Narrative
Derived from Alamo, a lowland switchgrass cultivar. The selection protocol involved four cycles of selection, the first three of these being mass selection for low dormancy with respect to seed germination. In the last cycle, the 24 clones whose seed exhibited highest germination were selected and and replanted. Seed was harvested from these outstanding plants and germination percentages were determined over several years. Relative rankings of the clones varied from year to year, but the mean germination of seed of the clones was always significantly greater than that of unselected Alamo. Equal portions of seed of each of the genotypes were combined and constitutes the TEM-LoDorm germplasm. The appearance of these clones in the field was no different than unselected Alamo, and the germplasm should be no different than Alamo in any characteristics except germination behavior.

Pedigree
Description:
Derived from Alamo switchgrass through four cycles of selection, the first three cycles utilizing mass selection for germination of freshly-harvested seed, and the last cycle progeny testing was utilized to identify 24 clones (out of 150) with the greatest germination of freshly-harvested seed.
