Abstract:To evaluate the quality of 40 foreign sugarcane clones from Philipins, we used projection pursuit classification on them. Variance analysis showed that there were significant differences in primary agricultural traits including stem diameter, single stem weight, and sucrose concentration (P < 0.01). The substantial variability within the population, with coefficients of variation ranged from 5.68% to 51.55%. Of nine agronomic traits analyzed (plant height, stem diameter, effective stem, single stem weight, juice brix, sucrose concentration, juice sucrose concentration, juice purity, and fiber concentration), sucrose concentration, juice brix, simplicity of sugarcane, single stem weight, and stem diameter owned high projection direction. While that plant height and effective stem was low. Clones differed in projection values, as the 40 clones were divided into five groups based on projection value and cluster analysis. The projection mean value of each group was between 0.00 and 2.50. Five germplasm resources with good comprehensive characters were identified as FR97-127, FR97-53, VMC95-29, VMC96-169, and VMC97-30, making them good candidates for hybridization efforts. In conclusion, the projection pursuit classification method was an objective and practical method to evaluate 40 introduced sugarcane clones, and provides another option for evaluating large numbers of sugarcane germplasm resources.
