The cytological features including chromosome number, karyotypic characteristics, C-banding and silver NOR-banding were investigated in a local cultivar of Allium sativum L.,from Turkey. Actual lengths, relative lengths, US arm ratios of mitotic chromosomes werecalculated from best six metaphase plates. Only Chromosome 5 was submedian, all the otherswere median. C-banding was observed on 4 chromosomes. Bands were centromeric onChromosome 1 and 4, located to the neighborhood of the secondary constrictions onChromosome 5 and were interstitial close to centromere on Chromosome 8. Darkly stained silvernitrate bandings were present in the NORs of Chromosome 5 and 7, on Chromosome 1 and 8 insome cells.
