摘要
以2017—2018年组配的119个甘蔗组合为材料,分别在广西的南宁、崇左、来宾同时开展组合评价试验,基于锤重性状进行联合方差分析和遗传参数估计,并采用回归分析和AMMI模型对组合进行稳定性分析。结果表明:不同的组合、环境及组合与环境互作在锤重间的差异均达到了极显著水平(P<0.01);3个试验点锤重的广义遗传率均属于中等偏低水平;崇左、来宾试验点的锤重变异系数较大,南宁试验点的锤重变异系数较小;643、404、575、972、636、144、YC95、1470、755、409、701、832、YC37、579等组合表现出高产、稳产和适应性广的特性;结合锤重和组合入选率综合分析,组合449、YC127、796、YC44、533、570、YC123、391、546、403、YC90、252在南宁试验点的表现为锤重和组合入选率较高;组合643、212、YC61、432、903、YC95、YC44、368、YC83、YC127、YC112、701、411、YC90、YC123在崇左试验点的表现为锤重和组合入选率较高;组合643、404、449、144、403、YC48在来宾试验点的表现为锤重和组合入选率较高。
The experiments of sugarcane combination evaluation with 119 combinations from 2017 to 2018 crossing season were conducted in Nanning, Chongzuo and Laibin of Guangxi province. The complex variance analysis and evaluation of genetic parameters in brix weight were took into account as well as the combination stability was analyzed by the regression analysis model and AMMI model. The results showed that differences of brix weight among combinations, environments and interaction between environments and combinations were both highly significant(P<0.01), and the broad-sense heritability of brix weight belonged to medium level or slightly lower in 3 sites. In both Chongzuo and Laibin, variation coefficients of brix weight were large, but that in Nanning was small. The combinations, 643, 404, 575, 972, 636, 144, YC95, 1470, 755, 409, 701, 832, YC37 and 579 performed high yield, high genetic stability and stronger adaptability. The result of comprehensive analysis in both brix weight and selection rate of combination showed that the combinations 449, YC127, 796, YC44, 533, 570, YC123, 391, 546, 403, YC90 and 252 performed high brix weight and high selection rate of combination in Nanning. The combinations 643, 212, YC61, 432, 903, YC95, YC44, 368, YC83, YC127, YC112, 701, 411, YC90 and YC123 demonstrated high brix weight and high selection rate of combination in Chongzuo. The combinations, 643, 404, 449, 144, 403 and YC48 had high brix weight and high selection rate of combination in Laibin.
