Zusammenfassung: | Provided is a method of screening for high nitrogen use efficiency wheat cultivars, comprising the following steps: step 1, selecting a plurality of wheat cultivars for testing, carrying out a field test, and setting two fertilization treatment nitrogen supply levels: fertilization treatment without application of nitrogen (N0), and fertilization treatment with normal application of nitrogen (N1); step 2, taking measurements to determine the root system activity and rhizosphere soil enzyme activity of said wheat cultivars under the N0 treatment and the N1 treatment, and carrying out high-throughput sequencing on the soil microorganisms; step 3, analyzing the measurement data of step 2, and screening for wheat cultivars having high root system activity, high rhizosphere soil enzyme activity, a high rhizosphere microorganism richness index and a high diversity index, such cultivars being considered high nitrogen use efficiency wheat cultivars. In the method of screening for high nitrogen use efficiency wheat cu |
