| 中文摘要: |
| 通过水分和N胁迫下玉米不同杂交种抗旱耐瘠性的试验研究,选择与抗逆性密切相关的9个性状的抗逆系数、抗逆指数为指标,以各指标隶属度为评定标准,分析评价参试品种的抗逆性。结果表明:黔玉3号、黔2599、遵玉3号、黔2411、贵毕302、中单2号和兴黄单89-2的抗逆性表现较好,黔单10号、黔西4号、安单136、黔2451和黔玉1号表现较差。以产量抗逆系数、产量抗逆指数、各性状抗逆系数隶属度及各性状抗逆指数隶属度4个参数进行综合鉴定评价,均得出了基本一致的结果,表明这些参数指标可以作为玉米抗逆性的有效评价参数。 |
| 英文摘要: |
| Based on the field experiment, the adversity resistance coefficients (AC) and adversity resistance indexes (AI) of 9 different morphological and productive characters were used to study the adversity resistance of different genotype hybrid maize varieties under water and N-stress condition, by using the method of subordinate function. The results indicated that Qianyu3, Qian2599, Zunyu3, Qian2411, Guibi302, Zhongdan2 and Xinghuangdan89-2 were drought and barren resistant varieties, but Qiandan10, Qianxi4, Andan136, Qian2451 and Qianyu1 were adversity susceptible ones. The results of comprehensive evaluation by AC of yield, AI of yield, subordinate function value of AC, and subordinate function value of AI were basically consistent. It was suggested that these parameters be adopted to appraise the ability of adversity resistance in maize. |
