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.

The Story

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.
3In 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.
