| 摘 要： | 对生产上推广的抗旱性不同的30个品种,在PVC大棚、旱棚和大田三种条件下,设正常浇水和干旱胁迫两个处理,测定产量;提出品种抗旱性评价胁迫稳产指数概念,并用于分析单一水分胁迫条件和多种水分胁迫条件抗旱评价指标对高产抗旱品种选择的影响.结果表明,在单一水分胁迫条件下,依据正常浇水处理产量和抗旱系数选择高产抗旱的品种,结果不可靠;多种水分胁迫条件下,运用正常浇水产量平均值和胁迫稳产指数选取高产抗旱品种比运用正常浇水产量平均值和抗旱系数平均值选取更可靠,且运算简单,易于在育种工作中运用.通过该法选出的高产抗旱品种有:天泰16、农大81、登海6213、中科11、秀青73-1. |

| Abstract: | The drought and scarcity of water resources are more and more serious, which restrict agricultural development,especially maize production in China.So it is very important to choose cultivars with high yield and drought resistance.30 maize cultivars were planted under the water stress and non-stress treatments designed in PVC shed,drought shed and field,of which the yield was tested under two treatments.A new concept,the stressed stability index(SSI),was brought forward to evaluate the drought-resistance ca... |
