Last Updated: 2024/11/05, The author recently learned from the Bokun Agricultural Research Institute in Yixing City, Jiangsu Province that the "breeding of new japonica rice varieties with multi-resistance, high yield and high quality" carried out by the institute in cooperation with the National Rice improvement Center of the China Rice Research Institute has made a breakthrough. 4701, 4714 and other new high-yield and high-quality japonica rice lines resistant to brown planthopper, rice blast and other diseases and insect pests were successfully bred. It is reported that the new japonica rice lines with high yield and high quality have aggregated genes for resistance to brown planthopper, white-backed planthopper, rice blast and stripe blight, as well as high yield and high quality.

   the author recently learned from Bokun Agricultural Research Institute in Yixing City, Jiangsu Province that the institute and the National Rice improvement Center of China Rice Research Institute have made a breakthrough in the "breeding of new japonica rice varieties with multiple resistance, high yield and high quality" and successfully bred a number of high-yield and high-quality japonica rice lines with resistance to brown planthopper, rice blast and other diseases and insect pests such as 4701 and 4714.

According to   , the new japonica rice lines with high yield and high quality converged genes for resistance to brown planthopper, white-backed planthopper, rice blast and stripe blight, as well as genes specific for high yield and high quality. Tests conducted by the National Rice improvement Center of China Rice Research Institute and the Department of Plant Protection of Agricultural College of Yangzhou University showed that these new high-quality japonica rice lines had obvious resistance to diseases and insect pests such as brown planthopper and rice blast.

High quality japonica rice varieties: 4 in Heilongjiang Province, Longdao 18, Wuyoudao 4, Songjing 28 and Songjing 22; 2 in Jilin Province, Tongxi 933 and Ji Jing 816; 1 in Xinjiang Autonomous region, Jindao 2; 1 in Tianjin, Tianlongyou 619; 1 in Shanghai, Shanghai Ruan12; 1 in Henan Province, Jingjing 3.

Japonica rice is a variety of rice, which is deeply loved by people because of its large grain size, high rice yield and not easily broken during processing. at present, it is planted in Northeast China and the Yellow River Basin, as well as in the south, but it rarely survives because of temperature restrictions.
