<span style=\"font-size:14px;\">In order to screen suitable early and middle maturing rice varieties in the mountainous areas of southwest Hubei, a formal field plot test was set up in Lichuan City, Hubei Province. The results showed that six varieties, Changnongyou 2521, Enyou 07196, Taoyou 1831, Luoyou 568, Mingzaoyou 673 and Yixiangyou 109, were suitable for popularization in high altitude areas with an altitude of about 1100 m. The yield per mu of these six varieties is more than 500kg, which is significantly higher than that of the control Mianyou 142; The growth period is moderate, not more than 170 days, and can be safely eared before August 20. The possibility of yield reduction caused by “autumn wind” (commonly known as autumn low temperature) is small; high resistance to rice blast, suitable for large-scale promotion in Lichuan city with high incidence of rice blast and regions with similar climate.</span>
