II: The scope of use of this article is particularly clear for testing traits. 5 Requirements for propagation materials
5.1 Propagation materials are provided in the form of seeds,
5.2 The number of seeds to be tested is at least g,
5.3 The submitted seeds are healthy in appearance and free of disease and pests: The specific requirements for seed quality are as follows: 98% net waste, 85% moisture, 8% water secretion.
5.4 The submitted seeds are generally not subjected to any damage to the variety. If the treatment is already done, provide detailed instructions for treatment. 5.5 The submitted supplementary materials shall comply with the relevant provisions of the quarantine of the articles. 6 Test methods
6.1 Test period
The test period is 2 separate growth periods
6.2 Test location
The test is usually carried out in one location. If some characteristics cannot be fully expressed in the location, they can be observed in other locations that meet the conditions:
6.3 Field test
6.3.1 Test design
Please plant the varieties and similar varieties in the field. Plant in rows, and leave no less than 1 seedling in each plot. Plant spacing: 15 cm29 cm, row circumference: 20 cm -~25 cm. Two replicates were set. 6.3.2 Field management
When the product grows to 10 true leaves, interplanting should be carried out. The rest of the time, follow the local standard yield management method. 6.4 Character observation
6.4.1 Observation period
Character observation should be carried out according to the growth stages listed in Table A.1. Appendix 13 explains these growth stages. 6.4.2 Observation method
Character observation should be carried out according to the observation method specified in Table A.1 (VG, VS.Mi, MS): For some character observations, see Table A.2 and 13.3.
6.4.3 Number of observations
Unless otherwise specified: Individual character observations
