Database on Chromosome Counts of Plants of Acharya Jagadish Chandra Bose Indian Botanic Garden, Howrah, India


The chromosome numbers of the extant and extinct plants play a significant role in determining the phylogenetic interrelation of different groups. In the post Angiosperm Phylogeny Group system of plant classification era more and more attentions were given in molecular based studies, evidences on plant breeding, intraspecific variation, origin and taxonomic relationship studies of diverse plant group. Exhaustive online database on chromosomal counts have already been developed from various sources. Still, there are many species and genera of plants for which no chromosome count is known. There are countries from which very few counts have been reported. Therefore, there is still a great deal of traditional cytotaxonomic work to be done. The present communication presents 519 records belonging to 343 species, 265 genera and 85 families of Angiosperms of Acharya Jagadish Chandra Bose Indian Botanic Garden, Howrah. The paper also reports 60 plant species with new chromosome counts, which were hitherto not reported either in the Chromosome Counts Database (CCDB) or Chromosome Atlas of Flowering Plants of the Indian Subcontinent.
