Other claims from this paper (12)
- Observation All studied rice characters showed partial and over-dominance.
- Observation Rice crosses had significant positive heterosis for panicle length, panicle number and grain yield.
- Observation The first two rice crosses had highly significant positive heterosis for plant height.
- Observation Non-allelic interactions controlled all studied rice characters in most crosses.
- Observation Additive gene effects were more important for all studied rice characters.
- Observation Dominance and additive-by-additive effects contributed to inheritance of several rice growth and yield traits.
- Observation Additive-by-dominance effects contributed to inheritance of seven rice traits.
- Observation Dominance-by-dominance effects controlled all rice characters.
- Observation Broad-sense heritability estimates were high in rice.
- Observation Narrow-sense heritability estimates were mostly low in rice.
- Association Grain yield was positively correlated with panicle length, panicle number and filled grains per panicle.
- Recommendation The authors recommend crosses I and II for water-deficit rice production and water saving.
