Technical Abstract: Scientists with the Sugarcane Research Unit (SRU)’s sugarcane breeding program assign permanent “HoCP” or “Ho” numbers to varieties advanced for further testing three years after selection from single-stools in the seedling stage. Researchers then plant these varieties in replicated nursery trials at the SRU’s Ardoyne Farm in Schriever and at 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 planted in nursery trials 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 planted in three infield (weighed yield) tests. One test is planted at Ardoyne Farm, the other two are located on commercial farms in Vacherie and Youngsville. Because there were no weighed yield tests in the southwestern area of the sugarcane industry, a test normally planted in Youngsville was planted in Erath in 2011. 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.
