensland and 32 morphological and agronomic characteristics were measured and used as attributes to define similarity groups using the numerical classification program PATN.At the 5-Group level, groups were mostly homogeneous by species. Terminal leaflet shape and terminal leaflet apex shape, the presence or absence of leaflet and stem hairs, the presence or absence of inflorescence bristles, the presence or absence of stipule horn lateral bristles and stipule horn terminal bristles were the most useful attributes defining groups.
