摘要：

对2010—2020年吉林省国审水稻品种基本特征特性进行了分析。2010—2020年，吉林省通过国审的水稻品种一共29个，均为粳型常规稻，大部分品种由科研或教学单位育成；区域试验产量、生产试验产量、株高和结实率分别以每年0.42%、0.56%、0.62 cm和0.46%的速度递增；整精米率和垩白度平均每年以0.39%和0.15%的速度递增，而直链淀粉含量、胶稠度则以每年0.02%和2.83 mm的速度递减；稻瘟病抗性以中抗和中感为主，抗性呈逐年下降的趋势。

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.
