Title
Estimates of Genetic Variances in Two Spanish Populations of Maize
R. A. Malvar; A. Ordás; P. Revilla; et al. Crop Science 1996. doi:10.2135/cropsci1996.0011183x003600020013x
Other claims from this paper (10)
- Observation The two maize populations showed similar genetic structure.
- Observation Additive effects accounted for most genetic variance for most traits.
- Observation Dominance variance was large for yield, ear and plant height, and ear length.
- Observation Additive by environment interaction variance was significant.
- Observation Dominance by environment interaction variance was not significant in either population.
- Observation Lodging, ear and kernel traits had broad variation and high heritability and expected selection gains.
- Recommendation An interpopulation selection program could improve grain yield if dominance variance is expressed in crosses.
- Observation Yield lacked significant additive variance.
- Association No correlated response between yield and any other trait is expected.
- Recommendation The authors do not recommend indirect grain-yield selection using yield components.
