In order to research yield potential of rice varieties with different panicle type, we made an experiment in 2001. Field experiment proved that erect panicle and semi-erect panicle can attain a yield potential of 11 775～12 050 kg/hm 2, has a 18.2%～22.7% yield advantage over common panicle type. The result of cultivation showed that the yield potential of erect panicle and semi-erect panicle rice is higher than common panicle rice.
