The growth period, yield, resistance, quality and other traits of rice varieties approved by Anhui province from 2008 to 2019 were analyzed. The results showed that, from 2008 to 2019, a total of 314 rice varieties were approved by Anhui province, among them, there are 257 indica rice, accounting for 81.8%, and 57 japonica rice, accounting for 18.2%. The seed industry enterprise is the main body of the breeding unit, and the proportion of the varieties participating in the breeding is as high as 75.2%. Except for the middle japonica rice varieties, the growth period of the approved varieties is generally prolonged, and the performance of the late indica and late japonica rice is more obvious. The yield level shows an upward trend, and the increase of late japonica rice is more significant. The performance of resistance to rice blast is generally ideal. Most varieties are at the level of “medium sensitivity” to “medium resistance”, but the proportion of varieties above “resistance” level is only 3.8%; the performance of resistance to rice false smut is also ideal, most varieties are at the level of “sensitivity” to “medium resistance”, and the varieties above “resistance” account for 38.7%. 83.1% of the approved varieties reached the level 3 or above of the ministerial standard, but only 36.3% of them reached the level 2 or above of the ministerial standard. Therefore, it is necessary to carry out rice breeding around “stronger resistance and better rice quality” in Anhui province.
Key words: Anhui province; rice; variety approval; growth period; yield; resistance; quality
