Abstract:

The exploitation of plant heterosis is an effective approach to increase food production. Heterotic hybrid varieties in major crops such as rice, wheat and cotton can show more than a 20% yield advantage over the best conventional ones under the same cultivation conditions. Difficulties in breeding elite male sterile lines and producing commercial hybrid seed hamper the development of hybrid crops.
