چکیده

In the present paper, the cytogenetic study including meiotic chromosome number and behavior along with
pollen viability were performed in 4 populations of Trigonella spruneriana Boiss. This is the first cytogenetic
report of the taxon. All populations are diploid and possess 2n = 2x = 16 chromosome number, which is
consistent with the proposed basic number of x = 8. In addition, some meiotic irregularities observed in
different populations included chromosomes stickiness, B-chromosomes, chromosome bridges resulting from
stickiness, the occurrence of laggard chromosomes, formation of micronuclei in tetrad cells and cytomixis. The
highest and the lowest percentages of pollen viability were observed in populations SPR 658 and SPR 566,
respectively.
