This standard was drafted in accordance with the rules given in GIB/T1.12009. This standard was revised and adopted the Guidelines for the conduct of tests for distinctive, uniform and stability--Rasphcrry\. This standard corresponds to the UP(V Guide TG/43/7, and the degree of consistency with TG/43/7 is non-equivalent. There are technical differences between this standard and the UP(V Guide TG/43/7, the main differences are as follows: - Two species are added, black raspberry (RubusoccicerntaisT.) and raspberry (RutusparnifoliusL.). One trait is added: sepals: stained state,

(a)~~(f): The marked contents are explained in detail in Appendix B. (I) The marked contents are explained in detail in Appendix B. (II) The underlined content is a special reminder of the applicable scope of the test trait. 5 Requirements for propagation materials
5.1 The test materials are one-year-old trees.
5.2 The number of materials to be submitted shall not be less than 10 plants. 5.3 The submitted materials shall be strong, vigorous and free from pests and diseases. 5.4 The submitted materials are generally not subjected to any treatment that affects the expression of variety traits. If they have been treated, detailed descriptions of the treatment shall be provided. 5.5 The submitted materials shall comply with the relevant provisions of plant quarantine in the relevant jurisdiction. 6 Test methods
6.1 Test cycle
The test cycle is at least 2 independent annual growth cycles. The annual growth cycle of a tree refers to the entire period from budding, flowering, fruit ripening and dormancy. Growth and development cycle. 6.2 Test location
The test is usually carried out at a location. If some traits cannot be fully expressed at the location, they can be observed at other locations that meet the conditions.
6.3 Field test
6.3.1 Test design
Please plant the variety and the similar variety adjacent to each other,
with pit planting method, single plant plot, 5 times of measurement, plant spacing 10tt~70cm, row spacing 200cm250cm, 6. 3.2 Field management
Carry out in accordance with the normal production management method of the orchard
6.4 Trait observation
6.4.1 Observation period
Trait observation should be carried out according to the growth stages listed in Appendix A. Appendix 13 explains these growth stages. 6.4.2 Observation method
Trait observation consists of observation methods specified in Appendix A (VG, VS, MG, MS). Some trait observation methods can be found in B.2 and B.3.
6.4.3 Number of observations
Unless otherwise specified, the number of plants sampled for individual observation traits (VS, MS) shall not be less than 5. When measuring the organs or parts of the plants, the sampling efficiency for each plant shall be 2. The group observation traits (VMG) consists of observing the mixed samples of the entire plot or the extended size. 6.5 Additional tests
If necessary, additional tests may be performed on properties not listed in this document. 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 G3T19537.1.7.2 Determination of specificity
The variety in question is clearly distinguished from all known varieties. In the test, when at least one trait of the variety in question has a significant and reproducible difference with similar varieties, the variety in question can be determined to have specificity. 7. 3 Determination of consistency
NY/T2520—2013
When determining consistency, a 1% population standard and an acceptance probability of at least 95% are used. When the sample size is 5 plants, no heteromorphism is allowed. 7.4 Determination of stability
If a variety has consistency, it can be considered that the variety is stable. Generally, stability is not tested. If necessary, the next batch of asexual propagation materials of the variety can be planted. Compared with the previously provided propagation materials, there is no significant change in the expression of the trait, and the variety can be determined to have stability. 8 Trait table
According to the test needs, the traits are divided into basic traits and test traits. Basic traits are traits that must be used in the test. Table A.1 lists the basic traits of trees.
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: qualitative traits, pseudo-qualitative traits and quantitative traits. 8.3 Expression state and corresponding code
8.3.1 Each trait is divided into a series of expression states. In order to define the trait and standardize the description, each expression state is assigned a corresponding digital code to facilitate data recording, processing and the establishment and communication of variety description. 8.3.2 For qualitative traits and pseudo-qualitative 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 state with even-numbered codes can be omitted. The expression state with even-numbered codes can be described in the form of the previous expression state to the next expression state.
8.4 Standard varieties
The table of traits lists the standard varieties corresponding to the expression states of some traits, in order to determine the different expression states of the relevant traits and correct the differences caused by the year and location.
9 Grouped traits
The grouped traits of the varieties in this document are as follows:
a) × young shoots: color of the flower row at the end of the quality (neutral trait 9 in Table A.1). b) * Varieties with point-fruiting type: fruit initial ripening period (neutral trait 21 in Table A.1): or * Varieties with autumn-fruiting type: fruit initial ripening period (neutral trait 22 in Table A1).
) × fruit: color (neutral trait 28 in Table A.1), d) × fruit: fruit type (neutral trait 33 in Table A.1) e) x stem: presence or absence of thorns (neutral trait 44 in Table A.1) 10 Technical questionnaire
