Within the framework of the signed cooperation agreement between the Belarusian State Agricultural Academy and the Northwestern University of Agriculture and Forestry (China), an agrotechnopark has been created. In September 2019, China provided wheat seeds. The analysis of sowing qualities and grain quality was carried out in the seed quality testing laboratory of the Belarusian State Agricultural Academy, which was accredited by the Belarusian State Accreditation Centre for compliance with the requirements of GOST ISO/IEC 17025-2019.

The quality indicators of Chinese wheat seeds before sowing are given in table 1.

The analysis of the germination energy showed that the wheat seeds had high germination energy of 92.8 %. The indicator shows a high probability of obtaining even sprouts in the field.

Seed germination means the number of normally germinated seeds in a sample taken for analysis, expressed as a percentage [1, 2].

The laboratory germination rate was 95.7 %, and the sowing validity was 97.4 %. The damage to the embryo was 1.27 %, to the endosperm — 2.63 %. Infection with pathogens did not exceed 3 %, no pests were found in the seed material. All of the above indicators confirm the high quality of the seed material.

After harvesting, we analyzed the quality indicators of wheat grain that we got from China in 2019 and the wheat varieties of the 2020 harvest (table 2).

The weight of 1,000 grains characterizes the grain size, as well as its density, the larger the grain and the more complete it is, the greater its weight. Full-scale weight is the weight of 1 litre of grain, expressed in grams. This indicator is closely related to the completeness and density of the grain, as well as its size and shape [2].

The weight of 1,000 grains in the studied varieties ranged from 29.8 g (Arctis) to 37 g (Chinese wheat during winter sowing). Before sowing, the weight of 1,000 grains of Chinese wheat was slightly lower — 34.45 g.
