This standard was drafted in accordance with the specification (B7T1.1-2009). This standard was modified using the guidelines of the International Union for the Protection of New Varieties of Plants (T10V)\TG/182/3. Guidelines I or the: tonduct of tests for distinetneas, urilerrnity and slability --Guzmania\. This standard does not correspond to the L1)V guideline TG/182/3, but the degree of consistency with TC/182/3 is equivalent. This standard has technical differences compared with the UPOV guideline TG/182/3, mainly as follows: 1. Add "Leaf:. Upper and lower color pattern" and "Inflorescence: shape" for a total of 2 traits: in the test table, add "Leaf: Difference in primary color between bracts and non-flowering leaves", "Flowers first leaflets: with or without secondary color at the tip" and "Applicable to varieties with secondary color at the tip, flowers first leaflets: secondary color at the tip" for a total of 3 traits.
This standard was proposed by the Science and Technology Education Department of the Ministry of Agriculture. This standard is under the jurisdiction of the National New Variety Testing Standardization Technical Committee (SAC/TC277). Drafting units of this standard: [Haixian Flower Port Enterprise Development Co., Ltd., Shanghai Academy of Agricultural Sciences, Ministry of Agriculture New Variety Testing (Shanghai) Branch Center 2, Ministry of Agriculture Science and Technology Development Center. The main drafters of this standard are Zhao Caibiao, Gu Junjie, Liu Ping, Chu Gongdu, Zhang Lianliang, Huang Zhicheng, Li Shouguo, Du Yuanyuan, Chu Hairong, Yi Changhong, Liu Hongye, Zheng Ning.

(a)~(bh): The markings are explained in detail in B1. (X): The marked contents are explained in detail in B.2. The underlined contents in this document are special reminders of the scope of application of the tested traits. 5 Requirements for propagation materials
5.1 Propagation materials shall be provided in the form of seed sheets
5.2 The number of seedlings submitted shall not be less than 50. 5.3 The submitted seedlings shall be healthy in appearance, free from diseases and insect pests, and meet the quality requirements of the flower induction cultivation for seedlings. 5.4 The submitted propagation materials shall generally not be subjected to any treatment that affects the normal expression of the variety traits. If treated, detailed descriptions of the treatment shall be provided.
5.5 The submitted propagation materials shall comply with the relevant provisions of China's plant quarantine: 6 Test methods
6.1 Test cycle
The test cycle shall be at least one independent growth cycle 6.2 Test location
The test is usually carried out at one location. If some traits cannot be fully expressed at one location, they can be observed at other locations that meet the conditions.
6.3 Field test
6.3.1 Experimental design
Please place varieties and similar varieties next to each other. In the greenhouse, the plants are grown in substrates and potted, with one plant in each pot and at least 10 to 20 plants of each variety. When designing the experiment, it should be ensured that after sampling the plants or plant organs, there are enough plants or plant organs to ensure subsequent observation. 6.3.2 Field management
The substrate has good air permeability and drainage, and the growth conditions and cultivation techniques can ensure the full expression of the characteristics of the fruit variety. Management measures can be carried out according to local conventional production management methods. 6.4 Character observation
6.4.1 Observation period
All characters to be observed must be observed during the flowering period. 6.4.2 Observation method
6.4.2.1 Character observation should be carried out according to the observation methods (VC, VS.MG.MS) specified in Table A.1 and Table A.2. For the methods of observing some traits, see B.1 and B.2.
6.4.2.2 When testing the color with a colorimetric card, it should be done in a room with artificial sunlight or a room with sunlight. The spectral distribution of the artificial lighting device should comply with the recommended daylight D6500 standard and the first part of the British Standard 5. All observations should be made by placing the tested part of the plant on a white background. 6.4.3 Number of observations
Unless otherwise specified, the number of plants for individual observation of traits (VS, MS) should not be less than 10. When measuring the organs or parts of the plants, the number of samples for each plant should be 1. For group observation of traits (VGMG), the entire plot or a mixed sample of a specified size should be observed. 6.5 Additional tests
If necessary, additional tests may be performed on the properties listed in Table A, 2 or properties not listed in this document. 2
7 Determination of specificity, consistency and stability results 7.1 General principles
Specificity, consistency and stability shall be determined in accordance with the principles specified in G13/T195.7.1. 7.2 Determination of specificity
NY/T2556—2014
The applied variety shall be clearly distinguished from all known varieties. In the test, if the clear variety has a significant and reproducible difference with the similar variety in at least one property, the applied variety shall be determined to have specificity. 7.3 Determination of consistency
When determining consistency, the population standard of 2 and the acceptance probability of at least 95% shall be adopted. When the sample size is 10 to 18 strains, at most one heteromorphic strain can be allowed. When the sample size is 19 to 20 strains, at most two heteromorphic strains can be allowed. 7.4 Determination of stability
If a variety has consistency, it can be considered stable. Generally, stability is not tested. If necessary, the next batch of seedlings of the variety can be planted. Compared with the previously provided propagation materials, if there is no obvious change in the expression of the trait, the variety can be determined to be stable.
8 Trait table
According to the test needs, traits are divided into basic traits and optional traits. Basic traits are traits that must be used in the test. See Table A.1 for basic traits and Table A.2 for optional traits.
8.1 Overview
The trait table lists the trait name, expression type, expression status and corresponding code and standard variety, observation period and method, etc. 8.2 Expression type
According to the expression method of the trait, traits are divided into three types: quality traits, pseudo-quality traits and quantitative traits. 8.3 Expression states and corresponding codes
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 numeric 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 instructions: For quantitative traits, in order to shorten the length of the trait table, expression states with even codes may not be listed. Expression states with even codes may be described in the form of the previous expression state to the next expression state.
8.4 Standard varieties
The trait table lists standard varieties that can be used as reference for the expression states of some traits to facilitate the determination of different expression states of related traits and the correction of differences caused by environmental factors.
9 Grouped traits
In this document, the variety grouping traits are as follows: a) * Planting: height (trait 1 in Table A.1). b) * Inflorescence: Position relative to leaves (Table A, 1 Neutral Character 15) c) * Inflorescence: Shape (Table A.1 Neutral Character 16). d) * Bract: Main color of upper surface (Table A.
