Abstract

In this research 7 accessions of 2 perennial Trigonella species (5 T. elliptica accessions and 3 T. tehranica accessions) evaluated for forage quality in Estahban Research Station, Fars, Iran. Amounts of crude protein, crude fiber, total ash, fat, calcium and phosphorous were determined. Accessions showed significant differences (P<0.01) for all of the traits. The lowest protein content (10.7%) belonged to accessions 7271 of T. elliptica and 770 of T. elliptica. The highest protein content (14.87%) belonged to accession 5310 of T. elliptica. The highest Ca content (2.5%) belonged to accession 76 of T. tehranica. The highest phosphorous content (0.57%) belonged to accessions 7271 of T. elliptica and 103 of T. tehranica. The highest of crude lipid (21%) belonged to accession of 162 T. elliptica. Cluster analysis classified the accessions into 3 groups and the similarity between accessions was 27.66 percent. The results at this study showed that accession 460 of T. elliptica with the highest protein content and the lowest crude fiber may be introduced as the best accession for forage quality.
