Expanding crop adaptability to increase planting area: A promising strategy for enhancing agricultural production

The yield gap accurately measures the efficiency of converting the maximum genetic yield into the average yield per unit area, nationally or globally. However, despite continuous advancements in breeding and cultivation technology, yield gap continue to widen in many regions worldwide. Our findings suggest that widespread planting of high-yielding varieties can enhance crop yield per unit area and narrow the yield gap, thereby offering an effective strategy to convert the potential high yield per plant into an overall increase in production.
