Janaki Ammal Biography

(Botanist)

Born: 1897

Born In: Thalassery

Janaki Ammal Edavaleth Kakkat was an Indian botanist best remembered for her work on sugarcane and eggplant. An expert in cytogenetics (the genetic content and expression of genes in the cell), she conducted research on chromosome numbers and ploidy in a variety of garden plants while she was in England which led to new findings on the evolution of species and varieties. Her research played a vital role in understanding the nature of polyploidy in sugarcane and helped in choosing plant varieties for cross-breeding in order to produce the sweetest sugarcane. Born in late 19th century in Kerala, India, Ammal was encouraged to pursue her intellectual interests from a young age. Unlike in many other Indian families of those times where girls were not provided any opportunity for self-development, her family supported her from the very beginning. She developed an early interest in botany and studied the subject at Queen Mary's College and Presidency College. Eventually she realized her interest in cytogenetics and went to the University of Michigan, U.S. for her higher studies. She returned to India after completing her studies and after working as a professor for some time, she joined the Sugarcane Breeding Institute, Coimbatore, as a geneticist. A very determined woman, she never married and dedicated her entire life to scientific pursuits.

Childhood & Early Life
Janaki Ammal was born on 4 November 1897 into a large family in Tellicherry, Kerala, India. Her father Dewan Bahadur Edavalath Kakkat Krishnan was a sub-judge of the Madras Presidency. She had six brothers and five sisters.
She grew up in an era when most Indian girls were not even sent to school and women were discouraged from pursuing their professional interests. However, her family was an open-minded one and Janaki was encouraged to engage in intellectual pursuits.
She developed an early interest in botany. After completing her schooling, she moved to Madras where she obtained a Bachelor's degree from Queen Mary's College. She proceeded to complete her B.Sc Honors from the Presidency College in 1921. While at the Presidency she acquired an interest in cytogenetics.
A brilliant student, she was granted a scholarship to attend the University of Michigan, U.S. from where she earned her MS in 1925.
She returned to India and taught at the Women’s Christian College for a while before going to Michigan again as the first Oriental Barbour Fellow. She completed her D.Sc in 1931.

Career
She returned to India and accepted the post of Professor of Botany at the Maharaja's College of Science, Trivandrum, in 1932.
She joined the Sugarcane Breeding Institute, Coimbatore, as a geneticist in 1934. The institute was created with the aim of improving the Indian sugarcane plant. At the institute, Ammal worked on sugarcane biology with T.S. Venkataraman who had successfully increased the production of sugarcane in the country over the past few years.
Ammal’s research in polyploidy helped to understand the nature of polyploidy in sugarcane. She was instrumental in creating a firm scientific basis for crossing and hybrids, and helped in choosing plant varieties for cross-breeding. She worked at the institute till 1939.
She moved to England in 1940 to work as Assistant Cytologist at the John Innes Horticultural Institution in London. There she performed chromosome studies on a wide range of garden plants, and her studies on chromosome numbers and ploidy led to several new developments in the study of the evolution of species and varieties.
She then worked as cytologist at the Royal Horticultural Society at Wisley from 1945 to 1951. In 1951, the Prime Minister of India, Jawaharlal Nehru, invited her to return to her homeland and help in reorganizing the Botanical Survey of India (BSI).
In 1952, she was appointed as Officer on Special Duty to the BSI, and eventually became the Director-General of the BSI. She went on to serve the Government of India in various other capacities over the ensuing years, including heading the Central Botanical Laboratory at Allahabad.
During the later part of her career, she worked for a while at the Bhabha Atomic Research Centre at Trombay before moving to Madras in 1970 where she was named an Emeritus Scientist at the Centre for Advanced Study in Botany, University of Madras.
Major Works
Janaki Ammal was a pioneer in the field of cytogenetics in India and her contribution to the development of sweeter hybrid varieties of sugarcane has been immense. As a part of the Sugarcane Breeding Institute, she was instrumental in not only analyzing the geographical distribution of sugarcane across India, but also in selecting the best varieties for cross-breeding.
Awards & Achievements
Professor C.V. Raman made Ammal a Fellow of the Indian Academy of Sciences in 1935 and she was elected a Fellow of the Indian National Science Academy in 1957.
