(a): The marked content is explained in detail in B.2 of Appendix 3. (+); The marked content is explained in detail in B.3 of Appendix B. II: The underlined content in this document is a special reminder of the scope of application of the test trait. 5 Requirements for propagation materials
5.1 Propagation materials are provided in the form of seeds.
5.2 The number of seeds submitted is at least 1kg. 5.3 The submitted propagation materials should be healthy in appearance, high in vitality, and free of pests and diseases. The specific quality requirements of propagation materials are as follows: purity ≥ 98.0%, germination rate 285%. Water content ≤ 12%. 5.4 The propagation materials submitted generally do not undergo any treatment that affects the normal expression of variety traits (such as seed coating treatment): if they have been treated, detailed descriptions of the treatment should be provided.
5.5 The propagation materials submitted should comply with the relevant regulations of China's plant quarantine. 6 Test method
6.1 Test cycle
The test cycle is at least 2 independent growth cycles. 6.2 Test location
The test is usually carried out at one location. If some traits cannot be fully expressed at this location, they can be observed at other qualified locations.
6.3 Field test
6.3.1 Test design
Please plant varieties and similar varieties adjacent to each other. At least 150 plants are planted in each plot with a row spacing of 50cm and a plant spacing of 15cm-~20cm. Each test variety is repeated twice. 6.3.2 Field management
The field management plan shall be the same as the field management measures at the test site. The field management of the application variety, similar varieties and standard varieties shall be strictly consistent.
6.4 Character observation
6.4.1 Observation period
Character observation shall be carried out according to the growth stages listed in Table A.1 and Table A.2. The growth stage description is shown in Table A.1. 6.4.2 Observation method
Character observation shall be carried out according to the observation methods specified in Appendix A and Appendix IB (VG, VS, MG, MS): For some character observation methods, see B.2 and B.3.
6.4.3 Number of observations
Unless otherwise specified, the number of samples for individual observed traits (VS.MS) shall not be less than 20. When observing the organs or parts of the plants, the number of samples for each plant shall be 1. The observed traits (VG, MG) of the population should be observed in the whole plot or a mixed sample of a specified size. 6.5 Additional tests
When necessary, the traits in Table A, 2 or the traits listed in this document can be used for additional tests. 7 Determination of specificity, consistency and stability results 7.1 General principles
The determination of specificity, consistency and stability shall be carried out in accordance with the principles determined in GB/T19557.1. 7.2 Determination of specificity
NY/T 2423—2013
The applied variety should be clearly distinguished from all known varieties. In the test, when the applied variety has obvious and reproducible differences with similar varieties and varieties in at least one trait, it can be determined that the applied variety has specificity. 7.3 Determination of consistency
When determining the consistency of the test variety, a 1% population standard and a probability of acceptance of at least 95% are used. When the sample size is 120 plants, a maximum of 3 heteromorphs can be allowed.
7.4 Determination of stability
If a variety has consistency, it can be considered stable. Generally, qualitative testing is not performed. If necessary, the next generation of seeds of the variety can be planted. If there is no obvious change in the expression of traits compared with the previously provided propagation materials, the variety can be determined to be stable.
8 Trait table
According to the test needs, the traits are divided into basic traits and selected traits. Basic traits are traits that must be used in the test. See Table A.1 for the basic traits of adzuki beans and Table A.2 for the selected traits.
8.1 Overview
The trait table lists the trait name, expression type, expression state and corresponding code and standard variety, observation period and method, etc. 8.2 Expression type
According to the expression method of the trait, the traits are divided into three types: quality traits, pseudo-quality traits and quantitative traits. 8.3 Expression state and corresponding code
8.3.1 Each trait is divided into a series of expression states to facilitate the definition of traits and standard descriptions. Each expression state is assigned a corresponding digital code to facilitate data recording, processing and the establishment and communication of variety descriptions. 8.3.2 For quality traits and pseudo-quality traits, all expression states should be listed in the test guide: For quantitative traits, in order to shorten the length of the trait table, the expression states with even-numbered codes can be omitted, and the expression states with even-numbered codes can be summarized in the form of the previous expression state to the next expression state.
8.4 Standard varieties
The table of traits lists standard varieties for reference of expression status of some traits, to help determine the different expression status of the traits and correct the differences caused by environmental factors.
9 Grouped traits
In this document, the grouped traits of varieties are as follows: a) Young stems: epicotyl anthocyanin II color (Table A.1 Neutral trait 1). b) Plants: Growth habit (Table A.1 Neutral trait 9). c) First flowering time (Table A.1 Neutral trait 3). d) Seed: Shape (Table A. 1 Neutral trait 17). e) Seed: Color (Table A.1 Neutral trait 18). Grains: Tremor color (Table A. 1 Neutral trait 21). 3
