Abstract
Abstract — In this study, karyotype analyses of the six species of Trigonella L. were examined. Chromosome lengths were determined between 1.29–1.74 μm in Trigonella astroites Fischer & C.Meyer, 1.06–1.44 μm in Trigonella fscheriana Ser., 1.67–2.59 μm in Trigonella velutina Boiss., 0.98–1.49 μm in Trigonella cretica (L.) Boiss., 1.16–1.81 μm in Trigonella coerulescens (M.Bieb.) Hal., 0.99–1.72 μm in Trigonella procumbens (Bess.) Rchb., respectively. All species are diploid with 2n = 14,16 and 18 chromosomes and the karyotypes of all species consist of metacentric chromosome pairs. Trigonella velutina has only satellites on the long arms of chromosome 2 and 6. The karyotype analysis of these species was frst time counted in Turkey.
