Hybrid rice D-You-63, D-You-64, Ging-You-Zhong, Xie-You-64, Wei-You-64, Wei-You-35 and Hua-You-63 have more tillering capability and tiller number over their parents and CK variety ’Shuang-Gui-36’ with positive superdominance heterosis （hp） respectively, but L30lAx R29 has less tillers than the sterile line. Between tiller number and 32P distributed （%） in tillers of Ging-You-Zhong, Xie-You-64, Wei-You-64, Wei-You-35, Hua-You-63 and D-You-63 positive correlation has shown except D-You-64 and L30lA x R29. Negative correlation is between tiller number and 14C distributed （%） in tillers of Ging-You-Zhong, Wei-You-64, Wei-You-35, Hua-You-63 withuot D-You-63 D-You-64. and Xie-You-64, Seedling plant dry weight of D-You-63, D-You-64, Xie-You-64 and Hua-You-63 have exceeded to their parents and CK variety. In seedling plant height Ging-You-Zhong, Xie-You-64, Hua-You-63, D-You-64 have higher than their parents and CK variety.The relationship between the grain yield and seedling plant vigor has been discussed in this paper.
