Other claims from this paper (13)
- Observation Some crosses showed significant positive heterosis for plant height, spike length and 100-kernel weight against better parents.
- Observation The first cross showed significant favorable negative maturity-date heterosis relative to the earlier parent.
- Observation Higher-parent overdominance was found for heading and maturity dates in the first cross.
- Observation Higher-parent overdominance was found for plant height in the second cross and spike length in the third.
- Observation Lower-parent overdominance was found for spike length in the first cross.
- Observation Higher-parent partial dominance was found for maturity date in the second and third crosses and spike length in the second.
- Observation Higher-parent partial dominance was found for grain yield per plant in the first and second crosses.
- Observation Lower-parent partial dominance covered plant height, heading date, kernels per spike, kernel weight and yield in specified crosses.
- Observation Most studied traits showed significant positive inbreeding depression, with stated heading and maturity exceptions.
- Observation Additive gene effects were significant for all traits in all crosses.
- Observation Broad-sense heritability was high to moderate for all studied traits across three crosses.
- Observation Narrow-sense heritability was moderate for most studied traits.
- Recommendation The authors conclude that selection can begin early but would be more effective in later generations.
