In situnuclear DNA content estimations, karyotype analysis, and somatic chromosome number (2n = 16) were made for nine cultivars of fenugreek (Trigonella foenum-graecumL.), revealing cultivar specific chromosomal characteristics and minute structural alterations in chromosomes of the genome. The 4C DNA content varied significantly from 3.12 to 4.36 picograms. Significant variations were also observed in total chromosome length, total chromosome volume, and total form percentage at the cultivar level. Correlation coefficients showed interdependence between the chromosome length and chromosome volume within at the cultivar level. Variations in genomic structure and the nuclear DNA content of fenugreek cultivars, despite the same somatic chromosome number, suggest a genetic drift among the cultivars.
