The variety is characterized by high yield,stable yield,resistance to stripe leaf blight,good quality and strong adaptability. The average yield was 10 511.3 kg/hm² in Hebei rice variety regional tests from 2016 to 2017,increasing by 4.3% than the control variety kenyu 38. The average yield was 9 945.0 kg/hm² in Hebei rice production test in 2017,increasing by 3.5% than the control variety kenyu 38. The average yield was 9 665.3 kg/hm² in the national rice regional tests of Jing-Jin-Tang group from 2017 and 2018,which was 3.9% higher than that of the control Jinyuan 45. The average yield was 9 634.2 kg/hm² in the national rice production test of Jing-Jin-Tang group,which was 4.5% higher than that of the control Jinyuan 45. The rice quality of this variety has reached the national standard of high-quality grade 3 rice. In 2018,it was approved by Hebei Crops Variety Certification Commission（No.:Hebei Rice Certification 20180002）,and the National Crops Variety Certification Commission（No.:National Rice Certification 20200044）.
