Abstract: Three wide compatibility rice varieties (WCVs) Aus 373, Dular, and LH422 were used to make reciprocal crosses. The spikelet fertilities of reciprocal F₁ derived from Aus373 and Dular with LH422 were significantly different. The means and ranges of the spikelet fertility in F₂ generations were significantly different, too. The spikelet fertility of back crosses with cytoplasm from LH422 was lower, while that with cytoplasm from Aus373 or Dular was higher. It suggested that cytoplasm influenced the expression of wide compatibility genes inthe crosses.

Key words: cytoplasm effect, hybrid fertility, interaction of nucleus and cytoplasm, wide compatibility gene
