利用美国矮源创新半矮秆耐密植、超高产大豆‘合农60号’

为了选育半矮秆大豆新品种推广窄行密植栽培技术，采用美国半矮秆耐密植、高油大豆种质资源Hobbit与黑龙江省优良种质‘北丰11号’配制杂交组合，进行半矮秆耐密植大豆种质资源创新研究，育成半矮秆大豆新品种‘合农60号’。结果表明，‘合农60号’，具有半矮秆耐密植，株高50~65 cm，窄行密植条件下适宜密度为50万株~60万株，具有5467.95 kg/hm2的超高产潜力，脂肪含量22.25%，抗病能力强等突出优点，具有广阔的推广应用前景。

Breed Semi-dwarf, Resistant High Density and Super High-yielding Soybean Variety 'Henong 60' Using American Dwarf Source as Hybridization Paternal

In order to semi dwarf soybean new variety breeding to promote cultivation technique of narrow row and thick planting, using United States half-dwarf germplasm resources resistant to high density, high-oil soybean germplasm in Heilongjiang Province and Hobbit ''North 11th'' preparation of hybrid combination, researching for semi dwarf compact planting of soybean germplasm, improved semi dwarf soybean new variety ''Farm 60th''. The results showed that, ''Farm 60th'', with half-dwarf compact planting, plant height 50-60 cm, under the conditions of narrow row and thick planting suitable density was from 500 thousands plants to 600 thousands plants. With 5467.95 kg/hm2 high yield potential, 22.25% fat content, disease resistance, and other distinctive advantages, had a good prospect of application and extension.
