Regional Experiment of New Special Rice Varieties for Late Rice in Fujian in 2021 (Experimental Site in Lianjiang County)

In order to screen out the special varieties of high-quality late rice which were suitable for being planted in Fujian Province, the regional comparison experiment of varieties was carried out at the provincial crop variety experimental station in Lianjiang County. The comprehensive performances such as the main agronomic traits, yield, and field disease resistance of 12 new special late rice varieties ( taking Yiyou 673 as the control group) were studied. The results showed that the yield of the rice for special purpose, Lanyou 151, was higher than that of CK, and the yield of Qi 1 You 128 and Nuoliangyou 623 was not significantly lower than that of CK; The yield of Donglianhong No.2 and Ziliangyou 610 was higher than that of CK, and the yield of Hongliangyou 164 was not significantly lower than that of CK. The growth period, agronomic traits and yield structure of these 6 varieties showed good performance, and the comparison experiment could be continued. Yuyama Liangyou 186. The yield of the 6 varieties such as Shanliangyou 186, Nuoliangyou hongjiu, Nuoyou 611, Kunliangyou 8301, Jiliangyou 967 and Zixiang liangyou runxiang decreased significantly or extremely significantly compared with the control group, so it was recommended to terminate the experiment.
