A Pioneer of Indian Botany
JANAKI AMMAL
Dr. Janaki Ammal Edavaleth Kakkat (1897–1984) was an Indian botanist, geneticist, and cytologist who is remembered as a pioneer in her field and a trailblazer for women in science in India. Her remarkable life combined path-breaking scientific research, an independent spirit, and a deep commitment to nature conservation.
Early Life and Education: Janaki Ammal was born on November 4, 1897, in Tellicherry (now Thalassery), Kerala, into a family that valued education. Unlike many women of her time, she chose a scholarly life over marriage—a courageous decision in the early 20th century.
She completed her bachelor’s degree at Queen Mary’s College, Chennai, followed by a B.A. (Hons.) in Botany from Presidency College in 1921. She began her career teaching at the Women’s Christian College, Madras.
Her academic brilliance won her a Barbour Scholarship to the University of Michigan, USA, where she earned a Master’s degree in 1925. She later returned to Michigan as the first Oriental Barbour Fellow and completed her D.Sc. in 1931, becoming one of the first Indian women to receive a Ph.D. in the United States.
Scientific Contributions:
🌱 Cytogenetics and Plant Genetics: Janaki Ammal specialised in cytogenetics—the study of chromosomes and inheritance. Her research improved the scientific understanding of plant evolution and genetics.
🌱 Sugarcane Research: Her most celebrated work was at the Sugarcane Breeding Institute in Coimbatore, where she studied chromosome numbers and cross-bred varieties of sugarcane. She developed a high-yielding, sweeter variety of sugarcane suited for India’s climate. This earned her the title “The Woman Who Sweetened India’s Sugarcane” and helped India become self-sufficient in sugar production. She also proved that Saccharum spontaneum, a sugarcane species, originated in India.
🌱 Chromosome Atlas of Cultivated Plants (1945): While working at the John Innes Horticultural Institution in England, she co-authored this landmark reference book with C.D. Darlington. It remains an invaluable resource for plant breeders and geneticists worldwide.
🌱 Magnolias and Ornamentals: At the Royal Horticultural Society, UK, she worked on the cytogenetics of ornamental plants, particularly magnolias. By using the chemical colchicine, she created new tetraploid varieties. The Magnolia Kobus Janaki Ammal, named after her, remains a living tribute to her contributions.
🌱 Other Research: Her studies extended to eggplant, bamboo, medicinal plants, and many other economically important species. Her work deepened the scientific world’s understanding of plant evolution and diversity.
Career and Conservation Work: In the 1950s, after returning to India, Janaki Ammal was appointed as the first Director of the Central Botanical Laboratory of the Government of India in Lucknow. She later served as the Director-General of the Botanical Survey of India and as Scientific Advisor to the Government of India.
She was also a passionate environmentalist. She played a key role in the “Save Silent Valley” movement in Kerala, which protected one of India’s most precious tropical forests from destruction by a hydroelectric project.
Recognition and Legacy:
Padma Shri (1977) – Awarded by the Government of India for her outstanding contribution to science.
E.K. Janaki Ammal National Award (1999) – Instituted by the Ministry of Environment, Forests and Climate Change in her honour, awarded for excellence in taxonomy and biodiversity studies.
Several plant species, including Magnolia Kobus Janaki Ammal, bear her name.
Dr. Janaki Ammal never married, dedicating her entire life to science and conservation. She passed away in 1984, but her green legacy continues to inspire generations of scientists and students alike.
Conclusion: Dr. Janaki Ammal was more than a botanist—she was a visionary scientist, conservationist, and a role model for women breaking barriers in male-dominated fields. From sweetening India’s sugarcane to saving its forests, her life was a testimony to how science, when combined with passion, can transform society.

Worship of the Cosmic Sages
RISHI PANCHAMI
What makes them unique is their dual presence. In mythology, they are revered sages, authors of scriptures, and teachers of gods and kings. In the cosmos, they shine eternally as the seven stars of the Ursa Major (Big Dipper) constellation, serving as celestial beacons. Just as sailors use stars for direction, seekers of truth look to the Sapta Rishis for spiritual guidance.
Names of the Saptarishis
The names of the Saptarishis can vary across different Hindu texts and epochs (Manvantaras). However, a common and widely accepted list for the current Manvantara (the period of time ruled by a Manu) includes:
- Vashistha: Known as a royal priest to King Dasharatha (the father of Lord Rama), he is a symbol of truth, compassion, and the power of prayer.
- Vishwamitra: Initially a king who rose to the status of a Brahmarishi through his intense penance. He is credited with discovering the sacred Gayatri Mantra.
- Bharadvaja: A renowned scholar and the father of Dronacharya, the guru of the Pandavas and Kauravas in the Mahabharata. He is credited with authoring parts of the Rigveda.
- Gautama Maharishi: Known for his righteousness and for discovering Sanskrit mantras. He is also mentioned in both the Ramayana and the Mahabharata.
- Atri: A revered sage known for his deep penance and wisdom. His wife, Anasuya, is an embodiment of purity.
- Jamadagni: The father of Parashurama, an incarnation of Lord Vishnu. He is known for his austere lifestyle and deep spiritual discipline.
- Kashyapa: A cornerstone of Hindu cosmology, he is regarded as the father of the Devas (gods), Asuras (demons), Nagas, and all of humanity.
Other lists may include names like Marichi, Angiras, Pulaha, Pulastya, and Kratu, particularly in texts like the Mahabharata and the Brihat Samhita.
Mythological Importance: The Sapta Rishis are regarded as the seers of the Vedas, transmitting eternal truths to humanity.
They served as gurus of kings, gods, and even avatars, ensuring the continuity of dharma.
Many dynasties and lineages trace their origin to them, making them the patriarchs of civilisation.
Their lives show that even sages faced human struggles, yet rose above them through penance and wisdom.
Cosmic Importance:
1. Stars of Ursa Major: They shine as the seven stars of the Big Dipper constellation, symbolising their eternal presence.
2. Keepers of Time: In each manvantara (cosmic age), a new set of Sapta Rishis is appointed to guide creation, linking them with the cosmic cycle of time.
3. Guides Across Ages: Just as sailors use stars to navigate seas, humanity uses the Rishis’ wisdom to navigate life and spiritual growth.
Rishi Panchami: A Festival in Their Honour
The greatness of the Sapta Rishis is celebrated in the festival of Rishi Panchami, observed on the fifth day of Shukla Paksha in Bhadrapada (August–September).
Purpose: To honour the Sapta Rishis and seek their blessings for purification and wisdom.
Observance: Devotees, especially women, fast on this day, bathe in holy rivers, and worship the Sapta Rishis with offerings of flowers and fruits.
Belief: Observing this vrat (fast) is said to cleanse sins and impurities, granting spiritual merit.
Meaning: It reflects society’s gratitude to the Rishis for preserving knowledge and guiding humanity.
Conclusion: The Sapta Rishis are not just sages of the past; they are eternal symbols of wisdom in both mythology and the cosmos. Their stories reveal lessons of devotion, discipline, justice, transformation, and balance, while their presence as stars reminds us of their timeless guidance.
Through the celebration of Rishi Panchami, devotees continue to honour them, showing that their legacy is alive even today. Whether in the scriptures, the stars, or the human heart, the Sapta Rishis remain cosmic beacons of truth, discipline, and dharma—guiding humanity across the ages.
