欧李品种主要经济性状的灰色关联分析

Grey correlation analysis of main economic characters of Cerasus humilis

以引种成都地区的10个欧李品种为试验材料,假设一个参考品种,选取10个试验品种29项指标的最优值作为参考品种的各项指标,应用灰色关联度分析法对欧李的生长表现进行综合评价.结果表明:10个欧李品种的29项性状指标差异较大;植株生长状况和果实性状指标在综合评价体系中占有重要地位;10个欧李品种生长表现的综合排序为农大7号、燕山2号、燕山1号、鲁1、京欧1号、鲁2、蒙艳早红、内蒙大、16-8、京欧2号;结合关联度分析和综合排序得知,在成都地区,农大7号适合发展为经济兼观赏品种,燕山2号和燕山1号适合发展为经济品种,鲁1、京欧1号、鲁2和蒙艳早红适合发展为观赏品种.建立的评价模型可用于欧李生长表现的综合评价.

10 cultivars of Cerasus humilis from Chengdu area were selected as experimental cultivars. One of them served as the reference cultivar and the optimal values for 29 indexes of 10 experimental cultivars were selected as the reference index. Grey correlation analysis method was used to comprehensively evaluate the growth performance of 10 cultivars. The results showed that the difference in the 29 indexes of 10 Cerasus humilis cultivars was significant. The plant growth situation and fruit traits index played an important role in the comprehensive evaluation system. The comprehensive evaluation of the tested cultivars was listed as Nongda 7, Yanshan 2, Yanshan 1, Lu 1, Jingou 1, Lu 2, Mengyanzaohong, Neimengda, 16-8, Jingou 2. Combined with the correlation analysis and comprehensive sequence, it showed that Nongda 7 was suitable to develop to an economic and ornamental cultivars, while Yanshan 2 and Yanshan 1 were suitable for developing to an economic cultivars. Lu 1, Jingou 1, Lu 2 and Mengyanzaohong were suitable for ornamental cultivars. The established evaluation model can be used for the comprehensive evaluation of the growth performance of Cerasus humilis.
