家园 你的理解有点不太精确

首先说明:无意加入挺转还是反转得一方。只是觉得你的理解不太准确。

人家说的是没有增加yield potential.

另外在报告的summary里已经说得很清楚(其中的yields还用黑体加重指出了)。

The adoption of Bt crops increases yields by mitigating yield losses from insects. However, empirical evidence regarding the effect of HT crops on yields is mixed. Generally, stacked seeds (seeds with more than one GE trait) tend to have higher yields than conventional seeds or than seeds with only one GE trait. GE corn with stacked traits grew from 1 percent of corn acres in 2000 to 71 percent in 2013. Stacked seed varieties also accounted for 67 percent of cotton acres in 2013.
