Other claims from this paper (13)
- Observation Yield heterosis was the largest among the yield-related traits in the soybean F1 hybrids.
- Observation Heterosis for number of pods per plant and seeds per plant was the next largest after yield heterosis.
- Observation No obvious heterosis was observed for 100-seed-weight.
- Association Traits with high F1 heterosis showed high inbreeding depression in F2 and F3 generations.
- Observation No obvious hybrid heterosis was observed for maturity and quality (protein and oil contents) traits.
- Observation Significant GCA×Generation and SCA×Generation interaction was found for yield.
- Association Parental cultivars with high F1 combining ability were not necessarily high in combining ability in derived inbred generations for yield.
- Observation No significant GCA×Generation or SCA×Generation interaction was observed for quality traits.
- Association F1 combining ability could predict combining ability in derived inbred generations for quality traits.
- Association Yield of the parental materials per se could not be used as an indicator of their GCA.
- Observation Yield heterosis declined in F1-derived generations.
- Recommendation Yield heterosis carried into F1-derived generations is not useful in production.
- Recommendation Selection pressure should be placed on early hybrid generations to improve quality traits in line cultivars.
