2018年桂南早稻品种区域试验报告

Report on regional test of early rice varieties in the south of Guangxi in 2018

【目的】为广西品种审定、推荐参加全国南方区试等提供科学依据,加速当地水稻优良新品种的推广。【方法】对12个水稻新品种(组合)进行品种区域试验,试验共设12个处理,以特优7118作对照;采用完全随机区组设计,3次重复。【结果】各参试组合全生育期为123-134d,除中智优161和JK-439分别比对照特优7118(CK)短1d和3d外,其余组合均比对照特优7118长,其中东两优814最长,比对照特优7118(CK)长8d;12个参试品种中有7个品种产量比对照特优7118(CK)增产,增幅在0. 03%-5. 87%之间,其中特优676、特优9983比对照特优7118(CK)增产达极显著水平。【结论】特优676、特优9983比对照特优7118(CK)增产达极显著水平,乾两优野丝占、中智优161比对照特优7118(CK)增产达显著水平,为初选的较好品种。

【Objective】To provide scientific basis for Guangxi variety examination and approval,recommend to participate in the national southern regional trial,and accelerate the promotion of local fine new rice varieties. 【Method】The regional trial of 12 new rice varieties(combinations) was carried out. A total of 12 treatments were set up with Teyou 7118 as control,and the complete random block design was used and repeated 3 times. 【Result】The total growth period of each test group was 123-134 days,except for Zhongzhiyou 161 and JK-439,which were 1 d and 3 d shorter than the control Teyou 7118(CK),respectively. The other combinations were longer than the control Teyou 7118,and the Dongliangyou 814 was the longest,which was 8 days longer than the control Teyou 7118(CK),and the yield of 7 varieties of the 12 new rice varieties(combinations)tested varieties was higher than that of the control Teyou 7118(CK),the increase was 0.03% and 5.87%,and the yield of Teyou 676 and Teyou 9983 was significantly higher than that of the control Teyou 7118(CK). 【Conclusion】The yield of Teyou 676 and Teyou 9983 was significantly higher than that of the control,the yield of Qianliangyou yesizhan,Zhongzhi you 161 was great significantly higher than that of the control Teyou 7118(CK),which was the better variety in the primary selection.
