Narrative
`HC2? is an autotetraploid (2n = 4x = 32) yellow flowered alfalfa germplasm (Medicago sativa subsp. falcata). This germplasm has been selected for increased dry matter yield and fall growth. Three replicates of ten plants each of 32 halfsib families of IAMF102 were planted at the three selection locations in semi-sward plots. Ten plant halfsib family plots were space planted in a 2 by 5 plant grid (30cm between plants). Halfsib family plots were separated from each other by 45cm on the plots long axis and 120cm on the plots short axis. Plants were greenhouse established during May 2004 and transplanted to field locations in August 2004. Plants were clipped and evaluated regularly during the 2005 and 2006 growing seasons. During September (Ames, IA) and October (Arlington and Prairie du Sac, WI) 2006 after the onset of fall dormancy response by the plants plant selection was conducted at all three locations. All plants within a halfsib family were visually inspected; the highest yielding plants within each family were dug up. All plants from a family were lined up and above ground biomass fresh weight was measured on the visually selected plants. Of visually selected plants the best one or two plants per location per halfsib family were brought into the greenhouse. A total of 102 plants were brought in from the field to overwintered in the greenhouse of these 77 plants survived and were transplanted into an isolated crossing block at the US Dairy Forage Research Center Farm in Prairie du Sac, WI in April 2007. Bumblebees (Bombus impatiens) were used to open pollinate plants for several months. Halfsib seed was harvested from individual plants and equal quantities of halfsib seed of 60 of the 77 selected plants were bulked to form syn1 seed. A small quantity of syn1 seed was planted in Idaho in April 2008 were syn2 seed was grown using alfalfa leafcutter bees (Megachile rotundata) and harvested in autumn 2008.
