For 'Tiancheng 7'， the yield ranking was Hengyang > Yongzhou > Zhangjiajie > Changsha > Shaoyang.For 'Xiangxia 2402'， the yield ranking was Yongzhou > Changsha > Zhangjiajie > Shaoyang > Hengyang. For both varieties，the seed germination rate，germination index，and vigor index followed the trend of Zhangjiajie > Changsha > Shaoyang > Hengyang > Yongzhou.
