Chromosome numbers of Trifolium species from Romania
Trifolium accessions belonging to 13 clover species have been collected during a joint germplasm collecting mission organized in cooperation between USDA (USA) and ASAS (Romania) and samples were analysed for chromosome numbers. Eleven populations were 2n=14 diploid (T. arvense L., T. campestre L., T. pratense L.), eighteen populations were 2n=16 diploid (T. alpestre L., T. echinatum M. B., T. hybridum L., T. fragiferum L., T. montanum L., T. orchroleucon Huds., T. repens L.), three populations were 2n=4x=32 tetraploid (T. dubium Sibth., T. repens L.) and five were perhaps aneuploids on hexaploid, octoploid (T. medium L.), or higher ploidy levels (T. pannonicum Jacq.) Satellites were clearly identified in T. arvense, T. hybridum, T. orchroleucon and T. pratense accessions.
