摘　　要：油6019是中国农业科学院油料作物研究所以中豆32为母本,郑8516为父本,经有性杂交,系谱法选育的夏大豆新品种。2015—2016年参加长江流域夏大豆早中熟组品种区域试验,平均产量3 256.5 kg·hm^(-2),较对照品种中豆41增产7.1%;2017年参加生产试验,平均产量3 121.5 kg·hm^(-2),较对照品种中豆41增产12.1%;2018年通过国家农作物品种审定委员会审定。油6019产量高、籽粒大、抗逆性好、商品性优,适合在长江流域中下游地区种植。2018年在湖北省天门市开展了油6019高产栽培技术集成与示范,高产地块产量可达4 500 kg·hm^(-2)以上。试验表明油6019接油菜茬最佳,适时早播,根据土壤肥力情况保苗16.5万~22.5万株·hm^(-2),初花期化控1次,可创高产,提质增效。You 6019 is a summer soybean variety developed by Oil Crops Research Institute, Chinese Academy of Agricultural Sciences, which was selected by the pedigree selection method from the cross of Zhongdou 32 × Zheng 8516. The average yield was 3 256.5 kg·ha^(-1), and 7.1% higher than that of control variety Zhongdou 41 in the national regional test of Yangtze River Basin. In 2017, the yield was 3 121.5 kg·ha^(-1), and 12.1% higher than that of control variety Zhongdou 41 in the production test. You 6019 was approved by National Crop Approval Variety Committee in 2018, had the characristics of high yield, big seed, good resistance and commodity, and was suitable for planting in Middle-Lower Yangtze Area. The research and demonstration of high-yielding cultural technology were performed in Tianmen, Hubei Province, the yield was more than 4 500 kg·ha^(-1) in some fields. To improve yield and efficiency, You 6019 should be planted into rapeseed stubble, it is necessary to early sow with the density of 165-225 thousand plants per hectare, and chemistry control at initial blooming stage.
