矮秆耐密植大豆新品种合农91选育与高产创建
|
摘要
为了选育大豆高产新品种,更新育种与栽培理念和思路及改变品种类型,利用美国矮秆资源育成了矮秆耐密植大豆新品种合农91,并集成了窄行密植栽培技术。2018年在新疆进行高产创建,创造了小面积产量6 356.55 kg·hm~(-2)的全国高产纪录。该品种株高55～65 cm,种植密度45～55万株·hm~(-2),区域试验平均产量3 146.5 kg·hm~(-2),较对照品种合农60增产16.1%。生产试验平均产量3 216.4 kg·hm~(-2),较对照品种合农60增产17.6%。蛋白质含量37.02%,脂肪含量22.42%,中抗灰斑病,抗疫霉病。生育日数120 d左右,需≥10℃活动积温2 450℃左右,在东北春大豆产区为中早熟品种。
In order to breed new soybean varieties with high yield, update the breeding and cultivation concept, train of thought, change variety type, applied new American dwarf soybean variety, Henong 91 of dwarf stalks resistant to dense planting was bred, and integrated with narrow-row close-planting technique. The establishment of high yield in Xinjiang in 2018 had set a national high yield record of 6 356.55 kg·ha~(-1) in small area. The plant height of the variety was about 55-65 cm, the planting density was 450 000-550 000 plants per hectare, and the regional trial average yield was 3 146.5 kg·ha~(-1), which was 16.1% higher than the control variety Henong 60. The production test average yield was 3 216.4 kg·ha~(-1), which was 17.6% higher than the control variety Henong 60.Protein content is 37.02%, fat content was 22.42%, medium resistance to gray spot and resistance to soybean Phytophthora. Growth period is about 120 d, the active accumulated temperature of ≥10℃ is 2 450℃, and it is a mid-early maturing variety in spring soybean producing area of northeast China.
