Comprehensive assessment of russian androgenic rice varieties in the territory of China

Under the conditions of breeding, control and competitive nurseries, Russian breeders studied double lines (DH) as candidates for varieties, possessing a complex of economically valuable traits, from which varieties Privolny-4, Sonata and Sonet were selected. Androgenic varieties have a high yield, excellent quality of cereals, are resistant to lodging and shedding, and also show resistance to blast in the Krasnodar rice-sowing zone. Within the framework of Russian - Chinese cooperation, as part of 10 domestic rice varieties, androgenic varieties were sown for a comprehensive assessment in China. Chinese colleagues evaluated Russian rice varieties for biological, morphological and economically valuable traits of plants and grain, for resistance to blast in the breeding base of the Hainan province of China with favorable agro-climatic conditions for rice cultivation. In the course of two-year studies, the variability of the biological characteristics of the plants of the tested varieties, depending on the agro-climatic conditions, was noted. Based on the results of the research, it is planned to develop hybridization schemes for the inclusion of Russian rice germplasm in breeding schemes carried out by Chinese rice breeders.
