Evaluation of New Canal Point Sugarcane Clones: 1989-90 Harvest Season

摘要

Twenty-five new Canal Point (CP) clones of sugarcane (9 in plant cane, 8 in first-ratoon cane, and 8 in second-ratoon cane) were grown in replicated experiments and harvested at 9 locations representing 6 soils (Lauderhill, Pahokee, Terra Ceia, and Torry mucks, Pompano fine sand, and Malabar sand). The cane and sugar yields of these clones, complex hybrids of Saccharum spp., were compared primarily with those of CP 70-1133, although CP 72-1210 was also included in all experiments. Each clone was also rated for its reaction to sugarcane rust, Puccinia melanocephala H. Syd. and P. Syd., by natural infection, and to sugarcane smut, Ustilago scitaminea H. Syd., by natural infection and inoculation tests, and for its adaptability to mechanical harvesting by subjective assessment.
