Screening Test of the Varieties of Late Season Hybrid Rice in Yongding District in 2019

In order to screen out the varieties of late rice suitable for being planted in Yongding District of Longyan City in Fujian Province, five new varieties of hybrid rice, including Shaoyou 766, Wanxiangyou 111, Wanxiangyou 982, Changliangyou 8 and Jingxiangyoubasi, were introduced into Yongding District in 2019. Then, the variety screening test was carried out in the round house section of Xitian Village in Jinsha Township, and Zhongzheyou No.8 was used as the control group to investigate the agronomic traits of various rice varieties, such as the growth period, adaptability, yield, stress resistance, plant and leaf types, etc. The results showed that the yield of Shaoyou 766 was significantly higher than that of the control group, and the yield of Jingxiangyoubasi and Changliangyou No.8 was slightly higher than that of the control group. Therefore, the three varieties were suggested to continue to expand the demonstration area, in order to further observe the agronomic traits, adaptability and stress resistance of each variety. The yield of Wanxiangyou 111 and Wanxiangyou 982 was lower than that of the control group, and had weak disease resistance, short growth period and early ripening period, so they were not recommended to be planted widely in Yongding District.
