摘要: 【目的】研究玉米水旱交替种植模式鉴定法,为准确鉴定玉米抗旱性提供理论依据。【方法】以157份玉米自交系为材料,测定水旱交替种植模式法和常规水旱分区法的三重复的抗旱系数,利用三重复之间的相关系数对比研究两种方法的优劣。【结果】常规水旱分区鉴定的抗旱性,三重复间的相关系数为0.692~0.755(平均值 0.724),而水旱交替种植模式鉴定的抗旱性,三重复间的相关系数为0.835~0.887(平均 值0.861);水旱交替种植模式鉴定法重复间相关系数要高出常规水旱分区鉴定法18.9%。【结论】与常规的水旱分区鉴定法相比,水旱交替种植模式抗旱鉴定法具有更高的准确性和重复性,且便于材料观察的特点,可用于玉米抗旱性大规模鉴定。

Abstract: 【Objective】 To explore the method of alternate cropping pattern of flood and drought identification to provide theoretical basis for accurate identification of maize drought resistance. 【Method】 Using 157 maize inbred lines as materials, the three-repeat drought resistance coefficients of alternate cropping pattern of flood and drought method and conventional paddy-drought zoning method were tested, and the advantages and disadvantages of the two methods were studied by comparing the correlation coefficients between three repetitions. 【Result】 The results showed that the correlation coefficient between three repetitions was 0.692 ~ 0.755 (average 0.724) in conventional identification of flood and drought zones. The correlation coefficient between the three repeats was 0.835 ~ 0.887 (average 0.861) in alternate cropping pattern of flood and drought method. The repeated correlation coefficient of the alternate cropping pattern of flood and drought method is higher than that of the conventional rice-drought zoning method 18.9%. 【Conclusion】 Compared with the conventional method, the method of alternate cropping pattern of flood and drought identification has higher accuracy and repeatability, and is convenient for material observation, and can be used for large-scale identification of maize drought resistance.
