摘要
采用盆钵栽培法 ,在孕穗期对 12个小麦品种 (系 )进行湿害处理后 ,测定相应指标。利用隶属函数对所测指标进行分析 ,得出各小麦品种 (系 )隶属函数值大小 ,可对各小麦品种 (系 )的耐湿性进行排序 ,也可用聚类分析将各小麦品种 (系 )的耐湿性划为不同的类型。结果表明 ,华麦 8号、D0 41、70 2 3、92 14、8912、鄂麦 12号为高度耐湿 ;宁作13、3778、郑引 1号为中度耐湿 ;宜宾 1号、华麦 9号、鄂恩
wheat varieties were given waterlogging treatment at booting stage, which were cultivated by pots and then determined some indexes. On the base of determined indexes, we had used the subordinate function to analyse it and got the subordinate function value of different wheat varieties. According to the subordinate function value of different wheat varieties, we could know whether the waterlogging resistance of different wheat varieties were high or poor. By the time, we could use the cluster analysis to divide it into different waterlogging resistance type. The results showed that: Huamai 8, D041, 7023, 9214, 8912 and Emai 12 belonged to high wterlogging resistance type; Ningzuo 13, 3778 and Zhengyin 1 belonged to middle waterlogging resistance type;Yibin 1, Huamai 9 and Een 1 belonged to poor waterlogging resistance type.
