Dilbagh Singh Athwal
Born 12 October 1928 · Punjab
Died 14 May 2017
Developed high-yielding dwarf wheat varieties that boosted India's agricultural productivity.
🔔 Add birthday reminderDilbagh Singh Athwal was an Indian-American geneticist, plant breeder and agriculturist, known to have conducted pioneering research in plant breeding. He was a professor and the Head of the Department of Plant Breeding at Punjab Agricultural University and an associate of Norman Borlaug, a renowned biologist and Nobel Laureate, with whom he has collaborated for the introduction of high-yielding dwarf varieties of wheat.
✨ A detail that surprised us
The amber color of wheat chapatis beloved across India today is the direct result of Athwal’s modification of Mexican wheat varieties in the 1960s.
1. In 1948, Dilbagh Singh Athwal graduated with a Bachelor of Science in Agricultural Sciences from Punjab University, just a year after India’s independence, stepping into a landscape eager for agricultural innovation.
2. 🌾 By 1955, he earned his PhD in Genetics and Plant Breeding at the University of Sydney, returning to India to lead the Plant Breeding Department at Punjab Agricultural University, where he began tailoring wheat varieties to Indian soils.
3. In 1966, Athwal developed ‘PV 18,’ a wheat variety that paved the way for the Green Revolution in India, followed by the amber-grained ‘Kalyansona’ in 1967, which transformed Indian chapatis from red to gold.
4. 🌍 In 1967, he joined the International Rice Research Institute (IRRI) and became its first deputy director general, contributing to rice varieties like IR20 and IR24 that balanced high yield and grain quality for tropical climates.
5. His efforts in modifying Mexican wheat for Indian tastes involved changing the grain color from red to amber, a feat that overcame initial resistance and shaped the staple diet of millions.
6. 🏆 In 1964, he received the Shanti Swarup Bhatnagar Prize for Science, and in 1975, the Government of India awarded him the Padma Bhushan for his trailblazing work in biological science.
7. After retiring from IRRI in 1977, Athwal continued to influence agricultural policies and research in the United States, including leadership roles at Winrock International.

🌱 What changed because of them
Athwal’s development of high-yielding wheat varieties such as PV 18 and Kalyansona catalyzed the Green Revolution in India, drastically increasing wheat production and food security. His leadership at Punjab Agricultural University and IRRI facilitated international collaborations that introduced disease-resistant, high-yield rice varieties adapted to tropical climates. These breakthroughs helped India transition from food scarcity to self-sufficiency by the early 1970s.
