早熟油菜新品种在衡阳县田间试验表现

Field Performance of New Early-mature Rapeseed Variety in Hengyang County

为筛选适于衡阳县推广种植的三熟制早熟油菜新品种,对湖南农业大学提供的5个油菜新品种(湘油514、沣油847、沣油320、湘油420、湘油104)进行了田间比较试验。结果表明:参试的5个品种均可在5月1日前成熟收割,不影响当地早稻的抛栽,尤其是湘油104比对照丰油730早7 d成熟。5个品种中产量最高的是湘油104,显著高于丰油730。沣油847和沣油320产量与丰油730未达到显著差异,可考虑作为丰油730的替换品种。

In order to screen the early-mature rapeseed varieties that are suitable for popularizing in triple cropping area in Hengyang county,field experiment was carried out with five new rapeseed varieties provided by Hunan agricultural university.
