Abstract: The F1 heterosis and fertility of combinations of LH422 or 02428 with Indica or Japonica and combinations of Indica with Japonica were inspected in this test.The results showed that F1 of M-201/Nihonmasari had a quite stronger heterosis on tillers per plant and grains weight per plant,F1 of WCVs with Indica or Japonica were of higher heterosis and of stronger fertility and would promote the rice output obviously, and LH422 had a stronger tendentiousness to Japonica,but 02428 has also a strong tendentiousness to Indica.

Key words: heterosis;F1;fertility, WCVs
