(a)～(e): The marked contents are explained in detail in B.2. (w), (s): The marked contents specifically indicate that the standard varieties are winter rapeseed (w) and spring rapeseed (5). (ten): The marked contents are explained in detail in B.3. The underlined parts in this document specifically indicate the applicable scope of the tested traits. 5 Requirements for propagation materials
5.1 The propagation materials shall be provided in the form of rapeseed grains of the same type. 5.2 The number of seeds submitted shall be at least 50)8. 5.3 The seeds submitted shall be healthy in appearance, vigorous, and free of disease and damage. The specific quality requirements for seeds are as follows: purity ≥97.0%, germination rate 285%, moisture content 9.0%
5.4 The seeds submitted shall generally not be subjected to any treatment that affects the normal expression of the variety traits (such as seed coating treatment). If they have been treated, detailed description of the treatment shall be provided.
5.5 The seeds submitted 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 2 independent growth cycles. 6.2 Test location
The test is usually carried out at a location. If some traits cannot be fully expressed at the location, they shall be observed at other qualified locations.
6.3 Field test
6.3.1 Test design
The applied variety and similar varieties shall be planted adjacent to each other: in hole sowing or row sowing: with appropriate plant spacing. Each plot shall have at least 100 plants and 2 replicates. 6.3.2 Field management
It shall be carried out in accordance with the local mountain production management method. 6.4 Trait observation
6.4.1 Observation period
The trait observation shall be carried out according to the breeding stages listed in Table A.1 and Table A.2. See Table B.1 for description of growth stages. 6.4.2 Observation methods
The observation of traits shall be carried out in accordance with the observation methods (VG, VS, MG, MS) specified in Tables A.1 and A.2. For the observation methods of some traits, see B.2 and B.3.
6.4.3 Number of observations
Unless otherwise specified, the number of plants sampled for individual measured traits (VS, MS) shall not be less than 20. When observing the organs or parts of plants, the number of samples taken for each plant shall be 1. The observed traits (VG, MG) shall be observed in the entire plot or in a mixed sample of a specified size. 6.5 Additional tests
If necessary, the traits listed in Table 2 may be used for additional tests on traits not listed in this document. 7 Determination of specificity, consistency and stability of results 7.1 General principles
The determination of specificity, consistency and stability shall be carried out in accordance with the principles specified in B/T 19557.1. 2
7.2 Determination of specificity
NY/T 2439—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 in at least one trait, it can be determined that the applied variety has specificity. 7.3 Determination of consistency
For conventional varieties (including parental lines), a 2% population standard and at least 95% acceptance probability are used, and the observed sample is 200 plants. A maximum of 7 out-of-shape plants can be allowed.
For hybrids, a 10% population standard and at least 95% acceptance probability are used. When the observed sample is 200 plants, a maximum of 27 out-of-shape plants can be allowed.
For other types of varieties, the degree of variation of the variety cannot significantly exceed that of the same type of varieties. 7.4 Determination of stability
If a variety has consistency, it can be considered to be stable. Generally, stability is not tested. If necessary, the next generation of seeds of conventional varieties or newly prepared seeds of hybrids can be planted. Compared with the seeds provided previously, if there is no obvious change in the expression status of the trait, the variety can be determined to be stable. In addition to directly testing the hybrids themselves, the stability of hybrids can also be determined by testing the consistency or stability of their parental lines.
8 Trait table
8.1 Overview
According to the test screening requirements, the traits are divided into basic traits and selected traits. Basic traits are traits that must be used in the test. The basic traits of Brassica juncea are shown in Table A.1, and the selected traits are shown in Table A.2. 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 Types
According to the expression method of traits, 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 breed descriptions. 8.3.2 For quality traits and pseudo-quality traits, all expression states are listed in the test guide; for quantitative traits, in order to shorten the length of the trait, the expression states of even-numbered codes are not listed. The expression states of even-numbered codes are described as the previous expression state to the next expression state.
8.4 Standard Varieties
The trait table lists standard varieties that can be referenced for the expression states of some traits to help determine the different expression states of related traits and correct for differences caused by environmental factors.
9 Grouped traits
In this document, the cultivar grouped traits are as follows: a) Name: Lobe (Character 7 in Table A.1).
b) Initial flowering time (Character 13 in Table A.1). c) Plant: Height (Character 25 in Table A.1). 10 Technical Questionnaire
