摘  要:
The characteristics of 13 nationally-registered hybrid rice varieties of the upper reaches of Yangtze River valley in 2017 were analyzed. The results showed that 13 varieties had all an outstanding perfoemance in the main economic traits and high grain yield. They all reached the third grade of national standards of fine grain quality rice, and among them six reached Grade 1 and six reached Grade 2. Two varieties had moderate rice blast resistance but the other11 were not resistant to blast. Thirteen varieties were all susceptible or highly susceptible to brown planthopper. It is recommended that the breeding of hybrid rice varieties with the resistance of rice blast disease and brown planthopper should be further strengthened in the upper reaches of the Yangtze River valley.
