| 摘 要： | 采用灰色系统理论分析法对引进的12个马铃薯新品种的7个性状进行综合评价。‘云薯506’和‘兴佳2号’的关联度值均大于0.7,综合性状表现最优,适合在广西种植;‘冀张薯12号’和‘中薯5号’的关联度值均大于0.6小于0.7,综合性状表现一般,有待进一步试验观察;‘中薯17号’和‘云薯401’的关联度值均小于0.5,综合表现较差。品种评价结果与试验地实际表现基本一致,灰色系统理论分析法可用于综合评价马铃薯新品种的优劣。

| Abstract: | The grey system theory was used to evaluate seven characteristics of 12 new potato varieties.The potato varieties ‘ Yunshu 506’ and ‘ Xingjia 2’ had an association degree of greater than 0.7 and were suitable for planting in Guangxi with optimal comprehensive characteristics.The potato varieties ‘Jizhangshu 12’ and ‘Zhongshu 5’ were greater than 0.6 but less than 0.7 in association degree,and need to be further observed with general comprehensive performance.The potato varieties ‘Zhongshu 17’and ‘Yunshu 401’ were less than 0.5 in association degree with the poorer comprehensive performance.The evaluation results were basically consistent with the actual performance of the potato varieties in the experiment.The grey system theory can thus be used for the comprehensive evaluation of the advantages and disadvantages of new potato varieties. |
