This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents"
Drafting.
This document replaces LY/T 1853-2009 "Guidelines for testing specificity, consistency and stability of new plant varieties"
Compared with LY/T 1853-2009, in addition to structural adjustments and editorial changes, the main technical changes are as follows.
a) The quantity and type of test materials have been changed (see 5.2, 5.3, 4.1.2, 4.1.3 of the.2009 edition);
b) Added the applicable environment of color in the test conditions (see 6.3.2);
c) The description and grouping types of species groups have been changed (see 8.1, 8.2, 6.1, 6.2 of the.2009 edition);
d) Added the standardized description of trait expression status and codes (see 9.4);
e) Added standard varieties and parent information on expression status response, and selected varieties that are more common in breeding and gardening applications in my country
(see 9.5);
f) Added "Plant. Posture", "Leaf. Multiple Color", "Leaf. Secondary Color on Ventral Surface (only applicable to varieties with multiple color leaves)", "Leaf. Secondary Color Type"
(Applicable only to varieties with multi-colored leaves)""Leaf. Cross-sectional shape""Leaf. Glossiness""Leaf. Ventral hair state""Inflorescence. Shape

The ventral side of the lobe has obvious color difference)" "Corolla lobes. back side has colorful rib-like stripes" "Corolla lobes. back side has colorful rib-like stripes"
"Stamens. presence or absence" "Stamens. filament color" "Pistil. length" "Pistil. style color" "Flower. fragrance" "Phenology. leaves neat in autumn
There are 30 traits in total (see Table A.1 in Appendix A);
g) Changed "Leaf. Length", "Leaf. Width", "Leaf. Shape", "Leaf. Young Leaf Ventral Color", "Leaf. Ventral Main Color", "Leaf.
Leaf tip shape”, “Leaf blade. leaf base shape”, “Leaf blade. texture”, “Leaf blade. ventral hair state”, “Petiole. length”, “Inflorescence. number of florets”

The expression status of 24 traits, including anther color, pistil color, stigma color, and phenology, is shown in Table A.1,.2009 edition.
Table A.1);
h) Deleted "Plant. Growth type", "Plant. Plant height", "Current year branch. Scales", "Current year branch. Epidermal hair type", "Current year branch. Hair color"
