灰色关联矩阵及局势决策在马铃薯引种评价中的应用

Application of Grey Incidence Matrix and Situation Decision Method in Introduction and Evaluation of Potato(Solanum tuberosum L.)

利用马铃薯(Solanum tuberosum L.)的抗病性、农艺性状、高产稳产性和商品性等指标对引进的马铃薯品种采用灰色关联矩阵和灰色局势决策法进行综合分析评价。结果表明:商品薯产量达到19 641.6 kg/hm2,且综合排序位于前4和前2的中晚熟及晚熟品种青薯168、948-K、晋薯7号、虎头和中熟品种同薯23号、冀张薯3号都可在当地进行推广种植。为提早上市,在保护地种植可选择商品薯产量达到11 662.2 kg/hm2的中薯3号。

The introduced potato cultivars were comprehensively evaluated from their disease resistance,agronomic traits,high yield and commodity and other indicators by using the grey incidence matrix and grey situation decision.The results showed that the commodity potato yield reached 19 641.6 kg/hm2,the late-maturing varieties of green potato 168,948-K,Jin potato 7,tiger,and the middle-maturing varieties of Tong potato 23,Jizhang potato 3,which ranked in the first four and two orders,can cultivate locally.For the early marketing,medium potato 3,which had the yield of 11 662.2 kg/hm2,can be commodity selected in the protection of production land.
