[目的]探索适宜川南地区推广种植的水稻品种,为川南地区水稻品种选择提供理论依据。[方法]以内香优 10 号、B 优 811、丰两优 1号、宜香99E-4、川香9838 为供试品种,采用随机区组设计,5 个处理,3 次重复,调查记载 5 个品种的生育期,小区实收测产并取样室内考种。[结果]5 个品种的生育期差异不明显。丰两优1 号秧苗粗壮,分蘖能力强,根系生长旺盛,穗粒数、千粒重和结实率高,产量高,综合抗性强; B优811 长势稳定,产量较高,综合抗性良好; 内香优10 号分蘖能力差,千粒重小,结实率低,产量低,综合抗性良好; 宜香 99E-4 和川香 9838 对稻瘟病表现中感且出现部分倒伏情况。[结论]丰两优1 号适宜川南地区的生态环境,可作为川南地区水稻的主推品种,B 优811 可作为推广的辅助品种,内香优10 号、宜香99E-4 和川香9838 不适宜作为川南地区水稻的推广品种。
[Objective] The research aimed to explore rice varieties suitable for popularization in southern Sichuan and provide theoretical basis for rice varieties selection in southern Sichuan. [Method] With Neixiangyou 10, B You 811, Fengliangyou 1, Yixiang 99E-4 and Chuanxiang 9838 as test varieties, randomized block design, 5 treatments and 3 repetitions were conducted. The investigation record 5 A variety of fertility period, the actual production area and sample sampling indoor test species. [Result] The difference of growth period of 5 varieties was not obvious. The seedling of Fengliangyou 1 was thick and strong with strong tillering ability, strong root growth, spike grain number, 1000-grain weight and seed setting rate, high yield and comprehensive resistance. B You 811 grew steadily with higher yield and good comprehensive resistance. Xiangyou 10 had poor tillering ability, low 1000-grain weight, low seed setting rate, low yield and good comprehensive resistance. Yixiang 99E-4 and Chuanxiang 9838 showed some sense of lodging and some lodging in rice blast. [Conclusion] Fengliangyou 1 was suitable for the ecological environment in southern Sichuan and could be used as the main variety of rice in South Sichuan. B You 811 could be used as the auxiliary variety for promotion. Nei Hongyou 10, Yixiang 99E-4 and Chuanxiang 9838 were not Suitable as a promotion of rice varieties in southern Sichuan.
