Combining speed breeding with gene editing and other technologies is the best way to improve crops. We already have test fields with 3x yield. Getting another 2x would feed more than 20B people. They trick the crops into flowering early by using blue and red LED lights for 22 hours a day and keeping temperatures between 16 and 22 degrees Celsius. They can grow up to 6 generations of wheat, barley, chickpeas and canola in a year instead of only 1-2 crops each year using old farming methods.
