Tianjin successfully bred several new japonica hybrid rice varieties with high yield, multi-resistance and high quality

After several years of research, the Rice Research Institute of Tianjin Academy of Agricultural Sciences has successfully selected 9 new japonica hybrid rice varieties with high yield, multi-resistance and high quality. At present, six new varieties have been identified as high-quality hybrid japonica varieties, with an annual extension area of more than 1 million mu, accounting for 20% of the total area of hybrid japonica rice in the country.

It is understood that the Rice Research Institute of Tianjin Academy of Agricultural Sciences has successfully solved the worldwide problem of hybrid japonica rice breeding through independent innovation, and took the lead in establishing a hybrid japonica rice breeding technology system and seed production system in China, increasing the purity of hybrid seeds by two percentage points and increasing seed production by more than 50% compared with the original technology. It has fundamentally solved the problems of yield, rice quality and seed production that have long plagued the development of japonica hybrid rice at home and abroad, and made a great contribution to the technological progress of rice breeding in China.

At present, the Rice Research Institute of Tianjin Academy of Agricultural Sciences has become the leader of scientific and technological innovation of hybrid japonica rice in China. According to reports, in the past few years, they have successfully bred nine new japonica hybrid rice varieties with high yield, multi-resistance and high quality, including 3you 18, Jinjingza 2, 10 you 18, Zhongjingyou 1, Zhongjingyou 2 and Zhongjingyou 3.

The variety 3 you 18 alone has added 260 million yuan to the income of farmers across the country. At present, more than 2 million mu of hybrid japonica rice has been promoted in Jiangsu, Anhui, Henan, Shandong and other places, making it the largest hybrid japonica rice variety in the country.
