| Abstract | ||
| Clover genus (Trifolium) species are the most important forage species after alfalfa, in Iran. Iran is one of the major centers of genetic diversity of the species. A total of 1501 accessions under 27 species were planted in a field experiment in Karaj. Aagro-morphological traits were characterized according to IPGRI descriptors. High level of diversity was found for the most of agro-morphological traits which were discussed in annual and perennial species, separately. Cluster analysis identified wild species that potentially can be used in the agricultural systems. Annual species were appeared in 4 clusters whereas perennial ones classified into 2 clusters and separated from annual species. T. echinatum, T. purpureum, and T. lappaceum were suggested as more suitable species for using in the agricultural systems. Because of high level of diversity in the primary, secondary and tertiary gene pools for cultivated species, clover collection in the National Plant Gene Bank plays a key role in clover breeding programs in the country. | ||
