Investigation of Agro-morphological Characters between 34 Accessions of Trifolium resupinatum L

Agro-morphological characters in 34 populations of Iranian Trifolium resupinatum L. germplasm, were investigated. 24 traits for each accession were evaluated according to white clover and forage legume descriptors. Data were analyzed by SPSS and Excel softwares. Statistical tendency parameters for agro-morphological characters were calculated. A cluster analysis based on morphological traits separate populations in two different groups that in one cluster there was an only accession belongs to Kurdestan locality. Factor analysis have shown that 61/24% of collection variations were expressed by six factors. Leaflet shape, calyx trichome, the length of leaflet and inflorescence diameter were the most important morphological characters and the weight of 1000 seeds, number of days until to flowering were significant agricultural traits. . Based on these results, it seems that variation in germplasms is independent to geographical distribution. This research showed that there is a high biodiversity for this species in Iran due to the diverse environmental conditions, so that be useful for breeding programs and marketing.
