明溪县晚稻新品种筛选与综合性状评价

    Screening and Comprehensive Trait Evaluation of New Late Rice Varieties in Mingxi County

    • 摘要: 为筛选出适合福建省明溪县晚稻生产的高产、抗病、优质的水稻新品种,2024年以宜优673为对照,引进11个晚稻新品种,在明溪县开展品种对比筛选试验,对参试水稻品种的生育期、农艺性状、抗性、产量等指标进行分析。结果表明:明太优7258、萃优712 、辰两优213产量排名前3,产量分别为9 975、9 825、9 787.5 kg·hm−2,比宜优673(CK)分别增产7.43%、6.24%、5.5%,增产效果显著,品种田间综合表现良好,农艺性状优良、抗病性强、产量稳定,建议进入生产试验阶段。禾两优香占、禾两优254、毅两优2165产量分别为9 475.5、9 427.5、9 262.5 kg·hm−2,较宜优673(CK)增产2.27%、1.95%、0.16%,但增产效果均不显著,建议继续参加区域试验。甬优99、田3优闽农占、忠优508、宁12优红6、晶香两优钰禾产量均比宜优673(CK)低,出现减产的情况,建议终止试验。

       

      Abstract: In order to screen out the new rice varieties with high yield, disease resistance and high quality suitable for the late rice production in Mingxi County, Fujian Province, 11 new late rice varieties were introduced to carry out the comparative screening test in Mingxi County in 2024 with Yiyou 673 as the control. Then, the growth period, agronomic traits, resistance and yield of the tested rice varieties were analyzed. The results showed that the yield of Mingtaiyou 7258, Cuiyou 712 and Chenliangyou 213 ranked the top 3, and the yield was 9 975, 9 825 and 9 787.5 kg·hm−2, respectively, which was 7.43%, 6.24% and 5.5% higher than that of Yiyou 673 (CK), respectively, with significant yield increase effect, good comprehensive performance in the field, excellent agronomic traits, strong disease resistance and stable yield. It was recommended to enter the production test stage. The yields of Heliangyou Xiangzhan, Heliangyou 254 and Yiliangyou 2165 were 9 475.5 kg·hm−2, 9 427.5 kg·hm−2 and 9 262.5 kg·hm−2, respectively, which were 2.27%, 1.95% and 0.16% higher than those of Yiyou 673 (CK), but the yield-increasing effects were not significant. Therefore, it was recommended that these three varieties continued to participate in the regional trials. The yields of Yongyou 99, Tian 3 You Minnongzhan, Zhongyou 508, Ning 12 Youhong 6 and Jingxiang Liangyou Yuhe were all lower than that of Yiyou 673 (CK), showing a yield reduction trend. It was recommended that the trials for these varieties should be terminated.
