Screening and Comprehensive Evaluation of the New Hybrid Rice Varieties with High Quality in Longyan City

In order to screen out the high-quality hybrid rice varieties which were suitable for being planted in Xinluo District of Longyan City, six new varieties of hybrid rice with high quality were selected to carry out the comparative test with Huifengyou 3301 as the control group in 2023. Then, the yield, growth period, main agronomic traits, plant growth traits and field resistance of each tested variety were comprehensively analyzed. The results showed that the real-cutting yield of Yexiangyou 699 was 9 622.5 kg·hm⁻², which was 15.6% higher than that of Huifengyou 3301, and the resistance was better. The real-cutting yield of Tailiangyou 217 was 8 712.0 kg·hm⁻², which was 4.69% higher than that of the control group Huifengyou 3301, and the resistance was better. The real-cutting yield of Quanyou 967 was 8 259.0 kg·hm⁻², which was equivalent to that of the control group, but the resistance was better. These three varieties were recommended to continue to expand the demonstration area, thus to further observe the agronomic traits, adaptability, and stress resistance of each variety. The yield of the three varieties, such as Taifengyou 208, Zhenliangyou Yuzhan and Longwang Liangyou 889, was lower than that of the control group, and the disease resistance was weak, the growth period was short, and the maturation period was early. Therefore, they were not recommended to be planted as the middleseason rice and post-tobacco rice in Xinluo District.
