Abstract

The characteristics of national-certified rice varieties in Jilin Province from 2010 to 2020 were analyzed. From 2010 to 2020, a total of twenty-nine rice varieties passed the national certified in Jilin Province, all of which were japonica conventional rice, most of which were bred by scientific research or teaching institutions. The regional trial yield, production test yield, plant height and seed setting rate increased by 0.42%, 0.56%, 0.62 cm and 0.46% per year, respectively. The head rice rate and chalkiness increased at an average rate of 0.39% and 0.15% per year, while the amylose content and gel consistency decreased at a rate of 0.02% and 2.83 mm per year. Rice blast resistance was dominated by moderate resistance and moderate sensitivity, and the resistance showed a decreasing trend year by year.
