The cytological section in Botanical Survey of India came into existence on April, 13, 1954 on the recommendation of Dr. E.K. Janaki Ammal, the Officer-on- Special Duty for reorganization of the Botanical Survey of India. She took active interest and initiated a programme of preparing ‘Chromosome Atlas for the Flora of India’. She also made extensive cytotaxonomical studies of Rouvolofia and aquatic genus like Nymphea. Till late nineties, the cytology section under Central Botanical Laboratory was actively engaged in the Chromosomal Survey of Indian flora and in other applied aspects of cyto-chemical investigations. Later on, due to the superannuation of official staff, this section became nonfiction. The work of this section has led to determination of more than 1100 chromosome number of which more than 120 reports are recorded for the first time. More than 100 scientific papers on cytotaxonomy, cytoecology, cytochemistry, and others have been published from this section. As per recommendation of constituted committee Headed by Prof. H.Y. Mohan Ram & Prof. C.R. Babu as member and efforts of Director, Botanical Survey of India this section was restarted in 2015 at Central Botanical Laboratory, Howrah. Till now 03 scientific projects were successfully completed. At present this section is functional at CBL, BSI, Howrah; BSI, CRC, Allahabad, BSI, NRC, Dehradun and BSI, WRC, Pune.
