Crop Improvement
Sorghum is one of the toughest crops around, thriving in drought and poor soil where corn and wheat struggle, so the breeding tricks that made it more productive in China offer a blueprint for climate-resilient gardening and farming everywhere.
Sorghum is a hardy grain crop that handles heat and drought better than most cereals, making it a lifeline in dry regions. Chinese researchers figured out how to breed sterile sorghum plants that could only be pollinated by chosen partners, letting them mass-produce hybrid seeds with better yield and quality. This review looks back on six decades of that work and what it means for future food security.
Key Findings
Three-line hybrid sorghum breeding system has been in use in China for 60 years
Cytoplasmic male-sterility (CMS) systems enabled large-scale production of high-performing hybrid seeds
Dwarf breeding combined with continuous variety renewal drove major yield and quality gains
chevron_right Technical Summary
Chinese scientists spent 60 years perfecting hybrid sorghum breeding, using a technique called cytoplasmic male-sterility to create high-yield hybrid seeds at massive scale, which helped feed people in dry, tough-to-farm regions.

Sorghum bicolor, commonly called sorghum and also known as broomcorn, great millet, Indian millet, Guinea corn, jowar, or milo, is a species in the grass genus Sorghum. It is typically an annual, but some cultivars are perennial. It grows in clumps that may reach over 4 metres (13 ft) high. The g...
