Five taxa of Trifolium subterraneum (DV, STG, SA-1, FR and STO) from different Spanish regions have been karyologically studied, taking into account the evolutionary tendencies of the karyotype. Their diploid number 2n=16 and their karyotypical diversity have been evidenced.
A comparative study with previously studied Extremaduran ecotypes and Australian cultivars has also been conducted to determine the degree of evolution of the karyotype of the different taxa of T. subterraneum L.
The haploid number n=8 has been determined for each one of the five taxa studied in this paper.
