Other claims from this paper (14)
- Intervention effect Ear traits under drought were phenotypically lower than under normal water regime.
- Association Ear length, ear diameter and weight per ear were positively correlated with grain yield per ear (GW).
- Observation A total of 75 QTL were identified under different water regimes.
- Observation The Ye478×Huangzaosi population carried 20 QTLs for the ear traits.
- Observation The Qi319×Huangzaosi population carried 55 QTLs for the ear traits.
- Observation QTL detected in the Ye478×Huangzaosi population were located on chromosomes 1, 2, 5, 6, 7 and 10.
- Observation QTL detected in the Qi319×Huangzaosi population were distributed on chromosomes 2, 3, 4, 5, 6, 7, 9 and 10.
- Intervention effect Under drought stress the Ye478×Huangzaosi population had only four QTLs, significantly fewer than under normal water regime.
- Intervention effect Under drought stress the Qi319×Huangzaosi population had only nineteen QTLs, significantly fewer than under normal water regime.
- Observation In the joint analysis, only three QTLs had significant interaction with environments.
- Observation The genetic feature of maize ear traits is complex.
- Observation Two congruent QTLs in the Ye478×Huangzaosi population contributed 6.15% to 19.48% of phenotypic variation under different water levels.
- Observation Three congruent QTLs in the Qi319×Huangzaosi population contributed 7.14% to 16.65% of phenotypic variation under different water levels.
- Recommendation The QTL appear little influenced by environment and may be used in marker-assisted selection.
