Different ploidy levels, diploid (2n=2x=24) to hexaploid (2n=6x=72) have been reported for Acorus calamus, a perennial medicinal plant. According to available information, there is a significant relationship between the ploidy level and essential oil compositions and medicinal properties of this important genetic resource. However, there is no information about the chromosome number of A. calam...

the tribe sophoreae sensu polhill [9,10] is a large and diverse assemblage comprising the ancient and primitive ancestral stocks of papilionoideae. the most frequent chromosome basic numbers in this tribe are x = 11 and x = 9 but chromosome numbers range from x = 8-14 are also known. in this study chromosome numbers and karyotype variation of iranian members of tribe sophoreae are reported. ira...

Chromosome information is an important key for taxonomy, phylogeny and genetic in Trifolium plants. Thus, ten Trifolium species namely T. grandiflorum, T. resupinatum, T. dasyurum, T. campestre, T. tomentosum, T. hirtum, T. scabrum, T. lappaceum, T. stellatum, and T. repens were collected from their habitats in Fars province based on their morphologi...

A cytogenetical study on 13 alfalfa (Medicago sativa) cultivars available in Iranian Forest and Rangelands Genebank was performed in order to obtain basic information on the variability in chiasma frequency/distribution, chromosome association and segregation. Such cytogenetic information is useful for planning hybridization programs. Cluster analysis of meiotic data and ordination of cultivars...
