Title

M. T. El. Shehab El Deen; M. S. Genedy; A. M. Sharshar Journal of Plant Production 2026. doi:10.21608/jpp.2026.455650.1551
Other claims from this paper (7)
- Observation Some F2 individuals exceeded the parental limits, suggesting transgressive segregation.
- Observation Scaling tests showed many traits were influenced by gene interactions (epistasis), so simple additive models were inadequate.
- Observation All traits were governed by additive and non-additive effects, with dominance more pronounced than additive effects in most cases.
- Observation Broad-sense heritability estimates were generally elevated.
- Observation Narrow-sense heritability was low to moderate.
- Observation Expected genetic advance was small to moderate across most characteristics.
- Observation The F1 of the third cross (Misr4 x Line1) had the highest mean grain yield and superior component performance.
