Janaki Ammal

Janaki Ammal (1897-1984) was an Indian botanist and cytogeneticist, the first woman to earn a doctorate in botany from the University of Michigan, who spent much of her early career at the Sugarcane Breeding Institute in Coimbatore developing sweeter, higher yielding sugarcane hybrids suited to Indian growing conditions, reducing the country's reliance on imported sugarcane varieties. She later worked at the John Innes Horticultural Institution and the Royal Horticultural Society in Britain, co-authoring a landmark chromosome atlas of cultivated plants, before returning to India to become the first female director of the Botanical Survey of India. Her research on plant chromosome numbers and hybridization spanned food crops and ornamental plants alike, and she was also an early advocate for conserving India's native plant diversity against development pressure. She is commemorated in the naming of several plant species she helped identify or classify.
