    • 摘要: 为了筛选鉴定出适宜永春县种植的高产、优质、抗性强的杂交晚稻新品种,2022年永春县从广西绿海种业有限公司等单位引进野香优676、更香优703、野香优雅珍、山两优玉丝等9个优质晚稻品种进行筛选试验,以荃优822为对照,通过对各品种生育期、产量及其构成因素、抗逆性等方面进行比较分析。结果表明:山两优玉丝产量最高,产量为7 284.75 kg·hm-2,比对照荃优822增产86.1 kg,增产幅度1.19%,且综合性状表现突出,可扩大示范推广种植。野香优676、更香优703产量位居第2、3位,增产幅度1.04%和0.44%,综合性状表现较好,也可进一步示范推广应用。

       

      Abstract: In order to screen and identify the new hybrid late rice varieties with high yield, high quality and strong resistance which were suitable for being planted in Yongchun County, Yongchun County introduced 9 high-quality late rice varieties, including Yexiangyou 676, Gengxiangyou 703, Yexiangyouyazhen and Shanliangyouyusi, etc., from the units such as Guangxi Lvhai Seed Industry Co., Ltd. in 2022 for the screening test. By taking Quanyou 822 as the control group, the growth period, yield and its component factors, and resistance of each variety were compared and analyzed. The results showed that: the yield of Shanliangyouyusi was the highest, and the yield was 7 284.75 kg·hm-2, which was 86.1 kg higher than that of the control Quanyou 822, with an increase of 1.19%. Moreover, it showed outstanding comprehensive characters, which could be expanded for the demonstration and planting. The yield of Yexiangyou 676 and Gengxiangyou 703 ranked the second and the third, with an increase of 1.04% and 0.44%, respectively. The comprehensive characters were good, so they could be further demonstrated and popularized.
