| 摘 要： | 为评价37个玉米新品种（组合）的耐旱性潜力，采用4种控水处理对玉米植株性状和产量性状进行了分析评价。结果表明，水分胁迫对穗长、秃尖长、行粒数、百粒重、ASI和单株产量6个性状有显著或极显著影响。水分胁迫使玉米品种抽丝散粉间隔期延长，秃尖变长，结实率降低，行粒数减少，籽粒变小，百粒重下降，单株产量降低。应用模糊数学隶属函数法综合评价分析，‘帮豪玉509’、‘忠玉9号’、D36、BH0310和D30综合耐旱性较强，D23、D3、D26和BH3404综合耐旱性较差。

| Abstract: | In order to evaluate the drought tolerance potential of 37 maize varieties, the author evaluated and analyzed of the plant traits and yield traits in maize by 4 kinds of water supply treatments. The results showed that water stress effects were significant or very significant on 6 traits including spike length, bald tip length, grain number per row, 100 kernel weight, ASI and yield per plant. Water stress could result in the extension of maize ASI, the increase of bald tip length, the decrease of seed setting rate, kernel number per row, 100 grains weight and the yield per plant. Comprehensive evaluation result with fuzzy membership function method indicated that ‘Banghaoyu 509’, ‘Zhongyu 9’, D36, BH0310 and D30 had stronger drought tolerance, while D23, D3, D26 and BH3404 had lower drought tolerance. |
