Description
Jijin Chen and co-authors present a 2025 study on breeding hardier rice for dry regions. The hybrid line they study saves water and holds yield in drought, but three threats hit it hard: blast, bacterial blight, and brown planthopper. The team set out to stack one strong defense gene against each threat into the line's parent stock.
Using marker-guided backcross breeding, they placed all three genes into the parent line. The new line, Hanhui303, kept nearly 97 percent of the parent genome. Standard marker tests could not tell the two lines apart. Field trials showed the new line and its hybrid fought off all three threats. Grain traits and quality matched the parent line. Breeders gain a parent stock that keeps drought strength while standing up to pests and disease.
