摘要
为了筛选出适合山东地区种植的抗旱玉米品种,以37个玉米杂交种为材料,以抗旱指数和抗旱隶属度为依据进行控水试验。结果表明:抗旱性极强品种有鲁单9088、连胜188、天泰33、郑单958,抗旱强的是东单60、三水218、济玉96,德利农988与登海661为不抗旱品种,其它玉米杂交种抗旱性一般或者较弱。
In order to select the suitable drought -resistant maize varieties for Shandong Province , the drought tolerance of 37 maize hydrids was assessed based on subordinate function values ( SV) and drought index (DI).The results showed that Ludan 9088, Liansheng 188, Tiantai 33 and Zhengdan 958 were the highest drought-resistant cultivars , Dongdan 60, Sanshui 218 and Jiyu 96 were medium drought-resistant cultivars , Deli-nong 988 and Denghai 661 were not drought-resistant cultivars, and the others were drought -sensitive cultivars.
