Combination Experiment on the Varieties (Strains) of Late Rice in Seed Enterprises in Sanming City

In 2018, 11 varieties (strains) of late rice were introduced into Jiangle County to conduct a combination experiment. By taking Yiyou 673 as the control, the yields and economic characteristics were compared. The results showed that the yield of Juliangyou 5336 per 667 m² was 747.67 kg, which was significantly higher than that of Yiyou 673 in the control group, and the comprehensive characteristics were more prominent, so it was suggested to expand the experimental demonstration. The yield of Hongyou 639 ranked the second, and Guyou 6866, Longliangyou 049, Wutianyou 713, Zhenxian2you 164, Liangyou 2161, Liangyou 3301 and Guang8you 5476 had not significant effect on increasing/decreasing the yields compared with that of Yiyou 673. Therefore, the above 8 varieties were suggested to continue to be experimented, and Shanguyou 3518 was suggested to participate in the experiment of early maturity group.
