摘要
Meiotic studies were performed on 22 Punica granatum cultivars of Iran considering ploidy level, chiasma frequency and chromosomes association. All the cultivars studied possessed n = 8 (diploid) chromosome number but varied significantly in their chiasma frequency, chromosome pairing and segregation indicating their genomic difference. A low number of quadrivalents were formed in some of the cultivars possibly due to translocations. Cluster and ordination based on Principal Components Analysis grouped those cultivars showing meiotic similarities.
