Technical Abstract: Three years after selection in the seedling stage of the USDA variety program, superior experimental varieties are assigned permanent “HoCP” or “Ho” numbers. These varieties are then planted in replicated yield trials at 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 following year, experimental varieties advanced for further testing are pooled with varieties from the “L” series and planted in replicated nursery yield trials on commercial farms (Paincourtville, Cecilia, and Bunkie) representing different regions of the sugarcane belt. From this stage on, varieties from the SRU and LSU AgCenter are combined in all yield tests. These tests (infield and outfield trials) are weighed yield tests. Two years after assignment, infield trials are planted at three locations (Ardoyne Farm in Schriever and commercial farms located in Vacherie and Abbeville), and varieties are introduced to primary stations and outfield locations for testing by the SRU, LSU AgCenter, and the American Sugar Cane League.
