The demand for high quality rice with good taste is increasing with the improvement of people's living standard. Many researches have been breeding rice cultivars with improved tasting quality that is tailored for the demands of urban and rural residents in late japonica rice area of the middle and lower Yangtze River. The two rice cultivars Jia 58 and Jia 66 are both derived from crosses of a glabrous rice variety and a late japonica variety. Jia 58 is the progeny of a cross between Jia 0664 and Jia33. Jia 0664 is derived from the America glabrous rice variety Rico No.1, which has a good tasting quality and low-amylose content. Jia 66 is the offspring of WP177 crossed with DC92, another derivative of a glabrous rice variety. Both of our new rice varieties were selected based on their low amylose content(about 10%), good tasting quality, high yield and broad disease resistance. Jia 58 was recommended by Hangzhou city for single-season regional trial in Zhejiang Province in 2011, and the production trial and extended trial were carried out simultaneously in 2012. The variety was approved by crop variety approval committee of Zhejiang Province in 2013. During 2010 to 2013, Jia 58 was planted more than 1,000 hm2.
