杂交中稻-再生稻品种筛选试验

Selection Experiment of Hybrid Middle Rice-Ratoon Rice Varieties

以8个杂交中稻品种(含对照)为试验材料,比较分析了各品种作中稻再生栽培头季稻和再生稻抗病性、生育期、产量构成因素及产量表现。结果表明,深两优5814、K优AG、新两优223两季产量比两优6326(CK)增产极显著,适宜作再生稻种植;Y两优1号与CK产量相当,可以适当种植;C两优343、渝优1号、渝优15比CK显著或极显著减产,不适宜在湖北省蕲春县作再生稻种植。

Using 8 hybrid middle rice varieties as test materials,the disease resistance,growth period,yield components and yield performance of the varieties planted as main rice and ratoon rice in Qichun were compared.The results showed that yield of two crops Shenliangyou 5814,K you AG,Xiniangyou 233 was very significantly higher than that of CK,thus was suitable for been planted as ratoon rice.The yield of Y Liangyou 1 equaled to that of CK thus could be planted locally.The yield of C Liangyou 343,Yuyou 1 and Yuyou 15 was significantly lower than that of CK,was not suitable for being planted in Qichun.
