摘要
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50～65cm,窄行密植条件下适宜密度为50万株～60万株,具有5467.95kg/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。
In order to breed semi dwarf soybean new variety to promote cultivation technique of narrow row and thick planting, using United States half-dwarf gennplasm resources resistant to high density, high-oil soybean germplasm in Heilongjiang Province and Hobbit ＇North l lth＇ 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.
