Other claims from this paper (6)
- Association Symbiotic nitrogen reliance accentuated plant-to-plant variation in the hexaploid line.
- Observation Plant variability attributable to symbiosis was stronger with CC231a than with CC283b.
- Intervention effect Selecting seedlings inoculated with the intermediately effective strain using within-tube traits increased later pot dry matter over unselected plants.
- Observation Selected seedlings inoculated with the intermediately effective strain were as productive as those inoculated with the highly effective strain.
- Intervention effect Under the highly effective strain, selection yielded very little extra pot dry matter relative to unselected plants.
- Recommendation The authors concluded within-tube symbiotic selection succeeds only when symbiosis accounts for substantial plant variation.
