With Huifengsimiao,Nongxiangsimiao,Guangxiangsimiao,Yuesizhan,Meixiangzhan 3,Meixiangyouzhan 4 as the research materi-als,we carried out planting test by field comparison with one middle rice sowing period in 2021 and one middle rice and one late rice sowing periods in 2022. Results showed that when conventional Indica rice was planted in one middle season,its sowing period was shorter than Fen-gliangyou 4. The growth characters of varieties were stable from year to year. And its yield was lower than Fengliangyou 4. When conventional Indica rice was planted in one late season,tested varieties had similar growth period with Huanghuazhan;yields of Huifengsimiao and Nongx-iangsimiao enhanced compared with Nongxiangsimiao,but those of other varieties reduced. At heading stage,Nongxiangsimiao showed stronger resistance to adverse weather,while Yuesizhan and Meixiangzhan 3 had poorer resistance to adverse weather. Huifengsimiao and Guangxiang-simiao were sensitive to high temperature,and Meixiangyouzhan 4 was middle sensitive to adverse weather.
