Evaluation of cytogenetical and morphological diversity of some Iranian Trigonella foenum-graceum

Karyotypes of eleven Iranian populations of Trigonella foenum-graceum were investigated. Somatic chromosome numbers of examined populations were determined as 2n = 14. Chromosomal parameters were examined as follows: Long arm length (TL), Short arm, total chromosome length, arm ratio, r-value, form percentage of chromosome, total form percentage of karyotype. Chromosomes were mostly metacentric, but some submetacentric chromosomes were also observed. The genotypes number 3, 4, and 6 were classified into symmetric class of 2A and others stand to 1A. The Results of analysis of variance based on completely randomized design (CRD) showed a significant differences among the genotypes for all traits (P<0.01). Cutting dendrogram resulted from cluster analysis (UPGMA) based on 9 parameters.
