摘　　要：研究结果，试验应用的各种鉴定小麦品种抗旱性的方法，其结果基本一致，均有应用价值。田间试验鉴定，结果直观、准确，可靠性强，但耗费的时间、人力和财力多，难以作众多品种的鉴定。在其它方法中，以离体叶片保水力测定最为简便易行，可同时作大批量材料的鉴定；若在离体叶片保水力测定的基础上再进行根系活力测定，鉴定结果会更加可靠。The result shows as follows: Different methods of appraising wheat variety drought resistance have approximately the same resultand practical values. The appraisal result of field test is straight, precise and reliable, but it needs too much more time, manpower and financial resources to appraise many at the same time. In other methods, the preserving water ability test of leaf departed from body is the most simple and easiest, and can be used to appraise many materialsat the same time. With the determination of root vatality, the resultwould be more reliable.
