Other claims from this paper (10)
- Observation PCV and GCV were generally larger in F2 than F3–F5.
- Observation Most studied traits had heritability above 50% across generations.
- Method / resource Nine of eleven selection indices were more efficient than direct selection for GY/P in F2.
- Observation IW123 had the highest predicted F2 genetic gain for GY/P, followed by IW2 and other listed indices.
- Observation IW123, followed by IW12 and direct selection, gave highest actual F3 GY/P gains.
- Observation Most indices showed a large discrepancy between predicted and actual GY/P gain.
- Mechanism The authors attributed predicted–actual gain discrepancy to genetic and environmental interactions.
- Observation Direct selection IXW in F3 achieved maximum predicted F3 and F4 GY/P advance, followed by I123.
- Observation I123 achieved maximum actual F3 and F4 genetic advance, followed by IW2 and direct selection.
- Observation Most procedures showed large positive deviations of actual from predicted F3 and F4 gain.
