Average survival and yield of independent transgenic alfalfa plants expressing pMitSOD or pChlSOD in spaced plantings
| Alfalfa Clone | Vector | No. of Independent Transgenics | Survival | Yield |
|---|---|---|---|---|
| % | g/plant | |||
| N4 | Control | 1 | 53 | 34 |
| pMitSOD | 10 | 69 | 50 | |
| pChlSOD | 9 | 69 | 36 | |
| S4 | Control | 1 | 29 | 15 |
| pMitSOD | 13 | 50 | 19 | |
| pChlSOD | 1 | 67 | 52 |
Two parent clones designated as N4 and S4 were transformed with the pMitSOD or pChlSOD vectors. Values are the averages across all independent transgenic plants within a vector with three replications of 5 plants per independent transgenic plant and 15 plants per control. Survival and yield of the transgenic plants were significantly greater than the nontransgenic control plants at P = 0.0243 and P = 0.0159, respectively, according to an orthogonal contrast.
