杂交中稻新组合比较试验

摘要

According to the production situation of middle -season rice in Taoyuan County,14 new middle -season hybrid rice combinations with high yield potential and disease -resistant were introduced and used in variety comparison experi-ment with the CK of Y Liangyou no.1.The results showed that Jing Liangyou Huazhan,T89 You no.1,Jing Liangyou 534, Hui Liangyou 898,C Liangyou 277,Shen Liangyou 2000 are the high yield and multiple resistance combinations,could be popularized in large area production.The yields of Y Liangyou 5867,Hui Liangyou 2000,Shen Liangyou 116,Y Liangyou 689 are no much difference with the CK,could be applied based on the geological conditions,agricultural production level and environmental conditions.%根据桃源县中稻种植实际情况，2015年从有关科研单位和种业公司引进新选育的杂交中稻组合14个，以Y 两优1号作对照进行比较试验。结果表明，晶两优华占、T89优1号、晶两优534、徽两优898、C 两优277、深两优2000六个组合稳产高产能力好，抗病抗逆性强，与对照比较增产幅度较大，可以在生产上推广应用；Y 两优5867、徽两优2000、深两优116、Y 两优689四个组合与对照生产能力相当，可根据地理条件、生产水平、环境条件选择性地慎重采用。
