Abstract: In 2018, Yongding Agricultural Technology Extension Station of Agriculture and Rural Bureau introduced 13 new varieties of late rice to conduct the variety comparison experiments in Weiwu Section of Xitian Village, Jinsha Township. The general performance including the growth period, yield, agronomic traits and economic traits of each variety were investigated with Zhongzheyou No. 8 as the control. The results showed that the five varieties including Jinlongyou 820, Hengyousizhan, Chuanzhongyou 3877, Tianyouhuazhan and Huazhenyou 9113 showed strong adaptability, good resistance, tidy grain surface, good color in late maturity, higher tillering ability and percentage of earbearing tiller, with the plant height being 114.8-124.9 cm, stronger lodging-resistance capability, and the production each 667 m² being more than 600 kg, ranking in the top 5 of the tested new varieties, which could be expanded the introduction or extension of planting in Yongding District. The growth periods of the three varieties including Chuanzhongyou 3877, Tianyouhuazhan and Hengyousizhan were relatively short, which could be promoted and planted in the low altitude area with sufficient light and temperature resources in Yongding District. Jinlongyou 820 and Huazhenyou 9113 could be used as the main cultivars to expand the area to continue the trial planting of middle rice or continuous late rice in Yongding District. However, the yield advantages of the 5 varieties in Ruanhuayou series were not obvious, and the plants were relatively high with poor lodging resistance, which were not recommended to be expanded the extension of planting Yongding District. Also, the two varieties of Jiyouyazhan and Jingliangyouhua were not suitable to be planted in Yongding District, which were not recommended to be introduced.
