Technical Abstract: Three years after selecting in single-stools in the seedling stage, scientists in the SRU’s sugarcane breeding program assign “HoCP” or “Ho” numbers to varieties advanced for further testing. These newly assigned varieties are planted in replicated nursery trials at the SRU’s Ardoyne Farm in Schriever and the LSU AgCenter’s Iberia Research Station in Jeanerette and Sugar Research Station in St. Gabriel. The year after assignment, varieties advanced for further testing are replanted in nursery trials located on commercial sugarcane farms located in Paincourtville, Cecilia, and Bunkie, each representing a different region of the sugarcane belt. Two years after assignment, active varieties are replanted in three infield tests (Ardoyne Farm and additional commercial farms at Vacherie and Youngsville). In addition, two years after assignment, varieties are introduced to primary stations and outfield locations for testing by the SRU, LSU AgCenter, and the American Sugar Cane League. During the harvest season of 2010, varieties from the 2004 through 2008 Ho and L series were harvested from infield tests at three locations (Schriever, Vacherie, and Youngsville, LA). Varieties from the 2007 through 2009 Ho assignment series were harvested from nursery trials at three locations (Schriever, Jeanerette, and St. Gabriel, LA). In addition to experimental commercial varieties, clones from the USDA Recurrent Selection for Borers (RSB) program were also harvested from these nursery trials.
