# Executive Summary

On November 30, 2007, China notified the WTO of four National Standards
that set quality requirements for legume, cereal, fiber crop, and
oilseed seeds. The main aim is to raise the quality of planting seeds.
These standards will take effect on June 30, 2008 and have a comment
period that closes January 31, 2008. This report contains UNOFFICIAL
translations of the following standards: National Standard for Quality
Grading of Legume Seeds (G/TBT/N/CHN315); National Standard for Seed of
Food Crops/Part One: Cereals (G/TBT/N/CHN316); National Standard for
Seed of Economic Crops/Part One: Fiber Species (G/TBT/N/CHN317);
National Standards for seed of Economic Crops/Part Two: Oil Species
(G/TBT/N/CHN318);

In marketing year 07/08, China's seed imports from the United States are
forecast to increase. Total exports of seeds were \$50.6 million in
MY06/07, up 41 percent from the previous year due to increased
vegetable, grass, and sunflower seed exports. The trade impact of these
new standards on U.S. seed exports to China is unclear. All interested
parties are encouraged to make comments.

Quality Grading of Legume Seeds

**1 Scope**

The present Standard stipulates the indices and the evaluation methods
used for quality grading of legume seeds.

> This Standard applies to the quality grading of legume seeds for
> production, business operations and use. It could be also used as a
> reference for similar plant species of the same sibling.

**2 Standardized Citations**

The clauses of the following documents will become the clauses of the
present Standard by citation. Where the citation annotated with a date,
all the modification made (excluding corrigendum) or any revised version
after such citation will not apply to the present Standard. However all
parties whose agreement is made based on the present Standard are
encouraged to study whether or not to use the latest versions of those
citations. Where there is no any date annotated with the citation, the
latest versions of those citations shall apply to the present Standard.

GB/T2930.1 Sampling, the National Rules on Forage Seed Testing

GB/T2930.2 Crop Purity Analysis, the National Rules on Forage Seed
Testing.

GB/T2930.3 Measurement of other plant seeds, The National Rules on
Forage Seed Testing.

GB/T2930.4 Germination Test, the National Rules on Forage Seed Testing.

GB/T2930.8 Measurement of Moisture, the National Rules on Forage Seed
Testing.

**3 Term and Definition**

The following term and definition are used in the present Standard:

Seed utilization value

The seed utilization value, also called seed utilization rate, shall
mean the percentage of the seeds that can be utilized to germinate among
all the seeds. The calculating formula is as follows:

seed utilization value (%) = crop purity× germination rate×100

**4 Quality Grading**

4.1 The Principle of Quality Grading

Quality grading of the seeds shall be carried out based on the purity,
the germination rate, the number of other plant seeds, and the moisture
of the seeds. The germination rate may include hard seeds. In case the
crop purity and the germination rate are not in the same grade level,
the seed utilization value shall substitute for the crop purity and the
germination rate.

4.2 Testing Method

The testing of the crop purity, the germination rate, the number of
other plant seeds, and the moisture of the seeds shall be carried out in
accordance with the method and procedures set forth in
GB/T2930.1、GB/T2930.2、GB/T2930.3、GB/T2930.4、GB/T2930.8 and the
International Rules for Seed Testing.

4.3 Quality Grading

The legume forage seeds are graded into Grade I, Grade II and Grade III
as Table 1 shows.

**5 The Evaluation Method of Quality Grading**

5.1 Grading of a Single Index

> In accordance with Table 1 the Grading of a single index as the crop
> purity, the germination rate, the number of other plant seed, or the
> moisture of the seed can be determined. The index lower than Grade III
> shall be graded as substandard.

5.2 Grading by Combination of Four Indices

5.2.1 Where all of the four indices of the seed fall on the same quality
grade level as shown in Table 1, the quality grade of the seed can be
determined directly.

5.2.2 Where one of the four indices is lower than Grade III, the quality
of the seed shall be evaluated as substandard.

5.3.3 Where all of the four indices fall at Grade III or above, and the
crop purity and the germination rate are not at the same grade level,
the seed utilization value shall be calculated first, then substitute it
for the crop purity and for the germination rate. Where the seed
utilization value and the number of other plant seeds fall on the same
grade level, the quality grade of the seed shall be determined in
accordance with the grade they fall; where they are not on the same
grade level, the quality grade of the seed shall be determined in
accordance with the grade that the lower index falls on.

**6 Requirements**

6.1 While quality grading is being carried out, the percentage of hard
seeds in the germination rate shall be indicated.

6.2 Seed shall not include any plant seeds of quarantine concern.
