中文摘要:
      基于投影寻踪分类法对40份从法国和菲律宾引进的甘蔗种质进行综合评价。方差分析结果表明,各种质间茎径、单茎质量、蔗糖分等主要工农艺性状均存在显著差异(P<0.01),变异系数介于5.68%~51.55%,变异广泛。对各种质的株高、茎径、有效茎、单茎质量、锤度、甘蔗蔗糖分、蔗汁蔗糖分、简纯度和纤维分等9个主要工农艺性状指标进行投影方向和投影值大小分析,结果表明:投影方向以甘蔗蔗糖分的最高,其后依次为锤度、蔗汁蔗糖分、简纯度、单茎质量和茎径等,株高和有效茎的较低;40份种质投影值大小各异,根据投影值大小,结合聚类分析将40份种质划分为5个类群,各类群投影值介于0.00~2.50,其中,第Ⅳ类群的5份种质资源(FR97–127、FR97–53、VMC95–29、VMC96–169和VMC97–30)综合性状表现优良,可供甘蔗杂交利用。综合来看,投影寻踪分类法可作为大量甘蔗种质资源评价的有效途径。
英文摘要:
      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.
