Combination Experiment on the Varieties(Strains)of Late Rice in Seed Enterprises in Sanming City

2018年在将乐县引进11个晚稻品种(系)进行联合体试验,以宜优673为对照,从产量、经济性状等进行比较。结果表明:聚两优5336每667m2产量747.67kg,比对照宜优673增产达极显著水平,且综合性状表现较为突出,建议扩大试验示范;泓优639产量位居第2位,谷优6866、泷两优049、伍天优713、镇籼2优164、两优2161、两优3301、广8优5476比对照宜优673增减产均不显著,建议以上8个品种(系)继续参试;杉谷优3518建议参加早熟组试验。

In 2018,11 varieties(strains)of late rice were introduced into Jiangle County to conduct a combination experiment.By taking Yiyou 673 as the control,the yields and economic characteristics were compared.The results showed that the yield of Juliangyou 5336 per 667 m 2 was 747.67 kg,which was significantly higher than that of Yiyou 673 in the control group,and the comprehensive characteristics were more prominent,so it was suggested to expand the experimental demonstration.The yield of Hongyou 639 ranked the second,and Guyou 6866,Longliangyou 049,Wutianyou 713,Zhenxian2you 164,Liangyou 2161,Liangyou 3301 and Guang8you 5476 had not significant effect on increasing/decreasing the yields compared with that of Yiyou 673.Therefore,the above 8 varieties were suggested to continue to be experimented,and Shanguyou 3518 was suggested to participate in the experiment of early maturity group.
